Alignment, V710s: lets talk
 
Posted this in the suspension/tires section, but I think I might get a better response here:

Just in time for the upcoming ProSolo and Divisionals, I lucked into some 225/45/17 V710s. They are going on a FC with Koni Yellows (stock valving), 375/275 (will go a bit higher at some point, like 450/350) GCs, and stock sways for the moment. The car is going to get aligned next week. What settings do these things tend to like? I have a ton of front camber since I installed the suspension, should I keep it at like 2 deg or so? Any other things to worry about like toe? I think the car is gonna push like crazy on this setup, so I'd like to get it a bit more tail happy for killing cones

I was reading that I don't need to worry much about keeping them cool (I always hosed my Azenis off between runs), and that I should keep the pressures low, like 30 or 32 psi cold if the car is stiffly sprung. I know it is gonna be a big switch from street tires, but I want to make it as painless as possible so I can concentrate on learning to drive on r-comps.

Any thoughts guys? Only street miles are driving to events.

I hope you have the camber caster plates. I would set up for a lot of camber (-3.5 to -4) and a slight toe-out (-0.05 to -0.20). In the rear, keep it between -1.0 and -1.5, with toe between 0 to toe-in of 0.15.

I do have both, but only for the front.

4 degrees!? Seriously? Is that to try to compensate for the spring rates?

been a long time since we ran v710's, but 31-32 psi should be HOT.

It's the fact that FC's suck for camber gain while cornering. Set it up at 3.5 first, and use a tire pyrometer to figure out if you need more or less.

I have rear camber aids for sale if you want. Both the subframe adjuster and the individual links.

I'll also be in Albany this weekend, if you want to arrange a pickup.

Might have to take you up on the links, but I won't be able to meet this weekend.

Looks like I'm gonna need to buy a pyrometer too.
