Default STS Questions....

Im gettin ready to order my sts kit but i have a couple simple questions...

1. I have sportline springs on my car now, and i know thats WAY to low BUT what springs are good enough? Or am i just goin to have to put the stock ones back on?

2. DO you HAVE to have a aftermarket fuelpump or is the stocker good enough for about 475hp?

For 475RWHP, yes you need an aftermarket pump & bigger injectors. I run an Aeromotive 255gph in-tank pump + 42lb injectors.

Lowering prings are NOT your friend. See pics of my STS with STOCK springs.



If you have any Q's on the install, feel free to PM me.

i have the walboro 255 in-tank and i have SVO 42's in there. i made 472/501 on 7.5 psi. i dont think lowering an STS car is good but i will eventually do it myself. but of course i also want to go front mount too.

i believe that my AFR was 11.9 if im not mistaken.... i could be wrong.... it went 472/501 with 12.0..... then the FAST 78mm that was on it started to crack due to the way i installed it and the Granatelli MAF was throwing the tune off. so now its all stock
