I just want to make 2 comments, then sit back and watch:
1. C4 tech, is last century aka 1980's / 90's.
2. as long as the front suspension does what you want it to do, do the parts really matter?
meaning, C3 C4 C5 C6, aftermarket, space alien, cartoon, what ever. As long as what ever parts you are
using, if the car goes around corners, stops, goes straight, does it really matter what parts are used to get
the result? The result being: better than stock, reasonable dollars spent. Keeping up with the Jones-es.
