Be careful going to high on the spring rating. I put a set of 002-003 springs on my 1974 Duster that had been lightened and the car handled like crap going down the track wandering around. I took them to a local spring shop where we took them apart and dearched them some. That helped big time and I ended up going 9.80’s with them 30 years ago. With the track prep today they will and do work but if my budget allowed it I would go a different route.
