If I got camber plates and ran ~1.5 degrees w/ ~1/8" toe in for street, when I set it to ~3 deg for autox I'll end up with 1/8 to 1/4" toe out. The owner of the race shop thinks that much toe out is excessive. He thinks I'll get better tire wear and the steering will be better with my current ~2.3 deg camber with zero toe... He said maintaining zero toe is more important than getting more camber so it's best not to use camber plates to change alignment between street and track use. He also thinks the preference for a little toe out is outdated and doesn't apply to most modern cars. So, I was planning on using camber plates and changing camber settings from street to autox/track but now I'm thinking I might follow his advise and leave it static.

I might revisit the idea if I get another vehicle so I don't drive the Camaro as much. Another possibility is running more like 2 deg on the street w/ 1/8 toe in and adding only 1 degree at the track, where I should end up with nearly zero toe or just a tiny bit of toe out... seems like too much $ and effort though!

Adjusting front toe when changing camber is very easy, as long as the camber is changing by a predictable/known amount. I have camber plates marked for street camber and track camber. It's 3 flats on each front tie rod when changing between the two, it is easy to verify with toe plates, I use these- https://www.longacreracing.com/produ...-Magnets-(pair)

More work, but I do think it's possible to mark 2 positions on the toe adjustment and switch between the two.

275/30R19 front and 305/30R19 rear, or 275/35R19 front and 295/35R19 rear, will yield the same/similar F:R split to the OE GY SC3 setup as far as revs. With the 35-series, you a right there in diameter, too. I have a feeling that running tires that are more sticky than the GY SC3 and in a square setup on the SS 1LE has the potential to allow "Ice mode" to become more likely of an occurrence in autox (not necessarily track, though, due to the nature of autox driving). It may also play into the eLSD. Why? Think about what the tire revs/wheel speeds are doing and than think about how the car is probably [optimally] programmed. |

I have just taken delivery of a set of 305/30 fronts and 315/30 rears. I will be mounting them on 19s with stock widths. Any more input on how the 305s respond to being pinched???

I noticed a big difference in tire pressures on the 660's. The sweet spot for me is 30lbs. I ran them for 2 events at 31-32lbs. On the 3rd event I had a decent lead so I tried lowering them. OMG what a difference. Took them to 30 and the front end was noticeably better. Lowered my time by 1.1 seconds. Went to 4th event and ran them at 30 for the whole event and set top pax. I run 19x11, 19x11.5, and 315/30/19 square. Car is roughly 3650lbs.
