I've been trying to get a handle on the different options (types and front/rear thickness ratios) but have to admit to being slightly confused by how they are packaged up and sold (as a set) by various suppliers. The H&R ARB set go thicker at the back (26mm) versus front (24mm) KW set go thicker at the front (26mm) versus back (23mm) Whiteline set up seem to go thicker at the front (24mm) versus back (22mm) Eibach set again go thicker at the front (26mm) and only (22mm) at the back Regardless of which option I go for, i'll be fitting adjustable drop-links to remove any pre-load. There seems to be a lot of chat on ARB ratios for the 8L model but I cant get much in the way findings on what works best for 8P (understeer is obviously not good but neither is the back end going light... and i'm not that good on the throttle control...oops). H&R set up would point to a more entertaining ride, but why are they the only ones out there with that approach (the S3 has been out for a very long time now. I'm drawn towards H&R approach but has everyone else got it wrong ? or are they catering for a different type of customer requirement...or is it just the way that the various tuners/parts suppliers are packaging them up as sets for sale ? The car is going in next week for full Powerflex polybush (front and rear suspension - 9 different sets!), THS engine/transmission mounts, Vibratechnics dogbone insert, Whiteline - steering rack mount, anti-lift kit, bump steer correction & Superpro adjustable ball joints (along with replacing a few oem suspension bits & pieces). I'll be fitting B16s, Quaife ATB Dif and uprated Haldex controller in the next phase of suspension developments (will be keeping it at the maximum height the B16s will allow when it's on the road - prefer the very stock look). Thanks for any help/insight.
