This question has probably already been asked but I have 2012 Mini R58 JCW. I have the upgraded JCW suspension but I was wondering if it would be worth upgrading both the front and rear sway bars as well as maybe a M7 Under Strut System?

Also does anybody know what the mm size is on the upgraded JCW factory sway bars?

Thanks so much, Alex

 

I have the same car as you and a couple of years ago I put on a 25.5 mm Hotchkis
rear bar (hollow). Big difference.

 

Like he said the Hsport comp bar set on the middle setting will be ideal for your MINI.

+1 with Way and minirab
A pretty good explanation of the virtues, or lack thereof, concerning the front sway bar can be found on post #2 on the following thread.

Thank you everyone... Just ordered the 25.5 mm Hotchkis rear bar... you guys rock.

 

Is this an easy install? I have the same model car.

 

How to instructions part 1 & 2.

 

Thanks for the link, too complicated for me. But Madness is actually close to where I live. Are their 22 mm swaybars as good as the 25.5 Hotchkis?

 

If you compare the two, the numbers are nearly identical....except.
Madness: +228% +297% +384% $225
Hotchkis: +226% +294% +383% $277

 

Got it installed today, what a difference it makes! Should have done this 4 years ago when I got my car!

 

Hmm, I also have the factory Sport Suspension. I think it's an 18mm rear bar. I may go for the 25.5mm Hotchkiss deal. Any idea who does it in Phoenix? Maybe they do it at Mini North Scottsdale where I bought the car. I had Way put one in my 2007 MCS, a 19mm solid one, Alta I think, at a Las Vegas Mini gathering in 2008.

 

I'd venture that any good auto mechanic could do the job, it's just nuts and bolts. A dealer's shop charge would be excessive no doubt.

 

The rate for labor in the shop that installed was $100/hr and it was 1 1/2 of time.
