Where are you getting the 3k price from? buying every think i sell, tune, exhaust, cold air kit, and upper pulley all comes up to less than $1720. With the pulley your times will drop down more than that for sure. A tune alone and the cold air kit has been shown to knock you down to the 12.0 range. That only costs 320+250=$570. The exhaust adds 18Rwhp to the mix and chops off a .1 second. But makes the car sound more aggressive and frees up the torque.
I know I run my car at the track with the traction control on and it's like if It does not work, it peels all first and trips on second as well, my worst 60 ft was 2.3, I get 1.7 on my srt8 jeep, i am looking at a set of tires but so far on our size the best one I found were the F1 at 60 tread wear, but they are about $500 a piece, I used to run hossiers and bf gr drag radials on my grandnational with 0 tread wear, but they don't make our size, our michellin are 220 tread wear, the gtr brings 140 tread wear, I will keep on searching..Traction is the key word here.
