For anyone else trying to run steel wheels here's what I did:
- 4 Camaro steelies from FB marketplace (Look on FB marketplace, mine were $100)
- 2x5mm spacer
- 2x3mm spacer
- TPMS sensors + Tool off Amazon (~$60 + $10)
245/50R18 Snow tires (225/55R18 will also work, 235/50R18 will be slightly smaller)
Mounting the wheels at the front it tight so I went with a 3mm spacer(2mm should work too but 3mm was easier to find).
without spacer:
Front struct clearance is fine:
For the rear you must run a 5mm spacer otherwise the caliper will get damaged. I've driven the car for over a month now and I haven't had any issues with rubbing.
