yep. been there, done that....got the t-shirt.
1....I have the chicane kit on my car with the tru-turn kit, ridetech tripple adjustable shocks and spindles, and spc upper and lower arms. with the chicane top mount and the chicane lower mounts bolted AND welded to the bottom of my spc arms, my lowers are parallel to the road using a 5" stroke shock with a 12" spring.
with this set-up, my sub rides 3.25" off of the road. my front wheels are 18x9.5's with 275/30 tires. the fender comes within .5" of the top of the wheel. the speedtech tq arm is set up with the same 5" stroke shock and comes within the same .5" of the top of the rear 18x11's with 335/30's.
this set-up took some time and fab to make work with the coilovers at the reccomended spot in their stroke. but it was worth it to me.
2....any brake kit that will work with stock 1st gen spindles will work with the ridetech spindles. the guy that had the trouble on the other site was trying to bolt on a kit designed for the afx spindles which use the c5 brakes directly with no adapter brackets. all he needed was the appropriate brackets from kore3 and they would have bolted to the ridetech spindles.
also, be aware that the c6z calipers are very thick and require nearly 2" of wheel pad. most shelf wheels will not clear them without spacers.
