I have a 4.56 gear to put in the Mach. At the track I have always run drag radials and was wondering if you think a drag radial will still work with a 360 hp (at the wheels) 5 speed. Suspension is done, welded full lenght sub frame connectors.

I see lots DR working with automatics but no so many 5 speeds. My car does not have crazy power but I also do not want to buy DR for the track and blow them off or be inconsistant.
I also want to launch in 1st and am hoping to still run a 26 inch tall tire, Red line on the car is 6800. Rim size out back is 15 x 8 1/2
Is is time to go with a slick or Et street or get the Mt's or Hoosier on again? Why I am hesitant to go to a slick is I have always had my car on a drag radial and it is as fast on the street as it on the track or close anyway!

What do you all think?
Appreciate any advice!
 
There have been cars running into the 7's in the 1/4 mile with MT et street radials! The 275/60/15 is a very good hooking tire. However, it is 28" tall. They also offer a 275/50/15 that is 26" tall, but I haven't heard much about them. The added sidewall of the 28's should help with your launch. I run the 255/60/15 (27" tall) and have ran a best of 11.90 with a 1.71 60' time. I am making roughly 375 rwhp and 460 rwtq on my 125hp shot. Also, I have 5 speed with 4.10's.

Thanks for the info on this, appreciated.
