Which brake upgrade will fit my current wheels ( 17 inch oz Polaris ).Not sure which to go for between AP,BREMBO or ALCON/PRODRIVE ,Thanks in advance....Gary

 

All should fit, OZs are usually ok for clearance.

Recommend you go for AP, 330mm, 4 or 6 pot assuming you dont want to ever run a smaller wheel than 17" - if so AP do a 16" kit (Prodrive/Alcon also requires 330mm - 17"rim)
Brembo can fit under 16s
