Attention- 2002 ZL1 owners...rear wheel fitment.

[GRB]

We found today that the rear 18x10 Fikse Profil 10 wheels which were ordered for a camaro are not hub centric on these ZL1 modified axles. The acorn nut only fastens the wheel via the 5 acorn recesses. Fikse says the wheels should have been ordered for a Z06 rather than a camaro. They suggest Prestige Wheel for hub centric adaptors. The current set-up on my car is not NHRA legal and with 700HP not safe. I am not blaming anybody for this but I would swear I mentioned to Fikse that these wheels were going on a camaro with Z06 brakes. Maybe not. The fronts fit fine.

Anybody else have this problem? If so what did you do? Thanks.

BTW - it appears there was a spacer installed at the axle flange to clear the wider Z06 disc. This is what causes the hub not to fit snugly to the axle. The back of the Fikse is tapered and for this application should not be. I've got a call in to Matt to see what he knows.

GRB,

Not sure what problems you are having with the wheels on your car, but the rear Vette brakes do not interfer with either Camaro, Corvette or Fikse wheels on your factory rear axle. As far as what we did to adapt the Vette brakes to the rear of the Camaro . . . we had to make new spacers to relocate the emergency brake setup 1/2" further out to fit with the Corvette Rotors. The location and fit of the rear axles are stock and the Vette rotors are stock thickness.

We have Matt Berger's ZL1 here with the Profil 10 Fikse wheels on it and no problem with fitting the rears on ZL1 modified rear axle. Did you put a 12 bolt rear end in your car ?? and if so, what brand ??

I am really puzzled as to what you are talking about here. Can you supply us with some digital photos to show us what your problem is ??

I am very surprised that Fikse would recommend you to buy anything from an outside source when they can sell you wheel spacers that have the axle hub in any size you want.

You better give Lamar credit for his motor or he might be upset . . . [img]/ubbthreads/images/graemlins/beers.gif[/img] Bring it over when you guys get it finished. It should be an animal . . . [img]/ubbthreads/images/graemlins/flag.gif[/img]

Matt, it's Ray. I left my number on your pager today. I called Fikse and talked to the guy I bought my 8 wheels from after I called you. He acted a little surprised because I told him what kind of car they were going on and am almost positive I told him about the Z06 brakes originaly. Oddly enough I had a message on my mobile phone a few hours later saying he had what I needed and would send them to me.

Damned if I know what all this means. All I know is from 30+ years in the wheel and tire biz the way the wheels were fastened to the hubs/axles wasn't going to hold up to what Lamar is building. I just don't want to loose a wheel power shifting at 120mph or so. Not to mention the fact that the present set-up would never take a hard launch on racing slicks. BTW - the car and complete motor build up will start in a 5 or 6 part series in one of the car mags in Feb. I'd say more but I'm sworn to secrecy. Call me when you get a chance.

Ray,

The front Z06 Brakes are different in size compared to the stock Z28 brakes. You will need at least 17" (18" fit fine) and a correct wheel offset or a spacer to fit onto the new Vette front brakes.

The rear Vette brakes are so similar to the Camaro brakes . . . that they are not worth mentioning to any wheel supplier. The Vette rotors are the same size in diameter; but, they are vented where the Camaro rotors are not, they weigh 3 pounds lighter than the Camaro rotors, and they look different. I was told that we didn't need to change them because they were not worth the hassle to make them fit; but, for those three reasons and the fact that we said that the ZL1's had Corvette brakes is why we went to the trouble to replace them for little gain.

Matt, It seems there is a bevel inside the wheel hub that is causing the inside of the wheel center not to contact the end of the axle housing. Both your rear end and the Moser replacement are identical in that respect. Fikse is evidently aware of the problem so we should have this issue resolved today. Whatever happened to that little blue Chev. II (?) you had? And if you start modifying SS Silverados let me know. Mine could use another 100 ponies. Ray

Mike, Mike, don't throw stones my friend. Are you the one who left my driveshaft loose? Or certain connections unconnected? I'll stop there. Let's bet my paycheck against yours on the 700hp. At the crank.

Anybody else smell the sour grapes?? [img]/ubbthreads/images/graemlins/haha.gif[/img]
