Kic's. ive been using them for 5-6yrs now on my various cars, never had an issue.

the Eibach's ive used on my Z's fronts are 20mm (built-in stud type) and no issue so far. i agree with ChrisSlicks that it probably has to do with the thickness and reinforcement (or lack of) on the 15mm.

Interesting, for the Project Kic ones, the hubcentric ring is optional (sold seperately), and removable. Well, if these don't work out, I'll give those a try.

yah, most people run lug-centric wheels so you dont necessarily need the rings. but for our hub-centric wheels the ring is required.

ichiba's are the same way and their rings are actually the same dimension as the Kics. but the biggest difference between ichiba's and kics was that ichiba's overall craftsmanship is low and there's too much play in the ring making them near useless for hubcentric wheels... that's probably why a lot of folks were getting vibrations using ichiba v2 type on the fronts. their tolerance is too wide making it a hit or miss.

im currently using (i should say testing) 20mm ichiba's on the rear of my G35C running lug-centric aftermarket wheels with no issue for the last 2k miles. i would not use them for the Z's front using stock wheels.
