Off beat repy but was wondering about your exhaust sound do you like it is it quiet
I agree 100%...I think you should get something that you can change both your damping and also your height. H & R and KW Sports both make these "full" suspension kits but if you want to go the cheaper route get adjustable Koni or Spax adjustable struts and shocks. The only thing about the Koni or Spax is that you'll have to pick out the springs (though OEM ones should work okay)...most people who get coilovers get them so that they can ride lower around town and when they show, they cam slam the car down. people who get them for performance applications would be people who rallycross. drop it down on flat paved roads or rasie it up on bumpy dirt roads.
for your situation, if you are going drag and dont care as much about getting the slamed look, just get some regular springs with a high spring rate and some koni adjustables. you want a stiff suspension for going straight so that you keep the wheels on the ground for the best possible traction.
