Planning to upgrade front SB, install rear SB hopefully before summers is out. Also KYB's , shocks in the car now plain suck.
Anyone recommend PST polygraphite front end rebuild kit, or stay with the OEM rubber bushings?
KYBs are a great shock! We offer both Polygraphite and OEM-type rubber bushings. Rubber replacement bushings will just bring your car back to factory handling levels. Polygraphite bushings are near-zero deflection and are a great upgrade from rubber - plus, they will never dry rot so they will last practically forever.
If you grease Polygraphite liberally before installation, it shouldn't squeak. That being said, from time to time (quite rare) we do hear about people who install their bushings properly but still hear some squeaks.
