SoCal NA/NB Koni Yellow coilover setup: GC's+Swift+extended top hats
Available on
Camarillo, CA

Up for sale is a well dialed in Koni yellow + ground control coilover setup. Its an excellent multi-purpose (street/Auto-X/track) suspension that will last the lifetime of your car. Was running a 1:32.X (Streets of Willow CW&CCW) on a mostly stock NA with RSR-RRs, a street alignment, and a mediocre driver thats only run the track a handful times. Pairs best with tires in the 200-300 treadwear range. Has roughly the same suspension travel as Xidas due to the extended top hats. Setup is also extremely drivable on the streets as its very compliant and has lots of travel. Damping, ride height, and rake angle were dialed in pretty well over the past few years and I can supply the dual-purpose alignment I was running so you can pretty much just bolt everything together and be 90% of the way there. Its the best dual purpose setup Ive driven on but Im transitioning to 100% track car and got a new setup with spring rates that are beyond what these can reliably damp. Picture shows current ride height that these are set at. You may adjust if you want, but any lower and you will touch the top of your fender well at full compression.
Koni Yellow/sport dampers w/ only ~10k miles on them: mostly street miles and ~7 track days
Swift springs: 9kg (500lb) front, 6kg (350lb) rear
Ground control sleeves
Dust boots that actually fit inside the spring
Foam bumpstops, trimmed to engage at the last ~10-20% of travel
DIY extended NB style top hats
Trimmed off ABS nut, still have them for what its worth
Also comes with 3 adjusters, some extra hardware, spanner wrench, factory spring perches, replacement set of perch circlips, replacement top hat bushings, and KYB sleeve adapter rings.
Asking price: $800. Can ship at buyers expense neatly packed in the packaging that I got my Xidas in.
