The drawbars, or front arms, on the crossbar-style series base plate kit are supremely easy to mount and remove. Just insert them into the brackets and twist to lock them in place. To remove, simply twist the arms back and pull them out. Once the drawbars have been removed, the remaining brackets are virtually invisible. On most automobiles, the brackets are mounted within the grille - where they remain not only unseen, but protected from scrapes and scuffs as well.

This baseplate worked out fine. While at first glance the installation might look intimidating to some, I found it was not that difficult. I believe a person with average mechanical skills/experience can install this. Since it was a first for me, I took my time and no doubt took more time than a pro, but I know it was "done right". I learned something new, and I saved a bunch of money! The job was made easier by the excellent directions. Probably the most intimidating thing was removing the front bumper cover, but it was actually easy, just follow the step by step directions. This install was on a 2011 Kia Soul. I like the fact that it is nearly hidden, a clean look.

After comparing Demco, RoadMaster, and Blue Ox base plate costs, mounting procedures, etc for my 2012 Fiat Sport, I decided to go with RoadMaster (Kit #522013-1A) for two main reasons: 1) I had the tow bar and mount adapters from another product that were the same specs as the RoadMaster tow bar and adapters to attach to the base plate, and 2) no drilling or other modifications required to mount the base plates. Blue Ox (Kit #BX2800) required I buy their tow bar and other unique configuration adapters PLUS drill two half-inch holes on either side where the base plate mounted AND hammering flat the tips on the corners of the bumper bracket the frame where the base plate mounted. Blue Ox did provide better details on the removal of the facia and bolt removal and torquing actions required for the Fiat. My biggest challenge was the removal of the facia without damaging the clips or other damage to it. Once it was off, the action of removing the bumper core from the end of the frame rails and bolting on the base plate was slick! I took a little over 4 hours to do this, but it was because I wanted to do it right, without damage, and have the confidence I could tow without issues. (Not sure how sequence will show, but labeled the pictures as "Before," "Removal," "Installation," "Finished," and "Ready to Tow.")

This was the second base plate kit from etrailer that I have installed, the first being on our ‘03 Outback and this one on our new to us 2015 Subaru CrossTrek. As usual the response, shipping and delivery from etrailer was prompt and curious. They are my go to place for anything towing related.
Installation of this kit went well with only a few issues, most of which were related to our vehicle not the kit. I knew the car had been hit lightly on the LF corner, but could find nothing of concern body or frame wise when I looked the car over before buying it. Turns out the front bumper reinforcement had been tweaked a tad which made lining the bolt holes up with the holes in the base plates a tad challenging. This made the small angle brackets that go inside the frame heads tough to line up, but in the end it all fit. I did find that it was unnecessary to pull the washer reservoir or the left headlight to access the nut and washer for the long 1/2” bolt. You can easily reach and see the place from underneath after pulling the plastic encapsulation panel. When drilling that 1/2” hole be sure to angle the drill bit UP a tad otherwise you may end up having to grind a flat on the side of the large, thick washer as you can see in my picture from underneath. I used shrink wrap over the nut and bolt since there’s a wiring harness right against it. The picture of the baseplate differs a bit from the pictures so I guess they made some changes. All in all a great kit!

2018 Fiat Abarth install - Videos of install from etrailer helped a bunch. My 2018 fog lights on the Abarth required some trimming on the inside of the bumper cover. Photos in the instructions did not accurately depict my 2018 Abarth, but taking the grill and fog light assemblies off of the bumper cover allowed me to see what needed trimming. Basically a 1 inch notch with the dremel did the trick. I also got the rock guardian and falcon all terrain tow bar. super quick to assemble and disconnect. CLEAN LOOKING INSTALL WHEN EVERYTHING IS REMOVED.



by:

Received the base plate within 3 days of ordering. Very fast and efficient service! Within 15 minutes of receiving the base plate and wiring kit I received an email from Carol at etrailer saying she got notification that it was received and to make sure everything was O.K. Excellent customer service!! The installation was pretty straight forward. The installation tutorial video posted by etrailer was very good and helpful. Will order from etrailer again when the need arises. Highly recommend them.

