But then again there is also Tein and HKS Hyper available. As far as brakes don't get Skylines. I am having some work on making a 13.5 AP racing caliper setup for our 300ZX. Or you can dilwoods.. So in others spend the 1.5k-2K and get something quality..
If you have any other questions just ask them..
If you want the cheap solution on suspension go with Eibach's and KYB AGXs..
