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

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.

The instructions were excellent as is the product quality. With very little effort I was able to install these on my Mini Cooper in less than 1 hour. With only my garage area (no lift) and minimal hand tools the installation was very easy and the end result looks and performs great. 636712

Great product, price and service. Not the easiest to install. Only Roadmaster base plate that required that the bumper be trimmed but Minnie is very low to the ground. 315099

2007 Mini Cooper S

Very well constructed. Fitting right side took some adjustment, I had to clearance the lower member hole in order to fit the bolt. I installed the base plates myself, after the prospective mechanic claimed this was the incorrect fitment. Subsequent calls to Roadmaster produced a "No Fit" pronouncement, in spite of the lookup and even the printed instructions. Undaunted, I proceeded, and the fit was successful. YES, this DOES fit a 2007 Mini Cooper S Convertible. 214849

2005 Mini Cooper

Installed on 2005 mini cooper convertible. Choose this base plate for our mini since it provided highest attachment height for tow bar (12 inches off ground, only requires 3 inch drop from back of RV), and attaches to mini frame more substantially that blue ox. Installation directions are nearly perfect, we had to widen holes on passenger side to line up with frame. Modification was approved by Roadmaster. 195240

I absolutely love my eTrailer purchase. Much better price than through any dealer. Directions were clear and easy to follow. And I did the installation all by myself. Thanks eTrailer. 24899

Review from a similar EZ in Base Plates


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. 775432

Review from a similar EZ in Base Plates


Very happy with this product. Installation was pretty easy. I see no reason to pay someone to install this. True you have to take the bumper off and a large metal support beam but it was pretty easy. You just have to take it slow and not get frustrated. The bumper on the Honda Fit is held on with a gazillion little plastic clips and snap joints. Everything fits tight on a Honda so you have to be patient. My only complaint is they don't give you the exact torque settings. I had to consult a shop manual to get the correct torque values. They give a table at the end of the instructions that gives common torque values for various bolt sizes. I thought that was lame they could have given the correct value from the shop manual. Certainly not enough to lower my rating. This bar is awesome and when the drawbars are removed the base plate is almost completely hidden. My wife wanted nothing to show on the front of the car. She was very pleased with it. In the picture attached the bar is almost completely hidden. All you see are two small black circles. It takes about 2 seconds to mount the drawbars, just twist and go. VERY sturdy. I tow my Honda behind the motorhome with confidence. 80709

Review from a similar EZ in Base Plates


After checking and verifying with Kelsey what my 2006 Mazda Miata needed for tow plates, I ordered and in a very few days, it arrived at my doorstep. They also did a great job for my 2018 Jeep Cherokee, which I am towing behind my RV now. They have the most knowledgeable folks to help to get the correct parts and if you find a price lower, they will refund the difference. I can't think of any other Company that does that. This Company is my only go-to place for anything towing related. Here is a picture of my installed BlueOx base plates on my Jeep and will update as soon as I get the Miata installed, and get a picture of that also. 527318

Roadmaster base plate and tow bar is just a perfect combo to tow my car behind my class C mercedes RV. A little over five thousand miles already with no issues at all,with the included instructions it was easy to install with basic tools and with the removable bars i take them off when i get back home and I can just drive my car without them and no one can't tell it is a tow car.. 728507

Review from a similar EZ in Base Plates


I like the Roadmaster tow bars but I am 2 for 2 with fitment issues. The one bolt hole did not line up with the frame, after trying to adjust and take measurements for an hour, I had to grind about an eighth of an inch on the frame hole. This issue doubled the installation time. Had a similar issue with my Miata tow bar 7 years ago, but had to enlarge hole on tow bar. The etrailer video was excellent and this would have been a simple install if the tow bar fit. 571342

I don't remember if these were for installing on the Buick or the MG. If they were for the MG, I have used them a good many times and they are fine. If they are or the Buick, I have not used them yet. I just need to finish up the wiring and the aux brakes for it. 415358


Comments
Thanks for asking. I installed them without a problem with the intention of pulling the Buick behind the motor home till I realized the Buick was 1000 over the tow limit of the hitch on the motor home so wound up never using them. If I ever need to tow it, they are there.

Review from a similar EZ in Base Plates


I ordered the base plate for my 2010 Ram. It was shipped right away and it arrived on the fourth day. I have no complaints about ordering this product it was quick and efficient to deal with etrailer. The base plate arrived and was as advertised except for the bolts with the fish wire to do the one side of the bracket. It said in the instructions to use them. It was not a big deal. I had to do a little grinding on the inner bumper to get it to fit which was a bit of a pain but that is not the fault of the product. This is the second Roadmaster base plate I have installed and would order another if I need one! 671692

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. 183405

Review from a similar EZ in Base Plates


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 200736

Larry, Im assuming that youve towed your vehicle by now. Are you still happy with your choice and did you purchase any additional components like the electrical kit, fuse switch..etc Dave R

Have been using this tow adapter now for a while and everything works out fine, Easy to connect. I did purchase the Wiring harness from the tail lights to the front of the car instead of making it as I usually do and the connection to the RV from that connection and glad I did, the wiring harness also went easy and very fast.

You have most of the parts correct, but there are some specific items you will need for your Mini.

  • Recommendation For Tow Bar Base Plates For 2003 Mini Cooper - Manual Transmission
    Regrettably, The Roadmaster EZ Base Plate Kit, Item # 521876-1, does not fit your 2003 Mini Cooper. The right base plates for your Mini are in the Blue Ox Base Plate Kit, Item # BX1303. Unfortunately, they will not work with your Roadmaster Stowmaster 5000 tow bar. If you are interested in changing to a tow bar that fits the Blue Ox base plates then I recommend the Blue Ox Acclaim Tow Bar, Item # BX4330. I am attaching some articles and a video to assist you.

It will also fit your Falcon Tow Bar part # RM-520 without the use of an additional adapter. The Optronics Magnetic Tow Lights # TL21RK would be a great option.

For an adapter to allow a Blue Ox Alpha # BX7380 tow bar to attach you need the part # RM-032. 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 vehicle. This comes with a round 6-way connector...
