Lowering Springs & 60' Times...

[anticubicle]

So I've got a set of Steeda Sport Springs waiting to be installed on my car (no cost, was a trade). My question is, how will these springs effect my 60' times?

I've been cutting 1.7's with stock suspension, I plan on getting Control Arms (Adjustable Upper, Billett Lowers), my worry is that with the stiffer spring my 60' times will suffer.

Anyone experience the difference? Thx

I didn't notice any adverse affects when I lowered mine. These cars hook up pretty decent so if you get the adjustable control arms and set the proper pinion angle I think you'll actually gain.

Be advised that I have very little experience in this area, but I wouldn't think the springs would hurt at all. If anything, the higher spring rate may help to plant the rear wheels.

Either way, I think the 1.7 60' is nothing to sneeze at. On stock tires, that seems to be a pretty good accomplishment.

They aren't stock tires. MT ET Streets.

This is in a MM&FF article talking about the Steeda Q335. It wears the 275/40-18 Nittos and uses the Steeda sport springs along with other goodies and gets a sub 2 second 60' time. I don't think those springs are going to be harmful to your weight transfer for the strip too much.

From the article:
In order to improve the S197 platform, Steeda makes a host of modifications beneath the unibody chassis, starting with its Sport coil springs, Pro Action shocks and struts, front and rear antiroll bars, strut tower brace, and G-trac brace. The antiroll bars are fixed to the chassis via Steeda's billet brackets, and out back our Q335 had the optional billet aluminum trailing arms.



Florida's February weather saw the Q335 breathing in an easy 75 degrees of air temperature-not the great air we're used to at E-town, but better than trying to snow plow the track surface with the Steeda front splitter. BMP's staff had the racing surface nice and sticky, and our first pass of the day was a 13.24 blast at 105.09 mph, with a 1.98 60-foot time. We had, of course, powershifted each gear, and the track simply wasn't up to holding the 1-2 exchange, so subsequent runs were speed-shifted from First to Second. Pass number two was a 13.25 at 105.65, and our third effort of the day saw 13.22 at 105.16 flash on the clocks.

Well, this may be a very overly generic observation, but anytime I've seen a car at our local dragstrip with any type of road race suspension components or set up, the short times really suffer. Lowering springs and/or higher spring rates reduce weight transfer, which is critical for sticking a great launch. That's why I'm so happy with the stock GT suspension and decided long ago not to mess with lowering it or doing the Ford handling pack.

everything is a compromise. if you want the car lower, it affects drag racing. if you want a better street ride, it hurts drag times. if you want the car to handle the freeway onramps better, it hurst drag times. if you want a 100% drag car, it can be set up that way. anything for comfort on the street, and its gonna hurt you 60s, no doubt.

you are gonna have to settle somewhere in the middle.

You're answer.

I would say there is a good chance lowering springs will hurt your short time.
I decided to keep my geometry stock and my 1.6 times are on 100% stock suspension. If you get wheel hop - then upgrade control arms.
If not why bother? The stiffer poly bushing just prevent torsional flex.

Thanks for the replies. Going to do some thinking about it.