The Ez4 was went on while watching Video during each step. Used the 2012 Sonic Video. We were able to trim just enough without having to remove the ambient temp sensor. We are happy with the way it looks on the Sonic.

Super fast shipping, nice product and complete installation instructions.

Thousands of miles towed, no issues.

Just what I needed for my toad.



by:

Everything we have purchased from etrailer has been excellent. We have this installed on our 2014 Fiat for towing, and it's worked out great. We've gone a few thousand miles with it, no problem. Love etrailers service, website, videos etc.

Installed on a 2011 Mini Cooper S hatchback turbo. Previous reviews were pretty spot on. Lots of plastic goes into these cars! My install (including brake light wiring), was 7 hours start to finish. Hardest part was removing the bumper facia to get at the metal bumper underneath. Be patient, take your time so you dont break any plastic clips!
The base plate itself is VERY robust compared to the oem bumper! Adds about 20#. I did have to trim away some plastic flashing behind the facia where the air scoops go. Easy to do with a Dremel tool.
When done, it is an extremely clean look!
Very impressed with the fit and finish. Very easy to hook up. Went with Falcon 2 bar. Tows very well!
Thanks etrailer!!



by:

Fairly easy to install however it requires removing the front (nose) of the car. I was amazed at how much plastic goes into making these cars. It took about 3-4 hours to take off the front remove the factory 'bumper' that the RoadMaster Base Plate replaces and reinstall everything. I had problems because someone had removed the front of the car previously and had not put it back together properly. It all worked out and I'm loving how easy it is to hookup and unhook. I had a dolly previously and this is so much better. When I sell the Mini I'll restore the front end (replacing the grille) unless the new buyer wants to tow it. The etrailer and Roadmaster teams are great to work with.

First of all, thank you etrailer for getting the Baseplate Kit for my Chevy Spark to me in time for my trip. Everything I needed was in the box. The step by step instructions were very easy to follow. I would definitely take their suggestion to read and understand the instructions before beginning the job. That step allowed me to always know what was coming next. Several holes need to be drilled, no problem with location, it is all in the instructions. Be sure to have good sharp bits. The whole process is an easy bolt on. I work slowly and got it done in one afternoon. At the end, after installing the baseplate, when you put the front facia back on the car, they suggest leaving off the Styrofoam inner bumper but I found no need to do that as it still fit right back on no problem. It would be up to you to leave it off or not. I thought it would be safer with it on there as was the original. In the end I added a light kit with a 4 round plug on the front. Very well thought out for Roadmaster to supply a place to mount the receptacle. Thanks again, I can now leave on time and take my car with me.

I bought and installed base plate and wiring on a 2018 Ford C-Max hybrid car. The wiring was a little complicated due to the hybrid setup on the car, however, everything worked out well. I have done this on several other cars I have towed behind my motorhomes. All products and help from etrailer.com was excellent. The video presentation was very helpful.



by:

I installed it on a 2012 mini Cooper S. The video was of a slightly different model than mine, but was very helpful. One thing to note is that the model S has a turbo charger so it has two plastic air intakes in the lower bumper area. That was not mentioned in the instructions or the video. The fit of the towbar bracket was perfect! Very little of it shows from the outside.



by:

installation instructions were clear and very helpful, took me about 4 hours to install, would have been faster if i had attempted anything like this before.. removing front fascia and trimming the openings. Easy to use.



by:

Very well made. Other than a couple of holes not lining up very well, which I have never seen anything line up perfectly, it was fairly simple to install. With the instructions that came with the base plate, that were very easy to follow, we were able to install with very little problems, and we are not all that mechanically incline. Lol



by:

Great product and installation went very smoothly. Installed myself in about 2 hours. Fit perfectly and mounted easily to the car. My Stowmaster tow bar mounted right up to it. I deliver motor homes for a living and can already see how this setup is going to save me lots of time and aggravation over old fixed tow bar set-up I had previously.



by:

The package was shipped from your warehouse 1/4/2012 at 2:09 PM and arrived at my house in Colorado Springs 1/6/2012 at 1:08 PM, that was great service and a great product.

