Help - Ride Height Issue with new Wheels and Tires
I have a 2017 SS Fifty Edition. I just installed a new set of wheels and tires on the car. The new front wheels are 10.5 x 20 (26mm offset) with 285/30/20 tires and rears are 11 x 20 (40mm offset) with 305/30/20 tires. I believe this is a very similar wheel and tire set up to an OEM SS with the 1LE package although my front wheels are .5" wider.
When I put them on the car the fitment seems to be correct...brake and fender clearance is good. However, for some reason the front ride height now appears to be too high. I took a quick measurement and the gap between the front fender and tire is 1" larger than the gap between the rear quarter panel and rear tire. Is this a common issue that you all have seen with Camaro SS owners going from an OEM wheel and tire set up to the 10" or 10.5" front wheels with the 285 width tires? If so perhaps there is a quick fix to get the front end to sit down with the proper gap? I'm assuming it should be the same as the rear which it seemed to be with the OEM wheels and tires. Thanks.

1LE rears are taller than the fronts, sounds about right.
30% of 285 vs 30% of 305 for sidewall height |

Makes sense to me but shouldn't the gap between the top of the tire and the corresponding body panel be consistent front to back? It certainly was when I had the OEM wheels on the car.

You drove/moved the car after putting on the new tires so the suspension could settle, right?

What you can do if you are very disappointed with the gap is lowering springs in the front, or you can just live with it (and maybe buy 275/35/20 tires next time).

GM has the full lowering kit for the car as well, few threads around here on that. |

I think you guys are correct that the size of the front tires are off. The OEM front tires are 245/40/20 with a diameter of 27.7 inches. The 285/30/20 tires have a diameter of 26.7....an inch smaller. That has to be the issue, and it's going to be a problem as I'm sure it will throw off the speedo, odometer, etc. I think I can fit a 275/35/20 tire on the 20 x 10.5 wheels and the diameter of the tires are 27.6...really close to OEM spec.

BMR front springs are great price and fitment. I used them for years
