My driveway goes up and then down. Making it look like a mountain peak. My problem is when i got springs on my 2001 mustang gt. i scrapped with long tube headers and x-pipe. Will i have the same trouble with my 2001 cobra with headers and a prochamber and exhaust????I was looking to get springs on my cobra--steeda- 1.25" drop. Would 18" wheels give me back my inch?? Thanks
