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.

Great people to deal with. Order rec'd sooner than expected and the Roadmaster equipment was excellent.



by:

The instructions were very good, the video was excellent. If I could make a recommendation, it was a little lacking at the end. Since the Smart car is virtually held together with push pins a little more time spent putting the car back together wourl have been helpful. I'm all done and I have 2 push pins left over and don't know where they go.

I received the base plate for my Miata at 4:30 Monday by 7:00 it was installed and ready to go.A great product fit very nicely.Ordering and follow up went great can’t wait to try it out Just need to decide on the tow bar we will use.The Falcon or Sterling .Thank you for a great product and service.



by:

Installation is a bit involved but worth every second of it for the peace of mind while driving. Had a slight issue with my ordering incorrect parts but these guys went above and beyond to get it resolved in time to not miss my trip. Even rush manufactured them due to not being in stock!! Great company to do business with.



by:

This system worked perfectly from experience. They help from trailers e trailer agents was crucial for guiding me through the process.



by:

Product is great, packaging was rough, the parts were banging into each other inside the box. Box looked like it either had been opened before or had sat in a warehouse for several years.



by:

2007 MX5
The build quality was good....welds
were well done....paint was good
Instructions were pretty thorough.
Lots of trimming away of the splash shield for this install!!
Oh well...no choice I guess.

Purchased the towing adapter for my GMC Terrain a few week ago, received it on time & boxed not damaged. Watched the videos’ about three time on how to do it myself and started one evening and finished it the next morning about three hours with Beer Breaks, LoL. All the parts fix perfectly, had no problems with any of the parts, Product is real sturdy and if you don’t know where to look at the bumper you will not see the hide away receiver brackets. Very nice product, do it yourself and save
Up loading two photos if it will let me one is with hide away brackets installed and the other one you can see is my complete tow bar attached to the hide away brackets



by:

This reasonably priced base plate kit was professionally installed on a coupe that was pulled around the New England states for two months. The kit and the car made it possible to see many sites along the route that would have been bypassed without the toad. The kit is solid and provides secure tow-ability.



by:

Roadmaster base plate for 2010 GMC Terrain. Very detailed instructions, great videos. Product was as described, no holes to drill, just replace factory parts with Roadmaster parts. Everything went together very well. I used the instructions supplied along with the video on my laptop. Hardest part was popping the bumper shroud back on due to colder temperature. I have a fair bit of experience with rebuilding classic cars so have lots tools and reasonable mechanical ability.



by:

Prepared my vehicle for the base plate. The base plate has a manufacturing defect in that the crossbar is approximately.375 inches short. The hole pattern matched on one side but the other side would not line up with the vehicle holes. The mounting plate overlapped the mounting holes by 1/3rd. Clearly, the assembly was short. I find my disassembled vehicle sitting for a week waiting for the replacement to arrive. Hopefully, Roadmaster QC did a better job on the new base plate assembly that I am waiting for.



by:

It is a lot easier to take of the bumper it is all plastic anyway then to take off the air intake



by:

Customer service is very helpful and patient as they walked through everything I needed to set up a car to be towed behind my motorhome.



by:

Installed on 2014 GMC Acadia. Very sturdy and heavy duty base plate. I installed it myself. You will need a little automotive knowledge and more tools then the average do it yourself-er. It took about 6 hours, by myself. It looks more intimidating then it turned out to be. You can't see it when not in use which makes it nice for the wife, since it's her car.
Pictures show the tow bar adapter. Sorry, no pictures of adapter removed.



by:

Parts came very quickly. The base plates are really well make and of heavy material. If you watch the video it is a breeze to install. Make sure you have some new clips for your bumper as the old ones will break, not all but some. I ordered clips from Amazon. I used a vibrating saw with cutting blade and it did nice job cutting plastic bumper cover.



by:

I have bought 3 different ones over the years. They all fit perfectly and the videos are so helpful too.



by:

I was having problems with the bracket that was on the car when I bought it and when it no longer felt safe to me, I looked on your website for a replacement. Lo and behold, this product appeared to be better designed and an easier installation. Putting 8t on today proved that. I am very happy with the product and your service. Thank you very much!



by:

Very heavy duty. Much more than needed for my application but better more than less.
Heavy duty also means heavy in weight. Not easy to lift and move.



by:

my baseplate was delivered on time and in great shape.

  • Recommended Flat Towing Setup For A 2010 Toyota Yaris 5-Door Hatchback
    First thing you'll need to flat tow your 2010 Toyota Yaris 5 door hatch is the correct base plate kit. For that you'd want the part # 521181-5 that you referenced as it is a confirmed fit. 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 All Terain, # RM-522. This has non-binding arms which makes the setup very easy to connect/disconnect....

