Re: tire height

The difference between 24 and 26 inch front tire is more than you might think . Even tire pressure has a big effect . An example . This weekend a buddy who runs a 26" tire for the look was -.001 and .004 . I took 5 lbs ( a big move ) out od the fronts and he was .036 next pass . I went up 2 lbs and he was .024 . I run a 25 inch tire with 40-44 psi . My new S-10 will be set up with a 24 . 22" tire changes the caster to much for me . Rear tire pressure has an effect on reaction time also .

Remember when you light the pre stage you have just broke one beam . As you move into the second beam you have about 4.5 inched before you put the prestage out . If you just tickle the second beam the tire has to move more before it triggers then say taking a bigger bite at staging were you ar 2.5 from triggering .

Typically what you take out of your reaction time adds to your 60' .
