Features:

  • Hidden bracket design provides improved aesthetics compared with standard brackets
  • Drawbars are easily removable - just twist and pull
    • No pins or clips required
  • Computer-cut, all-steel construction provides exceptional strength
  • Black powder coat finish is durable and corrosion resistant
  • Simple installation - no welding required
    • Custom base plates ensure a perfect fit for your vehicle
  • Compatible with Quick Disconnects and all Roadmaster tow bars

The drawbars, or front arms, on the EZ 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.

Great installation instructions and video. Was an interesting and fun project installing in our Mini-Cooper



by:

Was pretty easy to install once you deal with the Plastic Rivet Retaining Clips. It's probably a good idea to have some spare clips available as they are pretty easy to break while removing.

eTrailer offered the best price and shipping was free and fast.

Put this base plate on my 2008 Mini Cooper S over the weekend. Took about 5 hours including adding the Roadmaster tail light kit. Instructions were great and also the videos on the site helped as well. This can easliy be done by one person with the right tools!!
Great Products! Thanks

Installation instructions were very good

Fit perfectly and the directions were spot on. Took me about 3 hours not including the wiring of my Mini Cooper. That took me an hour and a half.

Great product went in easy. The pictures on the directions need to be clearer, but all in all great product

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.



by:

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:

After 1 year of full-time use I am very happy with the base kit. It was relatively easy to install with the aid of a car lift. I would imagine that it would be a little harder without.



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:

Great product.
Excellent fit.
Everything
has performed wonderfully.



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:

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



by:

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:

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.

    At present there is only one option available for the 2007 Mini Cooper Hardtop S Model, the Roadmaster EZ Base Plate Kit, # 521877-1; this is confirmed to fit your vehicle.

  • Recommended Tow Bar for 2010 Mini Cooper
    The best tow bar is going to depend partially on the base plates you have for your 2010 Mini Cooper hardtop S model. The only confirmed fit we have is the Roadmaster EZ # 521877-1, and if you have the same base plate kit the tow bar I recommend is the Roadmaster Falcon 2 # RM-520. This is a high quality bar that is very popular due to how easy it makes the connection between the tow car and dinghy. A look at the customer reviews of this tow bar is also telling and speaks to the Falcon 2's...
