Chevrolet SS 19x9 rear wheels all around

Post by Toddie23 » Fri Jan 15, 2021 2:26 pm

I found a shop that has (4) 19x9 rear 2014 Chevrolet SS wheels for sale. I have a 2013 9C1. What fitment issues will I have with the 19x9 wheels up front? And what size spacer if needed up front? I have looked thru past post with no luck.

You don't mention what brakes you have on the car - stock or Brembo? If Brembo, front 4 or 6 piston?

As a point of reference, I'm running an 18x9 wheel with +47mm offset. Also running Brembo 4-piston front calipers. On front only, I do use a 2.5mm hub centric spacer because my particular wheel design runs extremely close to the front face of the caliper, and as the wheel is not OEM, I wanted the hub centering function.

The SS rear wheel is +57mm offset - to match what I'm using would call for a minimum 10mm spacer at the front - and probably longer studs or ET (extended thread) lug nuts, to keep adequate thread contact for torquing to spec.

I believe there are a few SS owners using 15mm spacers, or possibly adapters - spacers at 15mm would require longer wheel studs, which entails a bit more effort. The OE wheel contour (back of spokes) should be plentiful if you used a 12mm spacer and ET lug nuts - and not have to change wheel studs.

The holes in a spacer will need to be large enough to let the extended shank of the ET lugs "engage" in the spacer - it should be a close fit.

Custom spacers - I recommend Motorsport Tech in Reno NV. https://www.motorsport-tech.com/special ... p_car.html

Whatever you do, thread engagement on an M14 stud needs to be 7 to 8 turns, minimum.
