Show me what 17's your running on frst's
May need to go to some because my brake upgrade is larger than I thought, I'm going to try with 16 but I'm not feeling very lucky tbh

 

Unless just driving in straight lines fiesta turbos drive very bad on 17s, suggest you rethink your brakes as you cocked up

 

You tried spacers or different et rims? Mines on cosworth brakes and the comp mos fit great.

 

Exactly my thinking

 

It's because thy are frs brakes, 325 mm, so rather large

 

Jesus to large what you running a gtr block?

 

Start with the braking and handling first then full zetec turbo is my plan, was more of the fact they were there as I was looking and though it was a brilliant idea, just a little concerned about needing 17's now, don't like the idea of running on 17's, as above it'll handle like a dog

 

Mine stops great and running a t34 rear disc conversion aswell. Yeah will look to big aswell.

 

id try compomotives in a 16 ,they might fit.. as for 17's i ran them years ago with no major issues but a fair bit of rubbing...look at the new ff mag,rob's fiesta on the cover has 17's as he has massive brakes ..i now run 300mm disc's with AP racing 4 pots under 15 inch comps so you might get away with 16's

mine;

 

16" wheels max 17s are just wrong on FRSTs, sell the brakes on and get some 300mm

 

Get some 16s i cant rember which et either focus off set or saxo off set and thay will fly on.
Oh course use the correct offset on the rear.

 

Yeah the one on the cover, oz superleggas I believe? They don't look too out of place IMO, and yours doesn't look silly frsjon, better than I thought 17's would look anyway,
Here's the brakes

And the comps


I sort of test fitted them and there was one bit of the caliper that was catching, so I've ordered a set of brackets to fit them properly and see what the score is, maybe a bit of caliper filing on the notch at the top might sort it

 

Ideally I don't want rid of the comps but I think I agree with no bigger than 16's
