? about drop springs at the dragstrip

[1 BAD RS 2 SS]

i've been running drop spring on my car sense 2009 when i got the car . i started modding in the winter of 09 & i've been pushing 650+ rwhp with a D1 procharger through a stalled auto ever sense . i've ran a best of 10.78 et @ 127 mph with a 1.58 60' . i've never ran my car with the stock springs , so my question is . are the drop springs holding me back compaired to the stock springs . thanks for any info you can provide

[SUKXOST]

guessing no. different spring rate aside...shorter spring = less "squat".

You're obviously hooking up pretty well with your setup.

We have many members running real fast times with drop springs. But I can pretty much gaurantee these same cars would run faster without them. Drop springs are not the best setup for drag racing.

My guess is your 60' times would drop down in the 1.4x range with a more specific drag setup. GM High Tech even did a drag test swapping out a set of lowering springs with drag specific springs (springs made for drag racing) and the car's 60' times dropped nicely (down into the 1.4x sec range).

I think drop springs will always be better than stock, but there are better set ups.

i would say that if you have stock suspension, that would be more of a set back than the springs. The newer camaros have the advantage of better durometer rubber bushings. nothing that BMR or any of the other suspension companies couldn't help you out with

thanks guys . heres somemore info

i've got bmr lowers , adj. toelinks & trailing arms along with the jre posi mod and 17" mickey dr . i'm thinking that i maybe loosing some of the weight transfer due to the shorter springs . what do you guys think or am i just over thinking ? i think the car has more in it then a 10.78 with the current setup .

Lowering springs are not ideal for drag racing but neither are the stock springs. There is definitely no reason to swap back to stock. If you want the optimal set up you should be looking at a set of drag race coil overs. That alone should knock a solid tenth of your 60ft.

thats probably as good a setup as you can run. i would add diff and cradle bushings but thats a good 60' time already. probably get it down to a 1.50

The lowering springs can kind of be a double edged sword. The springs lower the car which makes it a little harder to transfer weight in the front but they have a bit stiffer spring rate which helps keep pressure on the rear tires. With the power your car makes it shouldn't have any problems transferring weight which is pretty clear from the 1.58 60ft times you have. It really sounds like you are doing a good job of maximizing your setup.

I agree 100%. Adding these two parts would definitley help out with the 60ft times and make the car more consistent.

You have a good working set up, beside the suspension upgrade mention above. Gears and or loosening your convertor might help your ProCharger get into the power band a little quicker. Good luck and Keep us posted.

my mind of thinking would be , shorter spring less movement , so the car would be stiffer and cause it to spin a bit more easier , softer taller springs would be almost the same effect as a 20" tire vs a 17" . i could be wrong tho .
but u drive the hell out of that car ,
just thought of something tho , the last 1/8 u probably gain a very lil vs stock cause of the uplift and being lower to the ground so not having as much air to cut thru. but they would be very minimal .

chase what drag shocks ( full set front & rear ) would you suggest for my 4000 lb pig ?

thanks guys for all your thoughts .

i'm looking to maximize my current set up for now . then a forged bottom end after that .

If your going to do anything, drag coilovers would be your best gain. Don't even bother with stock springs, your better off with the drops in the rear and stock in the front though. The stockers would help weight transfer and lift to the rear, and the drop springs in the rear would help keep it planted. The rear of this car squats to much with stock suspension without enough front end lift.

Try disconnecting or removing the front sway bar and set the rear sway bar at it stiffest setting.
