thinking of lowering mine

[timeoutdan]

What do you guys suggest. Don't want to sacrifice factory tuned suspension for looks.

[jerseytaylor]

dont

I wouldn't recommend it. The car is already factory lowered for performance and most likely anything you may do would negatively affect that. Plus, I imagine your ride quality on the street would probably get even worse not to mention that you would raise the risk of damage to the front splitter and other items under the car from road and driveway entrance hazards.

Those two dont go together. Lowering a car, modifies geometry. If you're worried about sacrificing factory suspension geometry, dont lower the car.

I wouldn't mess with Z28 suspension unless you're going for some high end coilovers

That settles it I'm not lowering it. Thanks guys

So no one has lowered theirs for track set up?

I feel the car is to high. I would like to see it sit a half inch to an inch lower. It will lower the center of gravity. I dont care if it rides harder. It rides fine. Rides better then several of my other cars. I think it needs to be a little stiff on the track. My Z28 is much higher then cup cars and clearly softer.

I've been running the DSE speed 1 kit for about 4 or 5 months now. The kit comes with springs and matching sway bars. The rate on the springs are a pinch softer from stock from what I understand, but the sway bars are noticeably larger/stiffer. I also installed delrin sway bar bushings and moreno camber plates.

I track the car regularly and have been very happy with how the car has performed (both stock and modified). The additional camber gained from the camber plates is probably the largest source of "improvement," at least in terms of turn-in/steering feel.

Overall very happy with how the car rides and performs. Next up will be a set of lighter fixed back seats so I can store the stock ones.



Loving the heck out of this thing!

How much did the kit lower the car?

Looks like from the kit information 1.5" front and rear. But kit is for Gen 5 Camaro, not Z/28 specific, so while springs are stiffer than most Camaro, they are softer than Z.

Here is you tube video from DSE on Gen 5 cars:

I believe its a 1.5" drop for SS - the Z/28 is already a little lower than the SS from the factory, so I'd say this was about an 1" lower than stock Z/28

Good point - 33 mm/1.3 inch lower center of gravity than SS and Z/28 springs are stiffer than these as well - as GM stated they were 85% stiffer in front and 65% stiffer in rear in marketing materials.

See attached from GM information package when Z was introduced.

bump for further information?

I'd be interested in lowering 10-15mm or so.. Wondering if having a custom spring made, matched to the OEM one in rate but just slightly shorter would be best option. I know there are companies that can do custom wound springs. Allows you to keep the DSSV Multimatic dampers too..

The DSE Speed 1 Kit is pretty close to the same spring rate, but are lower by about an inch, and have a much larger matching sway bar. I've had them on the car along with a caster kit and the moreno camber plates and have been very happy with the results.

The ride is actually a little more compliant than stock, but there is actually less body roll, probably due to the larger sway bars. No hopping around or anything.

In the future I think I would consider upgrading the entire system for either a Penske or Moton coilover, but until then I'm extremely satisfied with the DSE springs on the DSSV dampers
