Drag Racing Tech - Trans Am rear spring weight

I have a 2001 Trans Am ws6 with a mild ls1. Cam, long tubes, bigger injectors, and the ls6 intake. Its lowered and when i took it to the strip all she would do is spin. i could not get it to hook up. I know it being lowered isnt helping it so i want to know what pound rear springs would work best for my car. btw it was on street tires also.

Get some LCAs and a relocation bracket.

it spun on slicks or drag radials? if you're running street tires you're just wasting your time

street tires. but i know i need better rear springs even with the street tires on. i hear v6 springs work good
