These billet wheel adapters let you bolt on rims with different offsets, such as Corvette or 93+ F-body rims. These adapters bolt onto the hub, and your rim then bolts to the adapter. This method of attachment is just as strong as the original bolt-on rim, and much stronger than the slip on spacers. If you need a spacer thicker than 1/2", then these bolt-on adapters are your only choice, other than getting different offset rims.
The adapters are fabricated from a 6.25" diameter billet of 6061-T6 aluminum. The billet is then CNC machined for precise tolerances and a perfect fit. Heavy Duty M12x1.50 studs are pressed into the adapter for a unrivalled strength. Short open ended lugnuts are included with the adapter pair.
82-92 F-body
Maximum Backspacing Front:
5"
Maximum Backspacing Rear: 5.85"
With 2" adapters on the front and rear, both the C4 Corvette and 4th Gen F-body offset rims will bolt right on. We're currently running 17x9.5 front and 17x11 rear ZR1 rims on our twin turbo Iroc-Z, which is the maximum possible without additional fender flares.
Please take a look at our Adapting Rims technical article for
details, theory, and sizing information.
Custom Adapters and
Applications
We can custom machine any size adapter needed, to adapt nearly any
wheel to your machine. They can range from 1" to
4" thick. The custom adapters take 10 days to
machine, and can have inch or metric HD studs. You will need to specify
the thickness needed, as well as both the hub and rim bolt circles. All
specifications must be known for us to make them. Custom adapters
are not returnable, so please double check your measurements.
You now have new rims with a different number of studs?
To adapt wheels with a different amount of lugs (a
five lug rim to a 4 lug hub) will require a two-piece adapter. The base is
machined to fit your hub. The second half (the hat) is machined for your
rims, and is bolted to the base with countersunk screws. All heavy duty
hardware is included with the adapters so strength is not
compromised.
