c4 brake upgrades in second gen Fcar

[WSSix]

What year C4 and is your C4 donor car a J55 car? C4s could come with 13" front brakes. That is the J55 option. The 13" C4 front brakes are good brakes but the C5 13" front brakes use a larger pad and wider surface area on the rotor. You get more clamping force with C5 brakes. This is not to say the the C4 brakes are inadequit though. You could stay with them and be happy I bet. If you want larger than 13", there are plenty of kits out there that adapt C6 front brakes to C4s. Check with Tobin at Kore3 and see if he has anything for the vettes.