I finished the installation of the kit on my new 2012 Ford Fiesta at about 8:00 PM on the same day I received the kit (1/6/2012.)

Thanks for the GREAT service



by:

the install directions were on the spot. install was time consuming but, relatively easy with the car on a set of ramps. one year and 9000 miles later. everything is still solid and tight



by:

Ordered the Roadmaster Cross-Style Base Plate with Removable Arms Kit after reviewing the information on the etrailer web site. Nice video showing the product installed on our model of vehicle (Fiat 500). Ordering online was easy and shipping was fast with excellent communication through email and tracking.

After receiving my order, I then discovered the Quick Disconnect Tow Bar Assembly is not included in this model of base plate kit and has to be ordered in addition. I was able to determine after a phone call and email exchange with customer service. Interesting it is listed in the online catalogue as a replacement item.

  • Parts Needed to Flat Tow a 2014 Hyundai Accent
    I did some checking and it looks like the 2014 Hyundai Accent is only flat towable if it is the manual transmission model. The 2014 Honda Fit can be flat towed with either transmission style but it is not recommended to exceed 65 miles per hour. I would recommend consulting the owners manual of either vehicle or contacting a dealership to be sure. We only carry base plate kits for the Hyundai Accent though. So that might be the deciding factor. If you were to get a manual transmission...

  • How to Tow 2013 Kia Rio behind Motorhome
    I did some checking and all models of your 2013 Kia Rio can only be towed with a tow dolly like the Roadmaster # RM-2050-1 behind an RV. You would most certainly damage the transmission of your vehicle if you towed it with all four wheels on the ground.

  • Base Plate and Flat Tow Parts for 2014 Hyundai Accent with Manual Transmission
    I checked with Roadmaster and the correct fit for base plates on your 2014 Hyundai Accent with a manual transmission is the Roadmaster Crossbar-Style Base Plate Kit # 521634-1. The base plate kit you referenced only fits later model year Accents. In addition to base plates there are a number of other parts you will need to safely flat tow your '14 Accent, which I'll list for you. - Tow Bar: Roadmaster Falcon All Terrain, Non-Binding Tow Bar # RM-522 - Safety Chains: RoadMaster 68" Single...

  • Parts Needed to Flat Tow 2014 Kia Rio LX Manual Transmission
    I did some checking and it looks like the manual transmission versions of the 2014 Kia Rio like yours can be flat towed behind a motorhome as-is without issue. So for a base plate kit you'd want the part # 521634-1 which is a confirmed fit for manual transmission sedans like yours. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon 2, # RM-520....

  • Blue Ox Base Plate Compatibility With A 2014 Kia Rio LX Sedan
    The Blue Ox Base Plate Kit # BX2724 you referenced is designed for use on 2014 Kia Rio Hatchbacks so you would need the Roadmaster Crossbar-Style Base Plate Kit # 521634-1 instead for your 2014 Kia Rio LX Sedan. The # 521634-1 is designed for manual transmission models only and does not fit models with foglights.

    The Demco base plate kit part number # DM9518306 does not fit your 2016 Hyundai Accent but I do have a great solution with the Roadmaster base plate kit part # 521634-1 but you would also need the adapter part # BX88178 to connect to your Blue Ox tow bar.

  • Parts Needed to Flat Tow 2013 Hyundai Ascent with Manual Transmission Using Blue Ox Rangefinder II

There is not a Blue Ox base plate kit for your Ascent that is compatible with a Rangefinder II towbar.
