My new front spring setup... 5k 6" Swift springs (Z60-152-050) with helper springs (H60-060-015)
I'm re-using my Group-N tophats for normal street use because I wasn't happy with the Ground Control camber plates and how rough they were with harsh roads:
I got REALLY lucky (educated guess work mostly) about the ride height. Using the 6" springs with the helpers gets me to EXACTLY where I wanted to be height wise without having to do major adjustment and they have plenty of preload because of the helpers
First driving impression...
MUCH improved! I know most people want solid bearing solid metal camber plates for track events and competitive racing, but IMO so far I have to say they are not right for the street. Too much of a compromise. In order to get the proper use out of camber plates like that, you need significant other suspension modifications, solid metal bearings everywhere and lots of track-worthy upgrades.
I think Subaru had it right with the tS model, and how they use stock mounts with Bilsteins and upgraded springs. Plus the combination of OEM upgraded bushings and you can really have a car that can work extremely well for normal driving but have that extra quality suspension for competition/fun.
I need to do some harder driving (autox) to see how the spring ratios work with the stiffer fronts, and see how much understeer/oversteer the car has. Right now it feels pretty good though so I'm happy for now.
MUCH improved!
