______ARK Performance DT-P/ST-P Coilover_______

ARK Performance Fully Adjustable Coilover Kits provide the ultimate in suspension technology for your street or track car. 16 levels of dampening adjustment allow you to fine tune the ride to your handling and comfort needs. The dampening adjusts compression and rebound simultaneously for ease of adjustment. Pillow ball top mounts in the front and rear on some applications allow you to maintain vehicle manufacturer suspension geometry design. The pillow ball top mounts also allow you a more direct feel for solid driver response. Most applications utilize an adjustable lower mount, which means you adjust height without losing suspension travel like some other coilover designs do. With the mounts and most pieces of the coilover being designed for AL6061 billet aluminum the kit is lightweight, durable, and rust resistant. The steel shock body is electroplated with zinc to resist rust and the elements. The valving of each set is matched to the springs installed for unmatched ride quality and reliability.
The ARK system uses a Monotube design in which the oil and gas are separated within the cylinder. When compared to twin tube designs the Monotube dissipates heat better, allows finer dampening adjustments, and requires more expensive design process. Aeration and cavatation are a lot less common in a Monotube design, which results in a better ride. The ARK DT-P Coilover system has been designed with professional road racing in mind offering extremely high value and performance.

I think you'll find few responses because most of these coilovers have similar construction, but slightly different spring rates and valving characteristics. There are a few things about it that instantly say not geared for track driving. The spring rates should at least be equal or higher in the back. There are 2 other major concerns that I would have, but I kind of already know the answer, so they're loaded questions.
How much droop do you have? (very, very little, which means a brutal ride over bumps)
What does the force-velocity shock dyno look like? (straight lines or progressive, unless turned all the way up. Might go slightly digressive at max. Again, brutal ride over big bumps if you tune it to proper damping at low speed)
If you really want to set yourself apart, improving the valving and spring rates, and publish the (industry standard) dyno chart. It will do wonders for you.
Honestly, I would love to be wrong.

Appologies for the late response. It seems as though we should have subscribed to this thread.
Our Dt-P and St-P coilovers have a 16 level height adjustment, So drop rate is nearly unlimited.
From fully slammed to monster truck height. LOL . Appologies I have never seen a race track with speed bumps..
Also the difference in spring rates from front to rear is all personal prefernce. Our Street spec and Track spec are dyno proven and track tested.
I may have some shock dyno's, I will be sure to post them up once I have looked through my files.
Let me know if you have any more questions Wang.
Thanks.

The shock dyno for this application will tell the tale. If you would post them, that would be great. Thanks.

Agreed.
First thing people picture in there head when they hear race track is FAST!!!
Track driving consists of alternating from high to low speeds constantly. Especially when cornering, which is why a good compression and rebound setting is very important. Thanks

We have done shock dynos for the 350z application to do some fine tuning with its application. We have close ties in with an independent shock company that does all the dynos for us.
Please use this as reference for now, and we will provide you the actual dyno for the cobalt Models as times progress






Our ARK Performance z33/350z coilover set up are somewhat comparible to the cobalts.
Spring rates of z33/350z Dt-P Track version is F 12 kg/mm R 11KG/MM

I think it's admirable that you guys are open to posting information about your products. However, those graphs confirm what I was saying earlier. Looks pretty much linear for rebound and kind of digressive for compression. Unfortunately, most shocks of this construction have very similar dyno curves. Like I mentioned before, the spring rates also need to be higher in the rear for a high performance application.
Thanks for posting the info. It's much appreciated. Would be better if it was for the Cobalt app, but this gives us an idea what to expect.
