fordracing65,

I was surprised to see this up again but assume it is recent.
Front tires: trying, 315x30x18 and 275x35x18 still have not made a decision on brand or size. We run both front and rear bars and both are set full soft
front bar is 1.25 D with .125 wall and blade adjustment, rear is .562 D the car is so low now that to run 315, ride height or camber has to be compromised to avoid body contact. Rear can run either 315 or 335 but we have not evaluated 335 yet. Small tight tracks that have low grip seem to like the narrower tires because they get to temperature quicker. We are running more tests this weekend at a location that is lower grip than airports but better than Goodguys surface. I have installed an idler pulley on the alternator belt to try and keep it in place at 8000. I also changed some seals on the front wheel bearings and installed a 10 psi check valve to try and cure knockback.
If I can solve those two problems we can get on to fine tuning the chassis.
