IMO coilovers are great provided they are corner weighted and not to low otherwise you may as well go with a sports spring and shock.
My best mod so far is my eibach ARBs. they have made the car really neutral and controled in the bends at all speeds. My WALK is actually booked in to get fitted tomorrow. had it for ages but jst not fitted it.Im expecting alot from the WALK, and i should find out on saturday how good it is as im off back to the nurburgring for the day, i was down there earlier this week so will have a good comparison provided the heavens dont open up.
My issue at the moment iwould say is my brakes. they are fine for one lap of the ring but do not cool quick enough and then need ages to cool. they were adequate for a few laps of uk track days though
thinking of going S3/R32 setup but wth tarox g88 discs and DS2500 pads, and braided hoses with some race spec fluid and tyrol caliper bushings
