10mm AKA (3/8") Or 12mm AKA (1/2") Wheel Spacers 1984-2019 Corvette C4, C5, C6, C7 5x4.75 (5x120.7) Slip On Hub Centric With Extended Thread Lug Nuts Included! 70.3 Center Bore & 12x1.5 Lugs Included
Used these on my 2006 C6 base hatchback Corvette. I powder coated the stock wheels black and grabbed the black lug nuts to match, and got the spacers just to help fill out the wheel wells a bit and make the stance a little less tucked.
Came in very well packaged, so nothing arrived damaged or scuffed. The extended thread lug nuts look great and the finish on them is excellent. The spacers themselves are solid and clearly machined perfectly — no wobble, no play. They slid right onto the hub and locked into the existing wheel hub without any fuss, nice and hub-centric like advertised. Overall a very solidly made kit and I'd buy from this seller again.
