Wait, so are they the M/T ET Streets? Or the M/T ET Radials? if they are the et streets then 30 psi is WAYY to much for those tires, they like around 15-17 psi and a nice smokey burnout. Never raced on the et radials, but I will soon.

ok, it they have the curved grooves in them, then they are the radials, if they have just 3 straight lines going through the middle/outside of the tire, they are the et streets..

Try about 17psi, and a short 5-8 second burnout. you shouldn't have any problems with traction with your mods. i have et street RADIALS, and have no problem cutting 1.6x times all day with a best of 1.61 -Jim

just be careful, the lower the psi, the more the rear end gets squirly when you let off the gas. The rear ends tends to sway when you let the weight off the back tires because of the low air in the tires, it will suprise, but DO NOT try to correct, it won't be pretty..
