Putting C6 Corvette Wheels on Your 4th Generation Camaro/Firebird
I’ll put all the technical stuff up front for those of you looking for the details you need to know for this wheel and tire combination.
Summary: This is a set of OEM C6 Corvette Wheels on a 4thGeneration Camaro. The rears are 19×10” (+79mm offset) and require a 1.25” adapter to compensate for the deep offset on them. The fronts are 18×8.5” (+56mm offset) and are a direct bolt-on.
Wheels: C6 Corvette Wheels span from 2005-2012 and came in several designs and finishes. Note that the Standard-C6 and Z51-C6 wheels are the most common, as well as easiest and the most popular, for swapping onto older vehicles. C6 Z06, ZR1, and Grand Sport wheels are larger, and more difficult to swap. (See dimension chart below for all C4, C5, and C6 Corvette wheels.) This article and pictures cover the Standard-C6 and Z51-C6 wheels.
Camaro: The 4th Generation Camaro/Firebird spans from 1993-2002 and regardless of the model, whether V6 or Z28 or SS, Formula or Trans Am, the bolt pattern and track width of the car are the same, so the information here applies to all F-Bodies of these years. *see note below regarding variations in hub diameter sizes.
Adapters: Both the Camaro and the Corvette use a 4.75” bolt circle with 5 mounting bolts. The rear Corvette wheels require a 1.25” adapter to fit the Camaro. Be certain that you get adapters that have the center hole machined to fit the hub on your axle flange. The adapters are very simple: They bolt to your existing wheel studs, and have a 2nd set of studs which you then bolt your wheel to. You can find these on ebay for as little as $50. Buy American made parts, folks!
Note on Axle Hub and Wheel Bore Sizes: Factory ’93-’96 Camaro/Firebird rear axles have a 70.75mm center hub diameter. C6 Corvette wheels have a 70.5mm diameter hub bore. It is important to get adapters which will fit over your rear 70.75mm hub if you have a ’93-’96 car, and also accommodate the 70.5mm hub bore of the C6 wheels. This is also important if you choose to take the optional step (outlined below) of putting adapters on the front.
Tires: These photos show 295/30-19’s on the rear wheels and 255/40-18’s on the fronts. Both of these tire sizes calculate to a 26.00” diameter in spite of the staggered 18/19” wheel sizes.
Speedometer: Base Camaros were programmed for 26.17” diameter tires, while Camaros with Z-rated tires were programmed for a 25.66” tire diameter. With the 26.00” tire diameters above, you’ll need to reprogram your computer for speedometer accuracy. This will only affect your speedometer, not engine performance, so if you can’t reprogram right away just remember that your speedometer is a little off. With larger diameter tires, you’re going a little faster than your speedometer indicates.
Optional Front Adapters: After driving the car for a couple of years with the C6 wheels, I decided that I wanted the front track width of the car to match the rear. This is mostly a cosmetic preference… although I believe it also handles a little better with the matching front/rear track widths. It tended to understeer a little with the front wheels tucked in narrower than the rears. I put a set of 1.25” adapters on the front to match the rear, and I prefer the looks of the car this way. The front wheels fill out the fender wells better, and the wheels show more when looking down the side of the car. As stated above, the front wheels will fit and function just fine without adapters.
Lowering: When I initially put the C6 wheels on this car, and wrote this article, the car was stock height. Since then, I have lowered the car 1.5” and added the 1.25” adapters to the front wheels as mentioned above. The front wheels never rub at all. The rear wheels rubbed badly after lowering the car, and I finally had to roll my rear fender wells. My advice is that you should expect to roll your rear fender wells if you plan to run the 19×10” C6 rear wheels under a lowered Camaro/Firebird. It is more than nuisance rubbing… it was cutting through my sidewalls. The 3 pictures here are with the car lowered 1.5″ and the front wheels using the optional 1.25″ adapters.
My Personal Take: I really wanted GM wheels for various reasons, and the style of these wheels is very similar to the stock SS wheels. I thought over various styles and colors, as even this wheel design is available in silver painted, polished aluminum, and chrome, stock on the Corvettes. This set is the polished aluminum variety. With the car now lowered and with matching front and rear track widths, it now looks very ‘low and wide’, especially when viewed directly from the front or rear!
