Track alignment
Just got a 2007 c6 z06 with 30k miles. It hads heads and cam around 550whp. I just bought a set of ccw c10s, a set of toyo r888s and full fluid flush of every fluid in the car mainly from amsoil, some other products used for brakes etc. But, with my first track day march 8th i want to get a track alignment done. Guys at Phoenix performance seem legit and look like they have a good background they suggested -2.0 camber in front -1.5 in rear and adjustable end links for around 750-850$ with corner balancing. Price isnt horrible but looking if anyone else has any other guys in Jersey/PA/NY.
My main question is, my 18x10 and 18x13 ccws i will be getting the entire alignment done with them on as they are my track wheels. Now when i drive around town and out to dinners or road trips ill have my stockers on which are 18x9.5? in front and 19x12? (Not 100% sure on widths) but, how will this track alignment affect a different wheel size. Is it dangerous for suspension components? Excessive tire wear i assume? Not sure, do people get another alognment after track days for stock sizes and do that every time, no way! Has to be some solution or middle ground i guess. Any help is appreciated!

I have an 08 Z06 on CCW's with R888! ;D 18x11 18x13 295/ 335 18"
I rock way way more aggressive settings than you, and uniballs, I did 3000km to germany, then austria, a few days on the nurburgring, and horrible rain etc on pilot super sports on stock z06 wheels. Just gotto go slow on rain, and it will wear the inners, and you have to be careful on rain.

Optimum camber for you on the track will probably be a matter of trial and error, but -2/-1.5 is probably a good place to start. Might need a little more in the F, depending on the track and how hard you push the car.
Any street/track dual purpose alignment will be a compromise. Enough neg camber for the track is too much for the street, and a typical track alignment would feature a little F toe out to help with turn-in.
Tires are generally more forgiving of camber than they are of toe...
"Just enough" neg camber for the track will lengthen tire life there, and only slightly compromises street tire life. It's a good trade off.
"A little" front toe out to help with the car cut is of minor benefit on the track, but will shred the tires on the street. Not a good compromise, IMO.
Zero, or a breath of F toe in, and for sure run toe in at the rear for stability.
Different tire/wheel combinations might make the car feel different... excess neg camber can reduce the straight-line contact patch enough to compromise braking. Shouldn't be an issue, but maybe feel it out with the street tires ahead of time.

great! Thanks a ton, as i talked with the shop whos doing alignment he recommended a street/track setup. So recommending the specs he did i should he fine with both then i believe, at least a little better on track than stock alignment. As long as when i put street wheels on im not hurting my suspension or endangering my street driving, ill be alright. Thanks a ton
