It is an a4, I was thinking the next mod would be lower control arms or something along those lines. I always spin coming out of the hole no matter what. Running Nitto 555r's, I lowered my pressure to ~20psi and my times actually got worse. 13.17 was running with ~30PSI in the tires.
The 555r's are an ok street tire, but if you want something to work well at the track you need some et street radials or hoosier dot drag radials at the minimum. If it were my car I wouldn't put another dollar into it without getting a good torque converter first. Check out the results of my truck, completely stock ls1 with less power and just a good 4000 stall converter and regular continental street tires. https://ls1tech.com/forums/drag-raci...s1-sonoma.html

There is nothing crazy about a good torque converter. I drive my truck everyday rain snow or shine with the 4000 converter. Best mod you can do for an auto hands down, and no matter how loose of a converter you get it will still lock up at 38mph like factory.
