I am heading back to the track next week with my 06 gt the mods are udp's, slp axle backs, lower control arms, bama 93 race tune and ford racing cai. I had the car down the track last season same mods except the ford racing cai. It ran a 13.51 with the stock paraelli street tires 2.0 60ft and tire spin in 2nd. I am going back to the track with 315 nitto drag radials on a 17in rim and the added cai. How much better do you think i can get out of it with these mods? I feel like I lost a good amount of time in 2nd gear bc I had some nasty wheel spin but hopefully these radials will help. Give me some est et's car is a 5Speed manual
