I would like to get a very low stance set up for my car and BC Racing offers custom spring lengths/rates as well as different valving. I plan to drive my car mainly as a daily with a little drifting/autocross and I need some help with specing out this suspension.

As for spring stiffness I've heard the majority of guys go with 550 Front and 675 Rear. As far as spring length goes, I am not sure what size to get.

For shock lengths, and valving, can anyone point me in the right direction for a correct daily set up that is low. i.e. Frame 1.5 inches off the ground.

Thanks guys

Don't know if you already got this sorted out or not, but here's my BC setup.

front 6 inch spring, 3 inch shorter shock, 10k spring rate
rear 5 inch spring, 2 inch shorter shock, 12k spring rate.

I have room to go down front and rear, but the wheels are in the way. Just a heads up that its physically impossible to do this without solving pan clearance issues. (my car is has been modded quite heavily to solve clearance issues, but I still wear through steering racks and subframes, cant fix the road getting in the way)

Hope that helps, definitely advise a motor swap before going that low though.

Thanks for the reply Stephen.

I went to Stance Factory, and Jay ordered me BC coils with:

Front: 8k - 160 mm Length (6.3")
Rear: 12k - 120 mm Length (4.7")

Jay said it might take a while for the coils to come in so after I get the hub/knucles welded and installed, I'll update with pics.

I have some input on daily driving a setup similar to Stephen has displayed above there. Your going to have to be extremely careful, and will probably get sick of it. If you have an open dif don't try to take any steep driveways, you'll end up tri-podding going no where quick and trust me, the women will not be impressed hahaha. I speak of experience from back when I liked to rub some fender here and there
