I have the SLP Loudmouth 2 catback on my 88 GTA and my springs are bad. So I'm looking to get some Belltech 1 inch lowering springs, since I dont know much about springs, do you think 1 inch drop causes a problem with ground clearance? Do these lowering springs handle stiffer (shorter way of bouncing distance, idk how to describe this lol) I'll get the height numbers soon.
Yes, I think a 1 inch drop will cause clearance issues. I have borla catback with a custom pipe mated to Doug's headers, and Eibach springs with koni yellow shocks. Going over train tracks in non-rural areas (so they are paved pretty smoothly) makes me nervous because of the rubbing. If I could do it over again i would save myself an inch.
Back when these cars were new a person could buy one with a bevy of options allowing the car to be pretty light with a manual transmission, as few electronics as possible, a hard top and lots of deleted items/options. Conversely they could really load up an IROC or GTA and make it 500 pounds heavier. The lowering spring companies, only caring about profits, have no intention of offering half a dozen different lowering springs to ensure that the drop is indeed only 1". The aftermarket companies sell one lowering spring for our cars. So naturally member's reports of adding aftermarket lowering springs are all over the place. Some have said it raised ride height, some it stayed the same and others have lowered it anywhere from 1/2"-2". So everybody says "Do the research" and look up threads where similar spec'd cars have used the springs and see their results. When I was looking at springs I did just that. I searched and searched and still found contradictory stories. My research concluded that the best way to go about lowering a thirdgen was to buy stock replacement springs and cut 1/2 a coil at a time till you get the drop you want. If that sounds like too much work than a weightjack is what you want. I used the cut coil method on my last car and it worked, I put them on my current project and they don't sit right so I bought weight jacks.
If you have the stock exhaust you can do a better job of getting the exhaust tucked up under the car more. My car is lowered and I have long tube headers with 3" primaries going to a 4" single and the only place I have a problem with my exhaust is the UMI tranny cross member
