coilovers would be a good investment....this way for the dragstrip you could raise the rear end of the car so that on launch the front wont raise so high. the front raising so high will lose traction since that makes the rear sag. make sense???? good...because it has never made a diffrence in my 60 foot times when i do it. lol so basically since you are going turbo...i would suggest you figure out how to have turbo lag help you with traction problems. sway bars help a lot too....they help to equal the force between side to side and you can kind of think of those as springs.
