i suppose i want my car to drive as a standard s1 does but with a stronger roll bar system.
I haven't really driven a rs1600i so don't know how diferent it drives to the s1. But i do know the s1 anti roll bar seems to be ok but never looked a heavy duty unit.
Want my car to be able to handle in terms of street driving and be good enough to share a track day and everyday use aswell.
