Will 1" drop springs hurt my drag times?

Will 1" Hotchkis drop springs hurt my launch of the car? I am hearing conflicting info on this. Will I lose ET or 60 ft? Anyone with personal experience drag racing a 5th gen with 1" drop springs care to enlighten me? Thanks!

That's what I am believing also. Just trying to get as much feed back on this matter from real world experience. I have a reputable source telling me otherwise.

It's supposed to help. I watched a youtube video showing before and after on a Camaro a while back.

Yea, I cannot imagine why it would hurt... now if you get into the 1.5-2 inch drop range, I could see it maybe hindering you. However, most C5-vendors I have spoke with stated 1 to 1.25 is an optimal range in almost every application.

Yes, they will. Period. Lower is not faster on the dragstrip in this case, it's just going to hurt your weight transfer, increase your proneness to wheel-hop, and lessen your traction.

So, coilovers with adjustable dampeners are probably more beneficial at the strip? Thanks for all the replies.

If you want to get serious about drag racing look into PFADT's drag racing coilovers!

If I have pfadt springs/sways lower me an inch...and a complete bushing kit... which are told to minimize wheel hop and have... how then would I hit the strip and all the sudden get it back? No disrespect intended, I am just curious... mine is a DD, but I would like to hit the strip once or twice a year...

TornadoSS – We’ve been running our F-11 project Camaro at the strip with some great times and traction with our Race Pack suspension package, which include our drop springs and Chassis Max Brace. You already have the brace, so that should help with 60’ times. Before purchasing drag specific parts, consider what percentage of the time you drive your car at the drag strip and how you want your car to handle on the street.

The car is mostly street, with occasional strip use. Is the F-11 car a manual tranny car? What kind of times are you getting? Thanks for the help!

I still say they will help, youtube it, I watched a camaro become quicker with lowering springs.

I put Hotchkis spings on my car when it had about 1,400 miles and never got a chance to get to the drag strip with just the OEM springs so I can't give you a real before/after experience with them at the track.

What I can say is that I've been able to turn what I think are some decent 60' times with stock tires and with the Hotchkis springs. The time I turned these numbers my only suspension mods were the Hotchkis springs and Spohn trailing arms. With the stock tires at 25 psi I turned a couple back to back 1.98 60' times. However, I will say that typically I'm in the 2.0 range.... like 2.02 - 2.05. That's with an M6 car.

I really don't think the Hotchkis springs are going to hender you at the track. There will be plenty more variables that will cause you to go slower like bad weather or a not so good launch.

From a looks stand point....drop your car. They look much better lowered.

I think ultimately a set of coilovers is going to be better than just drop springs (which is one of the reasons why I'll have coilovers on my car soon) because you'll have the ability to make adjustments to firmness/softness to help with the launch. However, there is a big price difference and install factors between a set of spings vs coilovers.

Lowering springs lower your instant center, which will always lower traction .
Wheel hop is produced by a lack of traction.

If you arent cutting at least a 1.5x 60 foot time, your comments on lowering springs increasing traction are irrelevant, as you arent remotely close to pushing the chassis.

I've been going back and forth on this for over 2 years. My conclusion was that it would hinder the weight transfer. Making for less room for the car to squat. I have no idea if I'm right or wrong but my car, with the wheels spinning inside the tire, has been pulling off 1.46 60's for almost a year and a half on the stock suspension.

Generally (specifically on solid axle cars) lowering will hurt weight transfer because it alters the virtual lift point location of the suspension (instantaneous center). Even in these cases, this is fixable by re-locating certain suspension components to compensate. This problem is not near as relevant on independent suspension cars, at least up to a point. We have been running our Project 2010 Camaro at the drag strip for 2 years now. It has been at various heights along the way but we have maintained low 1.50 sixty ft/times regardless of ride height. This is on an 18" Drag Radial and we have been consistently within .05 seconds on 4 different tracks, 8 different runs, both lowered and at stock height.

Basically as long as you lower the car a conservative amount (1 inch is fine) and retain enough suspension travel to keep the car off the bump stops when you leave the line, you should be fine. Whether you are drag racing or auto-crossing, it's never a good thing to hit the bumpstops...

We will echo the comments made earlier in the thread. Lowering the car isn't optimal for those looking to drop that last Thousandth off their 60" times, but until you start seriously preparing your Camaro with Drag radials and making really big power it's not enough of an issue to warrant not upgrading the suspension for looks and handling improvements.

Ideally you want a long, soft spring with a tall ride height in the front of the car to rise, and a slightly stiffer and higher damping rate in the rear to keep the rear end planted. Drop springs typically increase the spring rates over stock as well as lower the ride height both front and rear. Theoretically in a perfect world they may raise 60" times, but in practical application most folks who aren't fully track prepared won't notice much change after drop springs.
