Bob, the top hats you have should carry over to the XidaS right? What is the shaft diam of the Koni vs Xida?

What exactly did you like about the Ohlins on the NB? I'm loving mine, just looking to confirm my gut feeling.

Xida shaft is 14mm, shoulder is tapered to 12mm where it goes through mount.
If one has nice mounts already, it's not difficult to figure out a bushing config to run them with the Xida's.

I'm assuming that Xida CS are cut to 10mm to work with NB bushings and top hats.

Nope. Proprietary MCU bushings and a few other bits. NB mount id is actually about 15mm. The special bits ship with the XCS for orders w/o mounts. So you just supply the stamped steel OEM mount.

The new spherical bearing extended billet mounts we're working on will not only fit the Xida, they'll come with adapters to work with 10mm shaft OEM replacement shocks. They'll probably sell for about $300/4. No ETA on them yet. Currently, the extended mounts are a $550 upcharge and only work with the Xida.

Woe, now there is a thought.

That is the same dimensions as Koni. My shock tops have ĹĒ ID spherical bearings in them to work with those dimensions and Iím already running 700/400# 2.25Ē ID hypercoils 6" long in the front 8" long in the rear. If they have enough stroke to work with my shock tops I might could get bare dampers with just the lower adjusting collars.

My shock tops move the top mount up about an inch higher than the stock NB location. Do the shocks have enough stroke to deal with that? I suspect this would eat up rebound that the helper springs are used for and may not hurt that much. Id also need to check how the body lengths compare to my Koni sports to get the bump stops in the right location.

Picture shows a cutaway of my shock tops. Note the location of the 12mm to 14mm shoulder. It sticks all the way through the center hole of a modified NB shock top. other picture shows where the shoulder ends up on an NB stock mount.

You mean shaft length I assume. The shaft length of the Xida puts the top nut about 20mm above the NB mount. Just enough room for the MCU bushing. Probably a tad too short for your use. The Xida-S billet mounts end up with the top nut in the same place. Your stack looks a bit taller. No guarantees it wouldn't be too tall for the Xida shaft length.

Iím not sure how to describe it other than the tires felt as though they couldnít be separated from the ground easily. Same feeling I got with the XIDA's. I didnít feel the limited rebound travel as much as what I felt with Tein setups I've tried but I suspect that having high enough spring rates on the Ohlins helped that problem a lot. A lower spring rate and no rebound travel feels awful in the rear but having very little bump travel feels even worse so Teinís usually get set up with very little rebound travel in the rear to counteract the lack of available shock stroke. Upping spring rates reduces the stroke required for the suspension to take a set in a corner so it helps reduce the run out of stroke feeling where the car transisions behvior at a set level of cornering force.

It sort of looks like the 12mm section is long enough I could put a sleev on it to space the shaft down and have the nut about the same spot relative to the mount as the clubs.

On the Xida-S pictures it shows the front and rear tops have different offsets. I would guess the nut would end up similar location relative to what the one shown for the rear does.

Shock bodies look like they might be shorter. Might need to add spacers to my bump stops to keep tires out of metal bits of the car.

Bob, can you cut and weld your hats shorter. Any fab shop with a decent wellder can weld that od in about 5min a hat tops. Then if your hats can be lowered will the Xida shocks and collars work with your springs? If not I'm sure your koni/swift setup would bring a decent price.

I hav the skill and the tools to do that. Actually I bet I could duplicate the geometry of the XIDA-S mounts. Not sure that my sperical ***** are the same quality or load capacity where they could handle both the spring and shock load like the XIDA-S mounts do though. I don't think those are cheap bearings in those things.

Original version pictured on site. Current version used the extended hat (longer shaft) front and rear in order to be compatible with NB mount.
