In my case, cost for lowering the car was bout $750. Breakdown is approx $300 for springs (F&R), $200 for camber kit (L&R) and $250 for fitting including wheel alignment. You could do it alot cheaper. I have seen the springs for as cheap as $230, some would argue that you dont need a camber kit, and you could install the springs yourself, so if you really wanted to you could do it for less than $300. I was happy to pay a bit more for the luxury of being able to just drop the car off and have it done properly. Handling wise the car is much the same. The ride is definately firmer, and combined with the larger wheels you feel every bump in the road. This doesnt bother me, but some people wouldnt like the change in ride comfort. Couldnt really comment on the pros and cons of drag racing with these springs but if I had to guess I'd say its probably not the best option. Russ, fairly sure you can have these springs compressed. Not sure on cost.