  • Equipment Necessary to Flat Tow 2008 Toyota Yaris Hatchback 5 Speed
    According to the owner's manual, a manual transmission equipped 2008 Toyota Yaris can indeed be flat towed behind a motorhome. To flat tow the vehicle, you'll need base plates, a tow bar, safety cables, a wiring harness, a supplemental braking system and possibly a high/low hitch adapter. For base plates, I'd recommend the Roadmaster # 521181-1 and # RM-643 for safety cables. For a tow bar, we really like the Roadmaster Falcon All Terrain, part # RM-522. This particular tow bar features...

  • Parts Recommendation for Flat Towing a 2008 Toyota Yaris
    For your 2008 Toyota Yaris Hatchback the correct base plate kit would be the part # 521181-1. The Roadmaster Stowmaster Tow Bar part # RM-501 that you also referenced is compatible with this base plate so these two products would work well for you. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground. For lighting you can use the bulb and socket kit, # RM-155, and not have to worry about cutting and splicing into the vehicle wiring. And...

  • Can the Roadmaster Quick Disconnects be Used with EZ Brackets on a 2009 Toyota Yaris 3 Door Hatcback
    To complete the tow bar setup, you will need a tow bar, base plates and by your reference to part # 201, I take it you are wanting the quick disconnects. You mentioned you have the Roadmaster Tracker Tow Bar, part # RM-020, that is compatible with XL, EZ and Standard style Roadmaster base plate kits. Roadmaster EZ base plate kit, part # 521181-1, will work fine with both your Yaris and your Tracker Tow Bar. With both of these components, you can use the Roadmaster Quick Disconnect kit,...

  • Could Base Plate Kit from Saturn L300 Fit 2007 Toyota Yaris
    Base plate kit fits are very specific for vehicles. In most cases they'll only fit a make and model of a vehicle for a handful of years and there is basically no compatibility between brands of vehicle so you'll need to go with a new base plate kit for your 2007 Toyota Yaris like the # 521181-1 from Roadmaster. This specific base plate kit fits the following Yaris models: 2006 - 2011 Toyota Yaris 3-Door Hatchback 2006 - 2008 Toyota Yaris 5-Door Hatchback

  • Parts Needed to Flat Tow 2008 Toyota Yaris Hatchback
    We have what you need to flat tow your 2008 Toyota Yaris hatchback, but the Curt tow bar # C19745 wouldn't be a great route to go with since we don't have any base plate kits that fit your vehicle that are designed for it. Instead you would want to start with the part # 521181-1 which is a confirmed fit for your vehicle. 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...

  • Parts Needed to Flat Tow a 2007 Toyota Yaris with Roadmaster Base Plate
    Yes, the Roadmaster Base Plate kit part # 521181-1 that you referenced would work well with the Roadmaster Falcon Tow Bar part # RM-520 that you mentioned. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground. For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed...

  • Trimming or Removing Metal Air Deflectors on 2007 Toyota Yaris to Install Roadmaster Base Plate Kit
    Roadmaster is basically giving you a choice with regards to the metal air deflectors on your 2007 Toyota Yaris when installing the EZ Base Plate Kit # 521181-1. If you want to leave the deflectors in place for a cleaner look then you will just need to trim the area outlined in yellow in the instructions so the base plate brackets can be mounted. Otherwise the deflectors on each side can just be completely removed which might be a bit easier but you won't be able to reinstall the plastic...

  • Is Fishwire Required When Installing Roadmaster EZ Base Plate Kit # 521181-1
    When installing the Roadmaster EZ Base Plate Kit # 521181-1 you will indeed need to fishwire the carriage bolts and backing plates during step 17 in order to tighten them to the existing holes in the frame rail. This allows you to feed the bolts and plates through the frame. For the bolts you will want to use a 1/2 inch bolt leader like # 80101-1. I have attached a video demonstration on this process that you can also check out.

  • Will The Roadmaster Base Plate 521181-1 Fit A 2009 Toyota Yaris 2 Door?
    Your 2009 Toyota Yaris will actually be referred to as a 3 door hatchback as they count the rear hatch as the 3rd door. So with that being said, the Roadmaster EZ Base Plate Kit # 521181-1 will indeed fit your vehicle. However, you will need Fish Wire Bolt Leader - 1/2" # C58400 to complete the install. There are only two 1/2" carriage bolts, so you will just need two bolt leaders to get the install done.

  • Recommended Flat Towing Setup For A 2011 Toyota Yaris
    For your 2011 Toyota Yaris, we will start with the baseplates. If you have the sedan or the 5-door hatchback, I recommend the Roadmaster EZ Base Plate Kit - Removable Arms # 521181-5. However, if you have the 3-door hatchback, I recommend the Roadmaster EZ Base Plate Kit - Removable Arms # 521181-1. For these baseplates to be installed, I recommend using the Loctite Threadlocker # LT37420. For your towbar, I recommend the Roadmaster Falcon 2 Tow Bar - Motor Home Mount - 2" Hitch - 6,000...
