Built a new dirt mod towards end of last season. Having a problem with tight entry. My driver likes a tight car for his driving style and car has great forward bite. Driver likes to pick his spot, pitch the car in,sidestep the throttle and let the engine breaking start to set car and then use throttle. The car has springs LF800 RF900 LR200 rr175. The car is a 2-link with long lift arm. Short 14" trailing arms at steep angles, with springs behind rearend. We use the axle wrap and trailing arm angles to provide the anti-squat. Brake bias has little affect. 54%left 58.5%r 54%C

Take a little cross out of the car....with your scalings...it will free it up some.

My car always loosened on entry by adding cross.

BB...there is a point that where you have too much cross and the car never will transfer enough weight to the RR to let it turn. I have experienced this in my car.....it overrides the balance.....

There is a really fine line.

You might try to loose some left side weight.We usually run about 52%.The high cross should loosen the car on entry but does sound a little high.Check the brakes I can turn mine backwards by adding rear brake or make it push with front brake.

I don't know what I was thinking when I read the cross but 54% is high. I thought 48 to 52 was about normal.

I wasn't paying enough attention when I read the cross, I thought it said 44%. I would definitely take cross out if it is at 54%. Thanks for responding to me Jammin, everyone was probably what I was talking about. I try about 49 but can loosen the car on entry going to about 51.
