No Oshberg for me either.
I think you got it reversed, always thought that toe out caused it to wander, and toe in more stable, we were always taught to have just a smidge of toe in. Also the toe out gives the inside wheel more turn in right?

I had quite a bit of toe in on my car sunday and it was very unsettled. An absolute chore to drive. Advice from Stan, put about 1 degree toe out. Kept the ride height at 5mm and .5mm droop front and rear. And the car was extremely stable.. Much easier to drive. Then Tim helped me with the dual rate and now it's game on!!!

I'm just regurgitating everything I've picked up looking at the best 12th scale racers setups. Most run their front dead straight to .5* toe out. I have no issue with the car wandering under power running that way. I have more issues if my diff is too tight.

More Ackermann, the more parallel to each other the front wheels are at full steering throw, the more aggressive the car will turn. Also with the links angled the way they are out of the box, the car bump steers to toe in, which makes the car really aggressive. If you reduce Ackermann, the load bearing outside tire will be angled less and softens the mid corner grab. Perfect Ackermann would be inside and outside tires turn in perfect circles without tire scrub. I've never had it perfect, but it's a good thing to adjust if cornering is too aggressive.

Thanks Stan, toe in is exactly what I want, I need it to dive in less, and turn more out of the corner. The best I can figure this was the only difference between my car and my dads.

Emberassed to say what the issue was. The screw on the left front castor shims was loose allowing the whole left front to flop around. Going out on a limb here that was causing some handling issues. The toe in will help too.

Incredible day of racing. 15 cars. Gotta love it. Everyone's car looked really good on track. With any luck, next week will continue the trend.

A second or two in quals can drop you down two or three positions.

Some surprising results.

Car stability is a big one for me, have some tricks up my sleeve for next week to hopefully keep the car the same as the traction comes up, varying the traction compound is not the best plan

Stan gave me some ideas to work with so look out next week

So curious to the whole racing etiquette deal. At 4:40 in I let Matt clear the right instead of forcing it and then I got inside of him turning into the turn before the loop and held my line to not get pinched turning into the loop straight and we got together, both still going at the end of it. Who is that on me, Matt, or racing for same spot?

So sorry to Matt if that was on me.

I'm curious what others think too. I'd chalk it up to "just one of those racin' deals" Also, the carpet on that particular turn makes the car do weird stuff even if there isn't another car there.
