Hey all, am looking to lower my 15 gt pp. I have 1" wheel spacers on all four corners. I want to lower but i guess no more than a 1" drop. What springs would you recommend. Thanks!
If you want to use the stock PP dampers, the best choice for min lowering is BMR SP089/82. Good upgrade over PP for the street handling and comfort.
If you plan on upgrading dampers, you can use the the GT350 track pack or R springs, or a combination of GT350 front and BMR rear. These are a good compromise of street and track capabilities.
Now, if you have really stiff dampers, there's the upcoming Steeda dual rate springs that drop 3/4". These are definitely more track oriented.
There are not a lot of choices for less than 1" drop.
In order of what my personal preference would be taking into account spring rates, the fact you're using PP dampers, and drop aesthetics... for a daily driven car:
Steeda Progressive - excellent ride quality, nice drop, excellent mountain road handling
Swift Spec R - stiffer, linear spring, light, predictable, front rate helps steering response, a spring that works on track as well as street
BMR SP080 - more conservative drop, close to stock spring rates for ride quality, something I'd use for a strictly street driven car with 20" staggered wheel setup
