Rears first? With big front brakes you don't even need to change the rears. 13 inch front rotors work just fine with factory 10 inch drums in the rear. I have several road race customers who run that setup. My 13 inch Viper kit up front is all the brake an A body will need up to about 150 mph.
Yep, that is Tim's car. He runs one of my 13 inch front rotor kits with late model Viper calipers. The Mustang rims bolt right on without a spacer.
At the moment he is running 17x9 rims but he has also run 17x8 rims in the past. That car ran 10 inch rear drums for several years. He recently converted over to rear disc brakes using a bracket system that I designed which retains the tapered roller bearings. The rear discs are slightly lighter than drums and they have a linear response which is better for high speed racing.
AndyF-
any car guy who uses terms like "linear response" definitely has my respect. you rock man!
thanks for sharing your knowledge and for your contributions to our hobby.
More specific about what? If you already have 17x9 wheels then you'll need different wheels with the 13 inch kit since the hub surface is moved out about 0.750 inches. The 13 inch kit is designed to work with Mustang rims that have the 5.72 backspacing. On some cars you need to go with even more backspacing than that. It takes some real effort to cram big brakes and big tires into the small space that the factory engineers left us to work with.
that is what i pretty much needed the specifics on. and i am running mustang 17x9 bullitt wheels! i cnc'd some spacers at work (10mm thick) and i am still hitting the outer tierod end when i turn. i am thinking of heating them up and tweaking them,but i am not sure how that will affect them metalurgically. sure as hell don't want them brittle! if i could find one of the arms,i will look into making some billitt ones. do you have a number i can get ahold of you at? thanks.
The lower steering arms are part of the lower ball joint. Have you filled and grinded the casting flash? If you ran a little more spacer would it help?
Can you see exactly where it hits?
i thought they were part of the arms! never really had the frontend apart myself yet! i ground the **** out of the tierod end,but like i said,i wouldn't trust it racing. i have 10mm thick spacers i made on it know,and i am almost into the fenders! i may have to just go to 18's like pauly and make it easy!
why can't you trade the 17x9s on front to 17x8 rims? should solve all that.
heres 17X8 with non adjustable tubular uca's, no spacers...
