A gear swap is next, going to 3.55's. That should help out a ton. I would be running on street tires, Goodyear Eagle GS-C. What rpm should I launch at?
Just practice with you launch techniques...you want to get the most "power" to the ground with out spinning your tires...it is a fine line but once you find it...you can knock off 2.0 60 fts...
