Re: Brake upgrades and wheel fitment

Thanks 91CC.
So - 12" PBR's will fit on the rear behind 16" GTA crosslaced rear wheels.
And 13" C4's will fit on the front behind 16" GTA crosslaced front wheels.

I know different wheels have issues and just want to confirm since I don't want to give up my 16" GTA wheels.

Re: Brake upgrades and wheel fitment

I stand corrected the 13's don't fit the crosslace but will fit the formula wheel I have. I guess that leaves you with the 1LE brakes or the 12" C4's up front.

Looking to do the rears right now and the fronts later down the road.
Thanks for getting back.

Re: Brake upgrades and wheel fitment

Question about fitment.... how will the various brake upgrades fit with the stock spares? I was looking at LS1 rear and either LS1 or C5 fronts

Read through this entire thread, and have searched other threads on this board. But most of them seem to refer to aftermarket reproduction wheels and not the original 4th gen 17" SS (ZR1 lookalikes). The closest answer I've found is the above quoted post.

Anyone know for sure if the C5 front brake setup will fit under a set of factory 4th gen SS (zr1 style) wheels?

Would like to pull the trigger but don't want to spend all this $$$ and end up with brakes that don't fit under the wheels I have.

Just about read every thread that comes up when searching the terms "C5" and "Brakes" on this forum.

LS1 FRONT BRAKES CLEAR with a small 1/8 inch spacer.

I am doing the same as you.

Have a low mileage car so I believe I will opt for the 1LE

Re: Brake upgrades and wheel fitment

Hello guys, I'm looking to see if anyone has fit C6 Z06 14" 6pos brakes underneath Devino adana DV430 18x8.5 wheels? I tend to think the diameter will be ok, it's the back spacing that I'm concerned with. Does anyone have a measurement from the face of the hub to the outside of the caliper (the part closest to the wheel)? Thanks in advance for your guys help. Oh, and this is bolting up on my 87 Iroc, or so I hope.

Anybody tried Bassett or Aero 15" circle track wheels with LS1 front/rear combo? Spacers aren't an issue, I have 3" ARP studs...

Re: Brake upgrades and wheel fitment

Will the rear LT1 brakes fit under the firebird 20 slot 15" wheels? And are LT1 and 1LE brakes the same thing?

I think the issue here is gonna be the 15" part. Unless I'm mistaken, 16s to clear ls1, 17s to clear c5, 18s to clear c6

For the ls1 beakes, They should fit fine top to bottom, and I beleive bs as well since They would have the same bs as 4th gen wheels which clear on a 3rd gen... I don't think they will clear c5 top to bottom. I beleive u need 17s for them

No. From a pure radial point of view the LS1 will fit SOME 15's and the other will fit SOME 16's. The catch is the back of spoke to caliper clearance.

Re: Brake upgrades and wheel fitment

Will the LT1 rear disc setup work with 15" Weld racing prostars? (see pic) Rear tire size is 275/50/15 just as an FYI.

Looking at 12" rotor setup from Flynbye performance and just buying the hardware and brackets first then piecing my setup together as money comes in... http://www.flynbye.com/catalog/i182.html

Please let me know as I'm looking to buy soon.

** on another note what other pieces would I need to purchase? Obviously brake lines/ parking brake lines but what else...

Re: Brake upgrades and wheel fitment

Does anyone know if any of the bear brake systems will fit on the stock five spoke aluminum rims on the IROC Z Z28 Camaros? I am pretty sure the smaller sizes will, but what about the larger sizes. Example 13" rotor for the front.

Re: Brake upgrades and wheel fitment

Does anyone know if front Weld RT-S S71 17" wheels will fit over the C5 brake conversion for our cars from BigBrakeUpgrade? I'm LS swapping my 239/244 cam'd LS into my 89 Firebird and I really need the stopping power from the C5 conversion and I'm planning on running 17"x7" Weld RT-S S71 wheels on the front and me and my friends have been wondering if this combo will work cuz I've been told not many wheels fit the C5 conversion... Thanks in advance for any answers
