Right now I am running 3 wheel brakes and I realize that going back to fourwheel will more than likely solve my problems, but I don't want to add back all that unsprung weight caliper, pads, rotor and I don't need four wheel brakes for tacky tracks. So don't try to talk me out of it lol. Now I have read that traditionally you need more cross to tighten you on entry but I have read elsewhere with a higher rear brake bias such as in my case you need to lower cross to make it pivot on the lr. Right now I go into the corner to set it and then have to wait to catch back up around much later than would be ideal. Exit was a little loose but will change if I get entry better. Right now if memory severes I have around 50 cross 54 rear 53 left. After the race I checked with my hand that the RR was warmer than the LR but not by a ton. Or am I looking in the wrong place. Should I be tinkering with lead placement??

Sounds to me like you have a side bite issue. Id adjust rear roll center up a little or slow down a little sooner and pick up the throttle a little earlier??? Just fishing to see what you've tried to stop the way its acting. possibly the right rear has too much travel and is binding you up causing the car to skate. Real hard to tell without seeing exactly what your car is doing. When you know someone is using brake inputs on entry the exact entry angle at point of braking is critical. If you are braking and backing the thing in the corner then its definately a side bite issue. It is really difficult managing entry with that big rear bias. You almost have to get the car so side bite tight that the thing is going to be a bear on the tacky tracks and driver unforgiving on the slick stuff. Hope that helps?

I have had this setup working well before as have others. I just need some direction with my new car. I am planning on adjusting cross but have read contradictory statements. I am only on the brakes enough to set it. 1/2 sec maybe just a guess

To answer my own question for future people searching. Do NOT add cross it will make entry worse, found out the hard way lol

Adding cross will loosen entry and tighten exit.

The best thing I found for getting more sidebite last year was running less left side weight. I ended up down around 51. I never really worried too much about crossweight. The rear split is much more important.
Protest huh? I see how you are. Haha.

Yup it felt like a$$ for the heat race so I moved the lr out 2" and put 1/2 spacer on the rf and moved two 20 lbs weight up about trunk lid high and it worked pretty decent for the heat. If I could stay away from the crashes and get the thing running right again. I tell ya winning is bad luck. Did you see me get screwed in the C. Russ even admitted it after he saw the tape.
