I went with the BMR minimum drop springs. I'm running 19" 35 aspect ratio tires front and rear and for me, the amount of drop is perfect.

I did Steeda Minimum drop. Was perfect on my 18 with the Whipple.

You guys with the drag springs, how does it handle compared to stock? I want a good launch from a dig but I don't want it to handle like a pig.

I am running the BMR drag springs and have no issues at all...

I went with the Steeda Progressive; running 275/35R20 and 305/35R20 with no issues.

Personally I'd stay away from progressive springs. They rarely perform in concert with your shocks and struts. After my whipple I ditched my Ford performance progressive lowering springs and went with BMR sp083 springs and FPP track pack shocks and struts. Car handles like a true sports car and I cut 1.5 60ft at the track on 11lbs/e85

What is the logic behind your statement? No track duty here.

Not sure what you are asking? Progressive springs are soft up top and the changing rate rarely matches up with the what the shock or strut is doing since it is not consistent. Progressive is a better spring if you want a more comfortable ride. But for track or even aggressive back road driving, linear springs are more consistent and therefore more predictable. For digs or drags as one person commented, progressive springs are too soft up top and cause the car to squat too much, hurting launches.

That is a better explanation. As you stated for normal street driving they are fine. I agree you want linear for dig or drags.....though I think many, make that most, people who own these cars don't actually race them :)

I had the sp083 springs on my last car and loved them but it was N/A. I wasn't sure if it was too stiff a spring for the front since I am looking for strait line traction a bit more now that I am boosted. All the the "drag" spring combos have much softer front springs so I just assumed.
