DMS springs
Re: DMS springs This is the "Handling" section not the "Appearance" section. So, forgive me if I misunderstand you needs.
For handling, progressive rates on the front are not a good choice.
When you increase front spring rate, you create more and more oversteer. So, as you brake harder, the rear will be come more tail happy.
A progressive rate on the front, will increase the effective spring rate the harder you brake (weight transfer to the front). So the car will go from an understeer to and oversteer while you are on the brakes.
That is not good. And I never see anywhere on teh DMS site where they advertise the rates. That's an important fact. A Trans AM out weighs a Camaro by several hundred pounds.
If it's appearance (the ride height) you are after, these might be just the thing for you.
Eibach springs are a linear rate on the front. But they are an AX spring. They are very soft (400lbs) and require a HUGE front sway bar to compensate for their rate.
Remember ... springs support the car's weight ... sways control the weight distibution.
The best spring I've ever run is the G2 Super Spring which are no longer available. The fronts are 550 linear and the rears are 180-260 exponentially progressive, which means they stay relatively linear and ramp up progressive very quickly. These springs are like heirlooms. People bought'em and will not let go of them, only passing them on to friends and relatives.

Verdad Gallardo Re: DMS springs The AX gang uses the Suspension Techniques 35mm bar.
I tried it on a road course with my G2 springs and it pushed really bad. So, heavy springs and a heavy bar were not a good choice.
98_1LE runs Pros with the 35 bar and really likes it ...
And I guess I'm looking at this from a road racer POV. The AXers probably say:
G2 springs are a linear rate on the front. But they are a RR spring. They are stiff (550lbs) and require a SMALLER front sway bar to compensate for their rate.
It's all in one's perspective, I guess ...

Re: DMS springs I'm running 640 in lb straight rate on the front and 258 rear (per the spring rate calculation formula, a micrometer and a machinists ruler...so plus or minus a few lbs). But, I am running stock bars for now....I may try 1LE bars soon.
Re: DMS springs Out of coincidence (I do set them seperately), 7 clicks of compression on both ends (I may take the rear up to 8) with 6 sweeps of rebound on the front and 1/3rd "turn" of rebound in the rear (the rear rebound varies...I am still trying new things on that one).
Re: DMS springs Thanks, Mitch. I'm more intersted in RR vs. AX. I installed the Eibachs on the car a while back with daily driver in mind. Since then my priorities have changed and I'll probably go for LG coilovers in the future. For now, though, Louis sent me some Hypercoils for the rear since my pros were bottoming a lot. I still have the Eibachs up front, but with a solid 32mm bar (21mm rear). Maybe in the interim I'll go to the 35 ST bar up front...
Re: DMS springs DMS spring rates are:
Front: 325-630
Rear: 95-160
I am going with progressive rate springs so that the every day ride is not so bad, but when you are compressing the spring (i.e. under hard braking) I can have the heavier spring rate. Compensating for progressive springs while racing isn't that big of a deal as long as you know you have them.
Progressive rate springs on the rear will also allow you to hook up a bit better at the drag strip, and I find myself there every once in a while...
