Brake upgrades and wheel fitment

[70's iron]

Does anybody knows about the 15x7 Turbo-Cast wheels ? I'm on the way to buy a set, and wanna upgrade my 4-disc 83 T/A with a stock appearance...

Just like a sleeper. : )

It would seem that the "Ghetto-gold" 15" cross lace wheel can only accomodate the LS-1 in the front. What options, if any, are there to improve or equalize the rear braking capabilities so they'll better match up with the front LS-1 upgrade?

so will LT1 Front brakes fit on a third gen, i have 19" rims so space is not a problem.

A little late but no they won't, the LT1s are a different design than our stock front brakes.

LS1s can fit under 15" rear wheels with some grinding, I don't recommend it.

C5s will not clear TT2 wheels but a LS1 setup using a C5/C6 base caliper will:

I have 18" Z06 rims 9.5 front 10.5 rear and id like to put C5 Z06 brakes in the front and I was wondering if they would fit. Now the dilemma I have a 91 Z-28 with the drums in the back and whats the best back rear discs I can use.

Considering the factory Z06 front wheel was 17", and you have the same ones in 18", I would say so.

This just in folks, I put my 15" centerline convo's on my LS1 rear. With ZERO modifications they fit. Its sorta snug, it only gives me 1/4" or so of clearance, but hey, most supercars are under 5mm, so yeah....

I have a question concerning the fitment of 1991-92 Ronal R15 Firehawk 17 inch wheels. Will they fit with the C5 13" brakes?
Thanks for any help.

What brake setups do fit stock 15" rims? I'm looking at upgraded calipers up front and from this thread it doesn't look like I have many options.

[ebmiller88]

Pretty much 1LEs and 12" C4s, your wheels are the limiting factor.

Nope, even LS1s are pushing it in those wheels. They have a good amount of taper from rear to front and this is the issue.

No, C5s will not clear stock 16" wheels. You can fit full 13" C4 HDs in them as well as a LS1 kit using a C5 caliper, no problem.

Ed, will an LS1 kit fit a smaller rim (internally) than a C4HD set up? I have a set of light weight stamped aluminum rims that are just a hair too small for a C4HD kit.

[91CCFirebird]

Will the C4 HD set-up fit under stock 16 inch formula wheels or will only the standard C4 brakes work?

[iansane]

Didn't see it in this thread anywhere.

14" C6 Z06 rotors/6 pot calipers will fit behind a base 18" c6 wheel with the proper ~2-2.5" spacer required to get those wheels to fit on our cars anyways.

I upgraded to the 1LE front brakes several years ago and they have been outstanding at the track all of these years. Of course the aggressive Hawk pads I run in them is what does all the work.

And with the 'R' compound tires wrapped around the 16" GTA crosslaced wheels, classic.

[HP52TA]

Will LS1 rear brakes clear the 16" crosslaced wheels without issues?
