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

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.

  • Needed Items to Flat Tow 2007 Mini Cooper S hardtop with Sport Suspension
    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. For a tow bar, I suggest the Roadmaster Falcon 2 Tow Bar, # RM-520. This hitch-mounted tow bar has stainless steel, telescoping arms that automatically lock into place. Its large hookup radius allows you to connect without perfectly lining up your vehicle. Easily folds up to store on your RV. You will need safety cables,...

  • Parts Needed to Flat Tow 2008 Mini Cooper Hardtop S
    For a Roadmaster base plate kit that is compatible with your 2008 Mini Cooper Hardtop S and your Nighthawk tow bar part # RM-676 you'd want the Roadmaster EZ part # 521877-1. For lighting you can use the diode kit, # RM-152, 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 that you will install on the front...

  • Flat Towing Base Plates for a 2010 Mini Cooper S Hartop

I recommend the Roadmaster EZ Base Plate Kit - Removable Arms # 521877-1 which is confirmed to fit your Model S Hardtop. Then I recommend the Roadmaster Falcon 2 # RM-520 for your tow bar and # RM-643 for your safety cables. You can use the plugs # RM-210 when not in use if desired. For your wiring, I recommend the Roadmaster LED Bulb and Socket Kit # RM-152-LED....

  • Tow Bar for Flat Tow Mini Cooper 2600 Pounds
    To flat tow your 2010 Mini Cooper Convertible S model you will first need Roadmaster # 521877-1 base plates which are hidden well and have easy to use twist-lock mechanisms. Next you will need a compatible tow bar. I strongly recommend a non-binding tow bar because with it you will not need to have the vehicle and motorhome perfectly straight and level to hook up or disconnect. If you ever had to fight with a tow bar because it bound up then you know how much of a pain, literally and figuratively,...

  • Recommended Baseplate For A 2008 Mini 2-Door Hardtop
    Hey John, If you have a 2008 Mini Cooper hardtop S-model or 2008 Mini Clubman hardtop then you'll need the Roadmaster # 521877-1. This will work with Aerodynamic Package, but not with Sport suspension. If you have a 2008 Mini Cooper hardtop base model then you'll need the Roadmaster # 521878-1. This does not fit models with Aerodynamic Package or Sport suspension. If you haven't picked out the rest of your flat towing setup then I have the following recommendations for you: Tow Bar:...

  • 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...

    The Roadmaster EZ Base Plate Kit, # 521877-1, is specifically designed to be used with the removable arms that come with it in order to flat tow the vehicle behind a motor home so a bike rack will not fit. For your 2009 Mini Cooper S, I recommend the rear mounted Curt Trailer hitch, # 11130. This is a class I trailer hitch with a 1-1/4 inch square receiver. You will need to make sure that the bike rack you plan to use is compatible with a class I trailer hitch and, on class I trailer hitches,...
