Anyone know of 1/4" to 1/2" rear Coil Spacers for the 350Z and/or G35? I'm installing 350Z H-Techs on my G35 Sedan and want to keep the rear drop a bit higher than the front. (It's hard to get a nice looking drop on the Sedans because the front fender gap is about 3/4" higher than the rear. You really need to drop the front a bit more than the back to look right.)

Anyway, I've heard of people using rear Coil Spacers to help this, but the only ones I can find are big ones for Trucks/SUV's. Any ideas?
