I have been doing a ton of research and was just about to pull the trigger on the dnd shocks with the ground control and found out www.ksportusa.com just came out with a true coil over today. One member here is already running them. He has a silver car with black Atstra I-forged wheels and his car was at SEMA. I am waiting for this company to open so I can call them and find out the real info. When I talked to a rep last week, he was saying $1300-$1500, which would be cheaper than the GC/DND set up. Check out the site and post up what you think. He sent a picture of the CTS-V coil overs themselves but I dont know how to post pics.

looks nice..I'm sure you'll find more info out when you call them...but what about spring rate options and such..I'd love to lower my car, but will never sacrifice ride quality...I did it once to my camaro and I have to live with it to get the good looks...but I wont make the same mistake twice.....looks like a clean kit though.

Look on their site. It talks about keeping max travel when at the lowest setting. They open at 10:00 a.m. I will post up after I have talked to them. It has something to do with being able to adjust the body. Look on their site under the kontrol series and it explains it.

These coil overs come with adjustable bodies that are bottom mount. This means when you crank the car on the ground you keep your full suspension travel. The price with adjustable shocks is supposed to be under $1000 which is phenominal. I am waiting for final price and spring rates. CHUNKYBUFUNKY is the member running these maybe he can chime in.

Any compression/rebound adjustment for varying conditions/spring rates?

Great find vettethret! And sorry to steal your thunder... but...

I talked at length to Nick, owner/Head tech guy at Ksport about his kit. And tracked down the shop that did the install on the SEMA car (Chunkybufunky): Apex Motorsports in Tempe, AZ and talked to their owner: Tony and their sales/mkt guy: Jeremy. Great bunch of guys, all of them.

The Kit
The shocks are fully adjustable: Damping is single-adjustable (compression/rebound together) via the top of the shock, load-leveling is gone (no WW spacers needed!) Ride height is adjustable from 1" to 3" drop. The springs however are fixed, they dont use anyone's race spring which would be available in multiple rate, they have their springs custom-made in a fixed rate and length. A few options for stiffer front springs is avialable, but nothing stiffer in the rear is availble. (So i'd call this a 'partial' coil-over setup). According to Apex Motorsports, Eibach racing springs will fit the kit... they had to use stiffer springs for the rear of the SEMA car (due to all the stereo equip. in the trunk), and they used an Eibach race spring in the rear, and left the front stock.

Fitment
For the front, the stock top mount is used. The threaded collar sits at the bottom of the spring (like Ground Control). Ground Control purposely changed the top mount to take some of the rubber pieces out and replace them with stiffer parts to take some of the 'slop' out of the front.
For the rear, the threaded collar sits at the bottom of the spring (opposite of Ground Control).
I'm thinking the GC supplied Eibach Race Spring should work with this kit, as they are 2.5" springs (which is 63.5" inner diameter)

Springs
Front rate: 560lbs/in - 8.07" length - 62mm inner diameter
Rear rate: 420lbs/in - 9.25" length - 62mm inner diameter
So this kit is setup to understeer (Nick said they purposely went for understeer, as it's safer than oversteer). I think the rear rate should be closer to the front (i.e. 600lbs rears with the 560 front), but this could be done via Eibach race springs.

Price & availability
$875 through Apex. K-sport has 10 kits in stock... errr...correction, they now have 9 kits in stock

Summary
I'd say this is a 'milder' kit than the Ground Control setup, front mounts are going to be much softer; and the rear springs are much softer; with a handling emphasis on understeer.
But Dayym! the price is incredible.

So I ordered a set... I'll do a back-to-back comparison with the GC kit and post all the gory details

Awesome! Thanks for the details. What was the price you paid?

Thanks bro, outstanding work. I have been trying to get this info out of K-sport since yetserday. As far as I'm going down, those spring rates are going to be WAY to soft. Looks like I might have to stick with the $1900 set up of ground control and dnd shocks. I thought it might be to good to be true when I saw that price. How long before you actually install them? The last thing I want is a soft spring jamming my tires up into the wheel well. Thanks for all the leg work, I think it may have kept me from making a $900 mistake!

Is your car going to be lowered? I plan on dropping mine 2.25" front and 2.5" rear. Thats why I was looking for the stiff sprigs. If lowered, how far are you going down?

urbanski · #13 (**permalink**) 03-15-07, 03:42 PM

wish you could just do a 0.75" drop

My car is lowered 1" F & R with the Ground Control kit... i'm fine with that much lowering... I'm getting this kit mostly for the adjustable shocks... i'm tired of my way too soft FE4s.

I'll install this kit as is... test it out like that... and then mix in some Ground Control bits!

No prob Urb, i'll check this out... where the car sits at the 'top' of the adjustment... it might just be in the 0.75" range.
