Sorry for shaky video!!
This is my R56 2009 Mini Cooper S JCW stage 1 kit with Group4 Autosport rear diffuser and splitter it was installed at Minis in the mountains 2010 and Minis take the states 2010... by my husband and the guys from group4!

 

Would you recommend this as a good mod?

 

Not that one. For 1/2 or in my case, for a 1/3 of the price, you could get an OEM GP2 diffuser that'll connect perfect to the OEM existing underbody panels and have the downforce you're looking for.

 

I was hoping to avoid the costs of the jcw bumper and paint....

 

Ah that's right I didn't consider that was an additional expense. Sorry. Not many options out there for the stock bumper. So I suppose this would be your best bet. If you do get it though I hope you are utilizing it for its downforce capabilities and not just for show because I would hate for you to chop up some plastic bits or drill any holes and you regretting the choice.

 

I'll admit that there is a little bit of "it looks pretty sweet", but it is mostly for the downforce. My rear tires have been wearing a little choppy, and I am thinking that if the rear end was pushed down some more, that would cure it. I'm thinking the diffuser and the GP style spoiler should about do it

 

If you are talking about a cupping that is occurring on the outside edges of the tire, I typically associate that with poor shocks.

 

No. Chopping in the center
