can it be done? i know that for c5's there are bogart and ccw "drag packs" that are $$$, and clear the front rotors, and draglites will "work", but i believe that is after putting c5 rear brakes on the front. all the above info is without spacers, i currently have c5 brakes, and rims that have 1.5" or 2" spacers on them, so could i get some skinnies that would clear my brakes with these spacers, and still ahve the skinnies be wide enough for mild street driving?

I was working on trying to fit C4 or maybe it was C5 brakes on my car and they wouldn't fit with skinnies. Using spacers, I would have had to push the wheels out about 2" to clear the calipers. Large rotors and the large multi piston calipers are designed for 16+" wheels.

I ended up just putting an Aerospace front brake package on the car.

i have skinny with my ls1 front brake....with 2" spacer its about 1" out of the fender....rims are 15x4




doesn't look that bad, but i dont roll them in the street, there is so many pothole over here.

here's a mockup picture to check clearances (before i bought new calipers/pads) with my ls1 brakes and a billet specialties street lite wheel. this wheel is very inexpensive for a billet wheel. 15x4 with a 1 5/8" backspacing and a 1/4" thick spacer.



you can see in this picture how the wheels sit in the well, perfect if you ask me

This is exactly what I'm attempting. The 15" wheel diameter fits over the caliper, but has just about no clearance probably in the range of 1/16". The Summit street star wheels I have need at least 3/4" spacers to move the spokes away enough, but I'm thinking I'm most likely going to get 1.5" spacers that should also let me fit wheels from an LS1/C5/C6. I haven't totally studied it, but I'm thinking some grinding on the caliper abutment will let me bring it towards the center of the spindle for more clearance.



SebasIroc: Might want to check for tire clearance. It looked to me like a 2" spacer would have the tire swinging into the front and rear of the wheel well with the new arc it makes.

easy solution is GTO spares for 50 a piece and run M&H 17 inch front runners

thats what i'm gonna run with my C5 brakes

thanks fast, I will check for tire clearance when spring is back, never really feel any rub, but never had to do tight turn....since they are only on at the track.

wow, i couldnt have asked for better responses! m66nova, i love those wheels, but i perfer prostars for the look im going for, do you think they have the same dimensions with a different design one the face of the wheel? and how are skinnies for street driving? i dont want to make my car useless on the street.

mw66nova

they have a completely different style of joining the center section with the rim portion of the wheel. i have much much much more clearance than the pro-stars.

as far as the drivability is concerned, i'll let you know in about a month as i don't have the motor in the car yet.

fast82z - you could easily grind the cooling fins down on the calipers for more clearance. It's not like you're going road racing on the skinnies anytime soon.

As Matt stated, the billet wheels have a lot more room out by the wheel lip due to their construction vs. a cast/forged wheel.

I'm glad to have seen this (actually saw it on YB first). I was hoping to be able to run a bit larger brakes and still fit skinnies on the hard tp I'm putting together. For those with forged wheels you could probably run regular/non-GS C4 vette rotors(or 1LE and not have to turn stockers down to hubs) and C4 vette calipers. 12" brakes and twin pot calipers would still be a considerable improvement, but less likely to have clearance issues.

The fins aren't where the issue is. The spoke area on the outer part of the caliper is why I need the spacer, and the smallest outer diameter of the caliper is just really close to the wheel.

Shagwell

Gotcha - don't really see that in the pic, but it makes sense. - Don't the 4th gen guys have to run spacers to fit forged skinnies? It would then makes sense that we would have to to run the same brakes.

Fast82Z, did you ever decide on a spacer size?
I have the same wheels w/C5 rotors and calipers.

I bought 1.5" spacers to use there, but like I said a 1" spacer looked to be plenty. I ended up going with LS1 rotors because I changed my mind and am using the stock 15" Z28 wheels instead of the skinnies. Might I add, the LS1 brakes all around are great compaired to the stock front disk and rear drum setup.

brutustitan

What brand spacers are they and how much$$ ?

well this thread just answered alot of question that i had about ls1 front brakes. just wanted to know who turned down your stock rotors, that way i can get working on it.

Shagwell

Any machine shop/machinist with a lathe can turn them down. It's a fairly simple job.

my ls1 front brakes clear my pro stars with just a 1/4 inch spacer.

I just got some ebay spacers. They were a pair for about $60. There's better ones out there that maintain a hub centric fit, but these seemed just fine.

cool man i thought i would have to fond someone with one of those brake turning lathes to cut the discs off. i have a buddy with a lathe and we have dicussed doing it but we were not real sure of a good way of chucking it to the drive head. if by chance you got to watch yours get turned, i would like to know if you remember how they chucked them to the lathe.

Shagwell

He chucked it from the inside and cut about 1/2 in from either side on the spindle section of the hub; just enough to create a sqaure/flat section on the outside to properly chuck them. Then he just started cutting. They not only need the discs cut off, they also need to be turned down a bit for the rotors to seat properly.

thanks man, i may have to go get some ls1 rotors and give my stockers the cut
