Pete,
Thinking about hitting the autox scene again. As I'm sure you are aware theres a lot of changes coming down that opens up all kinds of things for 5th gens. A 200 tread wear tire and the ability to step down 1" in tire diameter can level the playing field between the 5th gens and others. That said, most of my experience has been with 4th gen corvettes and a square setup. Looking at the aggressive FE4 specs would the car understeer quite a bit? Assume a staggered setup. Only reason I ask is because I hate understeer worse than anything. What do you think of this set up for a 13 SS non 1LE on a staggered set up: Front: max castor, 1.5neg camber, .25 TOTAL toe out rear: .75 neg camber, .25 TOTAL toe in. I like the darty, quick turn in and don't mind if it tracks grooves a little bit on the road. I'm just trying to get a handle on how these cars react to alignment changes vs what I'm used to.

Front Camber Max Out Negative Camber. You'll have to check the clearance between the strut-coil-sidewall. You can relive the OEM strut clevis slot to gain more negative camber -1.25 is minimum for AC. Front Caster increase to the limit available based on ride height. The lower the car sits, the lower the caster number will be. You can use the OEM eccentrics for rear camber adjustment for caster after the hole is ground out to a slot. Front Toe we want out, a lot -0.50 per side total -1.00 These front specs will increase tire wear. Rear Toe should be IN +0.12 per side Rear Total Toe IN -0.24 Rear Camber, less is better. The closer to 0.00 you can get the better. These rear alignment specs IMPROVE rear tire wear. These front and rear setting will improve turn in and reduce understeer. |

WOW, that is a lot of toe out in front.
I'm tracking what you're saying about the front vs rear on camber though. I was thinking that even .75 neg might be pretty aggressive for the rear based on 1.5 neg front. I think I'm gonna go with -.5 rear camber -1.5 front camber max castor Keep the toe at .25 total front out/rear in. I may play with this at the track though once I figure out what one revolution on the tie rod equates to in toe in/out. I can always dial it in/out for the track once I figure this out.

Anyone have a diagram of exactly how much material, if any, is specified from the shop manual as safe to remove for alignment purposes, specifically front camber and caster?

Pete, I have put a more aggressive alignment in the car for autocross and HPDE's. What do you think of these specs, I am a little worried that I have to much rear toe at 0.31*:

Hey everyone, quick question! I have a 2013 1SS (non 1LE) with NPP, headers/intake, 20x10 Front and 20x10.5 Rear wheels with 275/40/20 Tires STOCK SUSPENSION... What is the best alignment to run if I plan on tracking the car once or twice, but will be driving it on the street most of the time.
Thanks! |

Why did you go so positive on the rear camber, or did they not adjust that?
It looks like the before measurements were made before the lift was set on the locks (level) and just the toe was adjusted. |
