for a 91' notch. just looking for input on which spring height/spring rate are best for drag. hopefully someone has more input than "stock springs"

List more info on your combo....

What Uppers & Lowers?

Anti Roll bar?

Current 60' times?

Pinion Angle?

FYI....I run stock GT rear springs to 1.55 short times.

stock sway bar, panhard,adj uppers & lowers urathane on both ends, -2* pinion angle, strange 10 way shocks. just looking for more or less the ideal height and rate/ input on variable rate springs

There are several companies who make "drag" springs you could try.

What tires are you using at the track and what does the car 60'?

On a fox, a stock spring cut down to the ride height you want it probably fine for what your doing. The shock is much more important to control the spring.

I use cut 4 cylinder springs which works for me, also rear 4 cylinder springs are the same springs that come in a 93 Cobra

thank you guys for you input. i also dont want the car to handle like crap, are the cut springs pretty bouncy?

One coil cut on a stock set....you probably won't notice.

my favorite setup is this for a mild street car (under 400)

HPM mega bite jr LCA, any or stock UCA

stock spring ok, but put a bag in it, and try about 8 lbs in it (go up to 11 if you need to and see improvements)

riding on a mickey thompson et street (radial or bias ply your choice)

this is the best setup i have seen for even double the cost

a 12 second car should hit 1.6x sixties only launching about 3500
