2015 SCCA Wilmington Championship Tour
 
Wilmington Champ Tour is coming up in a few weeks? I'll be there. Who else is going?

I'll be there in ASP.

Hey I know we'll be racing each other, but what alignment setup do you have?

Details here on mine.

Nice, your car seems to favor a lot of oversteer in those slaloms. What size tires and pressure were you running?

On day 1 there was more oversteer. I was running slightly higher pressure in the rear than normal. Also the entire event I ran a stiffer shock (rebound) setting than normal. In hindsight, since the course was fast, I probably should have softened the rear slightly to make it less loose.

Day 1 front/rear: 40/35psi (hot), 10/5 stiff, half tank
Day 2 front/rear: 39/33psi (hot), 10/5 stiff, full tank

I want to experiment with 1/4 tank, slightly softer rebound and lower the pressure in the rear until it isn't loose. I need another TnT.

Tires are RE71s, 275/35-18 all around.

Only vid I have is my dirty run from Sunday (59.9) in the iRacing SSR Z06. Clean 60.x was still good enough to be 4th fastest on the day. I'm too used to driving street prepared cars so my hands are way too busy for stock class cars that move around a lot more...

I run down in dothan and rarely in Pelham, but I have found that anything below 1/2 tank will get fuel starvation and will hurt you. I am running eibach bar front full stiff, koni yellows front full stiff and rear about 20%. rear camber at 2.0 and 275 rs3's all around at 37psi front and rear. I can not get the rear to rotate in the corners at low speeds in second. just thought id share and see if any of that helps. hopefully ill get up to huntsville one day and see what its like at milton frank

37 psi seems high on the rear and low-ish on the front. I guess the low in the front is OK if they're not rolling over too far.

Do you know what your rear toe is? At the TnT last week, I had 5 runs where I tried adjusting shocks as follows:
100/20% stiff, previous setting, was pushing hard.
80/20, got worse.
100/30, slightly better.
100/40, even better.
100/50, rotated the best, but in hindsight I think this was too loose. I think 40% would have been best for a high grip surface.
I definitely recommend Milton Frank in Huntsville. Great site and we usually get through things quick. Lots of fast drivers in our region.

I thought the same with the pressure up front but no rollover, i kept the rear up at 37 for less contact patch to help swing the rear around on slow corners, my toe rear is -.02 on each side. I will have to try tighten up the rear, i run mainly on concrete so it will act a little different from what you guys have but i will try it.

I think you need to take out some camber in rear. Our differential is very weak. It's a viscous diff (not mechanical). In a mechanical diff, you want more camber. But in a diff that's struggling to put down power, standing up the tire (less rear camber) will help you (per pro level autoxer). I think -1.2 to -1.4 is a good spot. Try it out.
