Front Tire Size

In my opinion 6-8 lbs of air won't even be .01 improvement

I footbrake with no 2 step (currently). It doesnt mention what launch control setup... 6-8 pounds and changing RPM will affect mine enough...

2" diameter change in front tires can be .010-.015.

This depends on what the change in air pressure is, "from what, to what". 40 to 46psi? No, you're not going to see anything. 30 to 36? Yes, definite change.

I wrote an extensive (10+pg) editorial on www.thisisbracketracing.com covering bottom bulb reaction times and how to adjust them. It is a subscription site, but worth every penny and then some.

I have seen Dad as low as 18lbs on the 26"! I bought him a set of 28" old school Moroso he runs some where around 30 now.
