If you must use the factory stock suspension components;
Ditch the 90/10 's. If it still has a front anti-sway bar remove it. If you need front lift, remove control arms and measure length of bushing with teeth. Grind teeth off of bushings. Hone inside of bushings so the bolt is a light slip fit. Lube it all and install control arms with modified bushings using shims or washers as shims to take up the space the teeth you removed occupied. A good Variable Rate front coil as made by MOOG etc for the SB car should also help.
For shocks a good adjustable front from Strange is great but you can also do it poor boy style by either buying the lightest duty cheap shock you can find or by going to junk yard and trying the shocks by hand until you find two with similar feel that is not worn out but is not super stiff either.
All of that extra work will give you much quicker front suspension rise if you need it than the 90/10 gave and you can better control the car when it comes down and it will not unlad the rear tires plus it will handle much better all the way down the track.
