A Chevrolet Corvette C8 (from 2020) uses a 5x120 PCD and a centre bore of 66.9 mm.
Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.
Centre bore: the wheel must have a centre bore of 66.9 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 66.9 mm.
Offset: the original is ET54. Compare your future wheel with the offset calculator (your vehicle is already selected) to see how many millimetres further in or out it will sit.
Fixings: thread Ecrous - 14x1.50, tightened to 190 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Tyres: original fitment is 245/35R19. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).
Vehicles with the same PCD and centre bore
Same 5x120 PCD and same 66.9 mm centre bore: wheels from these vehicles bolt on and centre on a Chevrolet Corvette C8 without rings. Offset, width, diameter and caliper clearance still need checking.
These vehicles also use 5x120 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 66.9 mm, and will not fit if it is smaller.
A Chevrolet Corvette C8 (from 2020) has a PCD of 5x120: 5 studs or bolts spaced around a circle 120 mm in diameter.
Does a Chevrolet Corvette C8 need a hub centric ring?
The centre bore (hub diameter) of a Chevrolet Corvette C8 is 66.9 mm. A wheel with a larger centre bore is fitted with a hub centric ring that brings it down to the hub diameter. A wheel with a smaller centre bore cannot be fitted.
What offset (ET) for a Chevrolet Corvette C8?
The recorded original offset is ET54. A lower ET pushes the wheel outwards, a higher ET pulls it inwards: check wheel well and caliper clearance before making any change.
What tightening torque for the wheels of a Chevrolet Corvette C8?
The specified tightening torque is 190 Nm for Ecrous - 14x1.50 fixings. Tighten in a criss-cross pattern with a torque wrench and check the tightness again after about fifty kilometres.
Which vehicles have the same PCD as a Chevrolet Corvette C8?
With the same PCD (5x120) and the same centre bore (66.9 mm), these include: Buick Envision, Cadillac CT5, Cadillac CT5-V, Cadillac CT6-V. Offset, width and rim diameter still need checking for each vehicle.
