One thing I'd like to add here, tires are nice, but a decent set of lower control arms will make a huge difference in how the tire bites. Tonight I put on a set of Steeda's aluminum lower control arms I got in trade for doing some work. Took the car out for a test spin and the dang tires were digging hard in first where before they would spin pretty easily. The car was bucking and digging in first like it had a set of slicks bolted on. Also subframe connectors make a huge difference in how the suspension works and how a tire acts and feels on the road.
Guess it says a lot for a $100 tire to hold back 390 RWHP with 3.55 gears, but these fuldas were doing the job.
