Jellybean Posted May 24, 2014 Share Posted May 24, 2014 Hey I Have an 93 car, she had the 12 bolt 220mm Diff from Factory (AKA UK Spec) , she has UK Brakes all round How do I know if she has UK rear brake rotors? They are different sizes to Jspec, does anybody know the diameter of UK and Jspec Rotors? On a side note , does anybody make a rear Brake rotor where the bellhousing doenst rust over time? Can you use any 2 piece rear rotor with OEM UK 2 pots, brembo, AP racing etc? Only rear brake Rotors I can see are OEM Rotora Stoptech Blueprint Black Diamond Does anybody have any experience of the Stoptech, cross drilled rotors look like a nice piece of kit http://www.mvpmotorsports.com/Merchant/catalog/jdm/t/supramkiv/p/stop/OED.jpg Quote Link to comment Share on other sites More sharing options...
