Snowbear77 Member 102 Member For: 4y 9m 2d Gender: Male Location: Perth Posted 05/12/22 07:00 PM Share Posted 05/12/22 07:00 PM Finally found a set of 19 inch FPV Twists, and now will be finally going the brembo upgrade. I've read in several places that the 6 pot brembo's will fit under these wheels, though the question I have - what is the maximum size rotor I can fit under a set of 19 inch twists?

( if that helps ). I just cant figure out the max size of rotors that can fit under the FPV 19 Twists.....

I can't tell you without knowing how they'll make the bracket or fit the caliper test-fit and measure the gap and go with whatever rotors fit inside that sizing.

Going any bigger is pointless because the pad can only engage as much rotor as designed. Plus, unless you go 2 piece rotors, you're adding unnecessary sprung weight with bigger rotors Link to comment https://www.fordxr6turbo.com/forum/topic/96856-brembo-6-pot-vs-rotor-size/#findComment-1716122 Share on other sites More sharing options...
hjtrbo Bronze Donating Members 328 Member For: 14y 4m 5d Posted 06/12/22 09:53 AM Share Posted 06/12/22 09:53 AM For extra inputs sake, I got a set of 355 rotors and Brembo 4 pots here off a FG-X XR8. The diameter part of the equation fit under the stock FG Mk1 18's but the offset part of the equation is a fail. Calliper hits the rim spokes. As mentioned by the brains trust, it all comes down to how the bracket and rotor hat are sized. For what it's worth I've got a set of big pad area AP 6 piston and a 355mm rotor hidden in behind a set of 17's on my HJ ute. What I'm trying to say if you ignoring the blowing my trumpet part, is it all comes down to measurement and employing someone that knows what they are doing. And I'll add another curve ball, for some reason in Australia you will pay mega bucks for a custom brake bracket and rotor hat. From my experience, they can be had significantly cheaper going overseas if you are able to cad the designs up yourself and specify material / tolerances etc. Link to comment https://www.fordxr6turbo.com/forum/topic/96856-brembo-6-pot-vs-rotor-size/#findComment-1716123 Share on other sites More sharing options...
