So I was reading in the general section and nobody seems to know anything about the sport suspension. Is it stiffer springs and thicker swaybars or just thicker swaybars? I hope the SCCA crowd knows the difference. Basically if you just get the base suspension and throw on a set of Konis will the car still be competitive with the sport suspension cars with all else equal?

Are there any G-stockers without sport suspension doing well out there on a regional/national level?

 

Are you talking R53 2002-2006 or R56 2007+

 

Here are the 2002-2006 specs.

Front Bar:
One 16mm
One or Cooper with SS 22.5mm
Cooper or MCS with SS+ 24mm

Rear Bar:
Standard bar unknown
Cooper or MCS with SS+ 17mm

2007+ I don't have any data

 

R56, 09 specifically
