Going with a car from track with a .370 Pro Tree we are double O's on, to a track with a .400 Pro Tree. Both tracks are Compulink.

How much will 9" of additional rollout on the front tires pad reaction time ballpark figure? We can't adjust the chip lower because it's a radial tire car we're gonna race at Lights Out SGMP in the new DXP class. The car has a fast Pro Tree transmission brake in which I could replace with a slow bracket brake I have, however I'd prefer the potential for positive ET gain of the additional rollout going from a 26" 82 rollout to 29 91 rollout with other sizes/options in between. I'm also curious a ballpark figure how much in positive ET gain there is potentially with the additional 9" of rollout 5.0's 136 mph 1/8 mile staged shallow.

I figured nobody could answer these types of questions better, more accurately than Stock and Super Stock racers. Thank you ahead of time for any input. We gotta get some front runners to accomplish this, not exactly sure which to go with.
