Aftermarket Suspension Question
Don't get a 4 link set up, the 4 link is complete **** because the 2 upper control arms will create bind which really hurts cornering. You want to go to a 3 link set up. I personally use Maximum Motorsports for my suspension and love them, and I've autocrossed my car plenty.
It looks like this is for a classic? In that case go with a pushrod rear suspension set up.
Bullitts are better than Bullets
