Ok I am lowering my car soon. I have already H&R Sport springs which rate a 1.75 F/ 1.5 R which is a pretty decent drop on some 17's. Now I want to get Koni yellows since they are the best of he best for 5th gen accords. Now what I dont understand is this.The NEUSPEED/Koni shocks also feature an adjustable spring perch to level the car (5 machined grooves on the shock body for 5 positions of adjustment). What does that do for me, get my car to go a little lower or something or vis versa.
