GR with Xida on Touring Springs (250/250). This is about 140mm ride height. Most cars will be able to get down to about 130mm on Touring and 120-125 on 500/500 or 600/600 Race.

Wheels are 17x9 +48 Gen 4 6UL. We stopped making these wheels in 2017 and they are sold out. Working on Gen 5 wheels for early next year.

949: That looks great. A couple of questions. What is your measurement of the OEM ride height? How does the ride quality compare to OEM and B6 (OEM springs)?

Thanks.

Pinch weld height, OEM jacking points with 25" tall tire. I'd also point out that how low you run the car is not limited by Xidas. They are designed specifically for the car, fronts have adjustable strut flanges. You 'll be able to use every last mm of space before the tire starting hitting the tub. The lighter the car and stiffer the spring, the lower you can run. We often get questions about that from folks coming from China/Taiwan made 2 piece coilovers with limited travel. That's simply not an issue with 1 piece shocks that are the correct length.

Touring springs (250/250) absorb everything far better than OEM. All harshness gone. The overall ride is a tad firmer due to the slightly higher spring rates. Big difference between Xidas and Bilsteins is the response to small pavement imperfections. The Bilsteins don't move much until a bigger bump is hit. So the car often quivers and jiggles over most pavement. That's gone with Xidas. The B6 work well on bumps that aren't sharp edged but will still run out of damping when the car is pushed hard. So they have a relatively narrow window where they work well.

Even with 500/500 Race rates, the ride is never harsh. That ride quality and versatility is really what Xidas are all about and why they are the gold standard in the Miata world.

Why different spring rates (touring pack) between GT and GR86?

Total weight, weight distribution and motion ratio differences. They're different cars.

I thought older ones got lower rear MR, that’s why I expected higher rear or even rates.

How much total travel front and rear?

Have you visited the website link we posted yet?
More specs there, including stroke 145/115 and everything else

Damn I’ve missed the FAQ

“Be open minded, be willing to experiment, look at your data, test”

Great words ;)

Is this F/R or R/F?

Sorry

GT86
250 front/200 rear
500/500

GR86
250/250
500/500

Those are our recommended spring packs. As with any of the Xidas we offer for other platforms, you can opt for other rates. Call or email us and we'll go into more detail for any given project to customize if needed.

Thanks for your continued support with this platform.

I will be installing a set of your camber plates on my Feal 441+'s this weekend.

I'm eyeing a set of these for when I go to Street Touring Whatever as soon as the new car is competitive in a class.

Those that I've talked to in STR, have been much happier with a stiffer rear spring (50 - 100 lbs more) at autox.

Shop video with some extra info about Xidas. Let us know if you have any questions!

Nice to see at 1:57 in the video that you explain that the bottom bracket adjustment is intended to fine-tune the extents of the suspension movement, not "tHiS iS HoW yOu AdJuSt RiDe HeIgHt" like frequently recommended elsewhere.

Thanks. The difference here is that most folks talking about ride height adjustment there are talking about a 2 piece shock that has a hollow adapter (bottom bracket) at the bottom. The actual strut cartridge in those stops well short of the strut flange.

So with 2 piece shocks that are intrinsically too short, the owner needs to decide if they want to compromise bump or droop travel, because they can't have both. Thus the "adjust ride height here" narrative. It gets confusing, that's one reason we made the video. To highlight the benefits of our configuration. Watch the 2 piece video linked in the description to see more on that subject.

Xidas are a 1 piece full length shock with a clamp on strut flange. In our case, the shock actually extends well below the strut flange. Different beastie :)

Yup, totally noticed that!

Kits from the next batch on sale. They'll be here early December

Next batch due here first week April 2023. Taking pre-orders now.

Didn't see it listed on the 949 site, but do these take the >=40mm shaft diameter hit for NASA ST/TT5?

Page 14, 6.1.9 point 7

The 86 Xida inverted strut is 43mm shaft diameter

I was afraid of that :( Thank you

edit: wait, strut diameter is 43mm but what is the shaft diameter inside the body? Sounds like it might be legal... if so...

43mm is shaft diameter.
Strut casing is 55mm.

Who or what is this NASA rule intended to penalize?

Seems like it is some rule that has stuck around since the letter classing days, I am not sure who angered the powers that be to set it in motion. What a pain.

Yah. For some platforms, everything is inverted. For other platforms, there is nothing available that's inverted. Dumb.

We're not going to downgrade Xidas to avoid the hit though. Ironically, the original single adjustable Xidas for the NA/NB Miata were built to get around the NASA rules penalizing reservoirs and multiple adjustments. But switching to a standard small shaft strut is just too much of a functional compromise for everyone else not running NASA.

Yeah, can't blame you in the slightest there. I was really happy with the Xidas on my NB :) Maybe when I get a wild hair up my ass to add power and play in 4 again.

How close is this to stock ride height? Can these go to stock ride height?


How is clearance with the 17x9 +48 and 245/255 40 tire? Thanks!

For reference, stock ride height for 2017+ cars with showa base dampers is 155-160, PP Sachs is 150-155.

Older cars should be a little higher but I’m not sure.

Stock ride height can be achieved if that's what you are looking for. Full specs and details on the website product page. I'm not sure what you are asking for on tire clearance. Do the tires hit the shocks? no.

If you are asking whether the shocks allow the tires to bottom out against the body work, the front struts can be adjusted to do that. Obviously you want to adjust them where the tires do not bottom against the chassis. The default strut length adjustment in front is optimized for 255/40 on 17x9.

That answers all my questions, thanks!

Although they are out of this pensioner’s price range, I still drool over these.

"Buttery everywhere"

sigh

Gorgeous.

Update:
16mm internal shaft diameter not subject to NASA ST points penalty

9 kits coming next week, Swift springs, camber plates, everything in stock. Custom rates available. If you aren't sure if the 500/500 race rates are right for your build, contact Ed and we'll get you dialed in

Mine showed up, half way done with the install (complications with something else). These things are a work of art.

Figured I'd toss in a few pics
