: Fyi: C5 Z06 Replica Rears and Drag Radials

Just to let you know. My V coupe will need spacers to clear my calipers. Without spacers, they contact the leading/trailing ends. I actually shaved some paint off when rotating the wheel to check. Up in the air, the rear section of the wheel didn't contact the lower control arm. I never dropped it on the ground to check clearance because it was clear they wouldn't work anyway.

Are the replica wheels 10.5? I have not heard to date of the C5 Z06 wheels hitting calipers, only shock perch. I wonder if the offset on your replicas are identical to the OEM wheels.

Are you good to go on where to get the spacers?

Mine hit the caliper without a spacer also.

Just for reference, where does one pick up the spacers? I am guessing they are a hubcentric design?

Mine are from pep boys. The lugs center the wheel since the are tapered on the threaded side.

Yep, 10.5. And I ordered a set of 1/4" spacers from Summit. Our races are held during the first weekend of every month, so I should be good to go.

I used spacers initially then recently went to the shock perch grind. Thanks to blumachine.

This is a pic of my grind job. I removed a little more material than most people. Sorry if the pic is bad but it is from my blackberry at the track today.

Was this known? I never read about it. I did read about C5 Z06 rears needed clearance work to the lower arm in order to fit without spacers. I also read that the lower arm didn't require cutting back if a spacer was used. I read that C6 Z06 fronts were a direct bolt on (not requiring spacer or cutting). I did read that replicas were heavier, but nothing about them requiring a spacer.

unbeknownst to me that c5 z06 replicas would not clear calipers without spacer

Yeah, that's why I posted this. Just wanted to get it out there. Rabbit made it sound like everyone knew. I kinda felt stupid for a little while.

Aha, missed the key part before: replicas. If I have OEM(Alcoas too, FTW!) then I shouldn't need spacers?

I can't remember if the ones stamped GM are Alcoas or not. Mine are stamped GM. Only on the passenger side was a spacer required.
I got a tiny tiny tiny tiny rub when I launched in the neighborhood. So I got the 1/4 spacers. The next year I said, "Forget the spacers" and did the grind. I'll tell ya what, if you want, I'll send you my spacers so you'll have em if you need em. PM me with your address.

Now stop your damn whinning. :)

I know this:

01 C5 Z06 are Alcoas
02-04 C5 Z06 Speedline

Alcoas are forged and marginally heavier
Speedlines are spuncast

Speedline is stamped on the back of the wheel.

I do remember there was an ITALY stamp on the back of mine as well.

I will check mine when I get home.

Speedline is an Italian company.

Mine must be speedline.

Here is a tidbit thread with a post from Tbss ( I recognized the M3 pic)

Weights for these wheels are as follows:
19.6 lbs, front; 21.4 lbs, rear - 01 Z06 Alcoas
19.2 lbs, front; 21 lbs, rear - 02-04 Z06 Speedlines


LOL............

I still do not know the answer to your question about the spacers.

I'll get the bare wheels on my V for a test fit in the next day or two.

I've got 1/4 inch spacers that are tried and proven, if you need em.
Let me know.

Yup mine needed 1/4" spacer to clear, replicas. Slight vibration but its fine, i would like a nicer spacer setup and i feel like it would get rid of the vibration

Oh, and thank you! I'll let you know after I test fit them...

Same wheels I just knotched the arms with a grinder, so it would not make contact.
Don't need my spacers now. If you do not have a problem with grinding the arm, I prefer this route, especially if you are racing.
Your lug nuts will grab more thread.

Also, do not forget to zip tie your ebrake cable, it will rub the rim otherwise.

Thanks, very nice and better than running spacers.

Anyone has pics of these wheels installed on the V ??

Oh Curtis...

Put the Z06 rims on tonight and they don't rub. Technically. However, the space is SOOOOOO tight, the outboard wheel weight that was currently on the wheel would ever so lightly scrape. So I was wondering if you could send me those spacers.

Sounds exactly like the fittment I had.

Pm me with your contact information and I will send them right away.

Anywho, just got off the phone w/ Jegs to order the Mickey Thompsons and I should have everything set up by the end of the week. Will be at the strip in Rockingham, NC next week with the SHO guys...Frackin' Jegs!

I called on Monday and they said they'd be there by Wednesday. I figured Thursday would be fine. When they didn't show up yesterday I was concerned. So I called them today and they have no record of the transaction. Nothing. Stupid me, I couldn't find the confirmation number. They said my CC wasn't charged and it wasn't. But no DRs. And it's too late to get them now as I leave for the SHO Convention on Sunday morning. And even though I could have them shipped somewhere down there, I don't want to have to coordinate that and then have to get them mounted down there somewhere.

Ah well, it was going to be in the high 90s next Thursday so the times wouldn't be best. Guess I'll just have fun and burn up the Hankooks a little. sumbitch!

I looked at the Mr. Gasket ones as well. I ended up buying the ones below.
Either will serve the purpose, I suppose.
One trick I should tell you, (courtesy of Dr. Buzz) is to rheem the holes a little so there is a tad bit more room, otherwise you'll have a heck of a time getting them off (At least that is the case with this set).


Part Number 65050

Don't forget to tie the Ebrake cables away from the rims......
