Well lets start by saying i have a 89 GT. 306 soon to be turbo. I live 1 mile away from drag strip and enjoy running the car every now and again. I would like to get some slicks up under her next season, but am about to do suspension and brakes. Now i am putting a Granatelli K member with tube A arms and coil overs in front. I belive im going to stick with my road race look and suspension. So i will be ordering the road race springs for front. Now to the questions. I currently am running Eibach Pro Kit springs which is 1.5 inch drop or 1.2 somethin like that. And still have stock upper and lower control arms in the rear. I have noticed they make control arms where you can raise the spring up and down. Is anyone running these with lowering springs? Now i did a search on coil overs for the rear and got mixed opinions but if i got rear coil overs i dont want nothing thats killer expensive but i dont want a peice of shiiiitttt. I dont want the rear to feel like its moving around alot and gonna fall apart when i go into a turn. Any opions here would be appreciated. Coil overs VS Springs with adjustabe height what to do???????
