Will stock Corvette C5 wheels fit on a 4th gen? I am looking at both the polished thin spokes and Z06 wheels. I have seen anything from 17x8.5 for the fronts to 18x9.5 and 18x10.5's for the rear. Will thses bolt right up to a 98 Camaro?

 

yes and no. You gotta check the offset of the C5 rims you want. i have Z06 rims 18"x10.5 rears with a56mm offset. I had to notch teh bumpstops and use a BFH on a few spots on the inner fender. I also am running 295/35/18 firehawk tires. Fronts are 17x9.5 with 275's.

Wheel Fitments

The numbers in the columns are as follows:

WIDTH ..... OFFSET ......... WIDTH OF TIRE

7.5" ..... +35 to +45 mm .... 215, 225, 235
8.0" ..... +38 to +55 mm .... 225, 235, 245
8.5" ..... +38 to +45 mm .... 235, 245, 255
9.0" ..... +38 to +56 mm .... 255, 265, 275
9.5" ..... +38 to +56 mm .... 255, 265, 275, 285

11.0" ... +45 to +56 mm .... 305, 315, 335

NOTE: 315 series tires DO NOT fit 9" or 9.5" wheels. It will not be discussed any thread posting will be edited, locked or deleted.

PLEASE READ @ 315's

Z06 Corvette Replicas:

17"x9.5" +50 to +56 mm no problems. 275/40R17.

18"x9.5" +50 to +56 mm 275/35R18 or 285/35R18.

18"x10.5" +50 to +53 mm. Higher than 53 mm will require the BFH mod. 285/35R18s thru 315/30R18. Over 295 may require rolling the fenderlip and will need the BFH. +58 mm is the typical available offset for the Z06 replica, which will require a little BFH and/or a small spacer.

Y2k Corvette Replicas:

17"x8.5" +56 mm

17"x9.5" +50 to +56 mm

18"x9.5" +50 to +56 mm

17"x11" Wheels

ZR-1 Style for Camaro +50 mm (Known as Grand Sport offset)
ZR-1 Style fo Firebird +36 or +50 mm The wheel well on the "bird" is a little wider.

American Racing TT-2's +45 mm

With 17"x11"s there is always a possibility of needing the BFH and/or fender rolling mods with 315s. If lowered, an Adjustable Panhard Bar becomes a virtual necessity. Some have used the +38 offsets with an 11" wheel but it does stick outside the fender and is definitly not recommended on lowered vehicles. +50 and +56 are the two most common. +50 is the better fit (for the ZR-1 replica).

For road race only applications a 17"x11" at all four corners can be made to fit.

 

The OEM C5 wheels varied slightly by year. All the fronts were 17 x 8.5" 56mm offset. Will work on the 4th Gen F-Body. Just sits a bit deep in the wheel well.

The rears were either 18 x 9.5" 56mm (97-99) or 18 x 9.5" 65mm (00-up). Both those will fit in the rear of a 4th Gen with no problems. Again, they will sit fairly deep in the wheel well.

As noted in the previous post, the OEM C5 Z06 rear 18 x 10.5" 58mm offset wheels present pretty much the same problems as the 17 x 11" 50mm offset wheels, and they are discussed in the Wheel and Tire FAQ stickied at the top of the page.

C5 Z06 fronts are 17 x 9.5" 56mm offset, and fit with no problems at all.

Aftermarket copies can have offsets varying all over the place.

 

First of all yes I read the faq

My question is similar to this one so I thought I'd add mine :

I'm looking into buying a set of 56 mm offset 18x11 c5 wheels for the rear of my WS6 , (I know about needing a fender roll/adjustibal panhard and the BFH mod... Maybe a small shim? The wheels have 335/30r18 mounted on them. My WS6 is on strano lowering springs ...

Will I have any more problems with a 335 than with a 315 ....will the difference in diameter cause any speedo problems ?

Just couldn't find much info on people running this size tire?


Thanks in advance guys

 

I just read the FAQ on the wheelss sticky and it seems that the 17x11 and 18x10.5 C5Z wheels are the same in fitment on a 4th gen?

If so then in most cases these should not present much of an issue - maybe a small 1/8" spacer could solve?

 

The backspace is similar, so the problems with the inside edge of the tire rubbing on the inner fender liner, and the possibility of the edge of the rim catching on the bump stop bracket are identical. But since the 10.5" wheel is narrower, it does offer the possibility of moving the wheel outward with a spacer of up to 1/2" while still keeping the outer edge of the tire under the outside edge of the fender.

Adding spacers to the rear wheels present problems with the stock stud length and strength.
