Hold the phone... new coilover in town?? Ground Control
 

Maybe Ive just been off the grid too long, but are any of you aware of this??? Been on the hunt for a while now, and this just makes things more difficult!

$1500 for Koni's?

Koni Race (not to be confused with yellows), pimpy hats, nice lower shock bushings, Eibach springs, and sleeves/perches that are still considered by some to be the industry standard.

Yeah, i'd call that a good price. Up to each individual to determine if it's something they want.

too close to xida money

I see everyones point, and trust me, Im on the XIDA bandwagon. Id hate to pass on something tried and true for something new.

Pros to GC : Billet top hat, sperical bearings, dampers valved and stroked( rears ) specifically to spring rate & ride height desires, price point?

Cons to GC: No helper springs, waiting on shock dyno and useable stroke data?

The pros you list for GC are largely built-in on the Xidas, fwiw.

I'm not taking sides, i don't see this particular setup as "EW GROSS KONIS!!!1!!1!one!" but Xidas are a bit ahead of the curve when it comes to development everywhere on Miatas outside of maybe street/stock class autox.

Yeah $100 more then that gets you into Xida's. I see absolutely no reason to buy these. In all honesty when I have my GC coils and sleeves I was not very impressed by them.

I would also consider FMs Fox suspension at that price range, as well as Ohlins

Ground Control is claiming : " The MAX stroke of the front set up for 1" lower than stock package is 8 inches front and 6 inches rear. The MAX stroke of the 2.50" and lower setup is 7 inches front, and 5 inches rear. "

I would be very surprised if this meant more than , the max stroke of the damper, not the max stoke of the assembly.

If i am not mistaken Justin Ross ran these on his TTE miata at one point. Like others have said at the price point why wouldn't you get xida's.

We saw the forum posts announcing these. Nothing earth shaking feature wise. Generic OTS Koni race. All good quality componentry though.

-Steel monotube with a full length aluminum sleeve. Those sleeves will not be an interference fit, they will, by nature, have a small air gap to the shock body. This means they'll run significantly hotter than virtually every other coilover on the market, even low budget steel twin tubes like V Maxx and Tein Flex. This is a big deal for a track suspension. Folks don't often give any thought to shock cooling. The primary reason the Gen 2 Xida increased in diameter over the Gen 1 was to reduce operating temps and increase service life.

- Billet upper mounts use rubber bushings, not bearings. Only the lowers accept bearings.

- Billet upper mounts do no have coaxial spring perches. So they are effectively the same function as OEM NB mounts, just shinier. The extended rears increase bump travel to avoid bottoming with shock bodies that are too long

- No Torrington bearings

- No helper springs. Presumably one could add helpers which would be needed with high rate springs lest the springs come off the perches at full droop.

The equivalent Xida Race or Xida XL setup, NB mounts, no helpers is currently $1799. For that you get a single adjustable, alloy bodied pro level 46mm double digressive piston shock fully assembled with Torrington bearings and Hyperco springs.

They are selling the same thing you could get 10 years ago in a kit. cool. Xidas, please.

Right on. These would have been pretty nifty ten years ago. Not so much anymore. I'm sure some will latch onto the Koni name and go for it, and it may be the best $1400 shock setup out there (and it may not be) but the Xidas are surely worth the extra cost.

Reminds me a cheaper version of my old JIC Magic... don't know if they'll have as much rebound. Will never know, I'm on XIDA 2 now...

2005 called, wants its shocks back

BUT BRO!!!!!!!!

You can slam your car 4" and park so hard

To be completely honest, for the same $1,500 or even up to $2,000 there are WAY better products out there... These GC units look like a typical set of "Ebay" coilovers, and their specs are not very encouraging.

That being said, here's what I see to be "Poor" about them.
1. There is only the single adjustment ring with a tension bolt to keep it locked in place. I've seen plenty of this style strip out and now you have to mutilate them to get the bolt out and even make any adjustments. The "Twin Lock Ring" method is much more sound IMO.
2. There is no Preload capability, therefore preload and ride hight are not independently controllable. This also means that the lower you set the ride height the the less shock travel you have. Which means you'll eventually be on bump-stops or getting coil-bind both of which are a no-no in my book.
3. Even if you don't go low enough to have to worry about the bump-stops or binding, if these are on your daily and you nail a pot hole or raid debris you run the risk of shifting the spring from its perch. This could potentially cause an accident.

The only "Pro" I see to these is the bottom spherical bearing mount which with any higher end coiler you could easily have the same feature included upon special request.

Also just as a side note, you could get BC or Fortune-Auto coilovers built somewhat to your desired specs for $1,300-$1,600

Or buy Xida's for as low at $1600 and have one of the best suspensions for the miata on the market.

Agreed, but I try not to shove one brand down someones throat. I simply mentioned the other two to showcase the point that there are similar products for similar money.
