I would like to jump stuff. Would these allow me to jump stuff with some tall gravel tires and drive around America's forest roads like a heathen? My AST's are due for a rebuild and this just sounds like more fun.

Actual class 8 off-road truck shocks and World Rally Car shocks are fascinating. Things like adjustable hydraulic bump stops, bypass on both the rebound and compression side. That is basically position sensitive damping. That does not describe any Xida.

That said, Xidas to do handle bad surfaces really well. I would not hesitate to do bomb down some gravel roads but if you're frequently catching air with the whole car and bottoming harshly sooner or later you're going to kill a shock and pretty much everything else in the suspension including cracking subframes. They are just not built for that.

Fresh off a Xida Ace test drive on 300/200 springs.

You guys, it is a freakin' magic carpet.
It is #MaximumCadillac instilled in Miata form.

With the DDA and Pitch settings on 1 of 5 and the Roll on 4, it floats over bridge expansion joints and tree rooted canyon roads. It soaks up driveway gutters like you wouldn't believe. Then you throw it into a turn and the active Roll damping turns it into an S2 Supermiata. If it wasn't for the softtop banging around, you'd think it was a brand new Z4 or SLK.

With the higher ride heights providing a bunch of inherent roll resistance, you don't need the big swaybars. Therefore, you don't get any of the tramlining or harshness from bumps that only one wheel hits.
The soft springs REALLY highlight the capabilities of the Ace system. I think this will be our recommendation for Ace buyers: Go Cadillac on the spring-rates and let the active compression damping go to work. Use stock swaybars for maximum ride quality.

Awesome!
What sensors does the system use/read?

Pitch and roll sensors?
A vertical accelerometer front and rear?

Earlier in this thread you'll see picture of the box with the yaw/g sensors.

Cool beans.
Presumably 3-axis gyro and 3-axis accelerometers.

So does setting "roll" stiff, stiffen the shocks during a rate of change of sideward gees? (i.e. during the transient)
Or does it stiffen while cornering G's are present?

Think there is any way to fit some proper tires? Daily use (abuse) and forest use, road trips, etc. The Paco kit is a bit... rambunctious. Not that this isn't but, ya know. I like going fast and breaking parts sucks. Seam welding and skid plates and all that are an obvious. Thinking a 195. It's an idea. Not 100% on it but the XL's are probably going to replace my AST's since they are trying to bounce me off the road and I don't think I'd mind height again. Driving Miatas is fun kind of no matter what.

Tire choices for an offroad Miata are a great topic for a new thread.

You can get transient wedge with just the rebound adjustable by the computer and the bump fixed, right?

In platforms like the ND with native GPS, you can do that in just one turn on a circuit if you like. The pro teams running DSC controllers with ACE systems do that.

Is the ACE system will be legal in SuperMiata S2 let say, or it's more oriented for double duty and mountain drives ?

EDIT : Street or track cars with ride heights above 5" pinch weld from OP post

Semi active shocks not legal in SPM or virtually any other racing class for that matter. As outlined in the original post, the ACE are intended for street and dual duty cars where the additional comfort and performance are in the budget.

Will you have a car at [email protected] with ACE on it?

NB & ND. We will be giving rides on the street, not the track. Laguna Seca is too smooth to really demonstrate what the Xida ACE are capable of.

Hmm, can you think of an area near LS that would demonstrate it?

We'll drive around on the streets a bit. It'll be awesome. Don't over think it, although I know that is your stock in trade

Question about spring rates.

If the GS is only available with 550/350 springs and is supposed to be a cheaper touring option, then why are the XL spring rates arranged
550/350 Race
450/300 Sport
300/200 Touring.

I would've thought that the GS would be more comfort oriented.

Just trying to understand it and decide whether to go with the GS or the XL in one of the softer rates.
