Arrow Moton Club Sport is HERE!

Recently I came across the new Moton MS dampers with 15-level adjustability (up from 7). As a monotube design, the nitrogen pressure can also be adjusted from 87 - 261 psi to add additional lift force for the car so that you can fine tune the handling w/o changing springs.

For the front 22 mm shaft for example, every 10 psi = 5.9 lb of lift force, so you can basically reduce the sprung mass on the actual spring at one corner by roughly 150 lb.

More to come...

I ran club sports on my E46. Loved them, but even after having mine rebuilt, I was having to set the nitrogen levels every 3-5k miles (and each time I went to the track). be sure to get a good gauge setup and check!

wow, thats awsome especially for the rear. The rear damper is further out so the motion ratio is much more effective. You can def cut back on the rear spring rate and use the nitrogen to compensate. I just wonder tho how much the pressure will vary during tracking since its bound to heat up..

Any updates to this? Did you get the club sports installed and tested? How do they compare to the street sports?

Thanks,
ROyce M

Happy to report that the rears are done... some comparison vs. stock.

Very nice setup. Do those disconnects on the front canisters work without bleeding any pressure from the system?

What spring perches are you using for the rears?

You always need to bleed the nitrogen before disconnecting...

Using GC height adjusters in the back.

Fronts are mounted... just need to figure out how to wire the cans.

Man I am sore...

Where do you make the rebound and compression adjusments? Is it a knob similar to the moton street sports?

Can't wait to see where you mount the canisters. I've always wonders where those things would mount.

Can I ask who you purchased the motons and GC parts from? I'm researching a similar setup and I'm on the fence between the SS and the Club Sports. Is it a huge price difference? From what I've been reading it seems like the price is similar just with the club sport I would have to purchase front springs, camber plates, rear spring perches and springs. Am I missing anything?

Thanks for all the detail pics and info.

For Moton, rebound is always adjusted through the shaft/stem. For my set up both dampers are mounted upwards, so the knobs are atop the front strut/rear shock towers.

Compression is adjusted from the cans, mounted in the engine compartment and trunk.

SS is a off-the-shelf kit, designed primarily for the street. CS are dampers only, and you (or hopefully a qualified professional), put a kit together with springs, front camber plates, rear upper mounts, and sway bar end links. Price wise not that much different, when you are already spending $5k on an entire set up.

Interesting! the rear shock is a TON shorter than stock, but the front doesn't appear to be. The top had seems to give the additional travel in the front. I'll be interesting to see how much distance there is between the stop and the shock when the car is on the ground.

No quick disconnects in the rear? I drilled the floor of my car with grommets, but I was afraid of the canisters being exposed under the car on a street car. did you get a nitrogen setup too? they've gotten a LOT cheaper (probably $200 or so now, vs $450 or so when I bought mine 5 years ago)

The rear shock body is shorter, but the total length (mount to mount) is the same. And as you can see the total travel is longer vs. stock, so it won't make a difference.

You still have your N2 set up? Want to sell it to me?

If you haven't got it installed and buttoned up yet, there's a worthwhile check you might want to make:

- drop the LCA and remove the current spring. Reinstall the OEM damper and measure the travel with a rim/tire installed. You already know how far into bump stop you can get, so you can measure the clearance at the top of the tire.

- install the new Moton CS rear damper and make the same clearance measurements.

The risk is that extra travel might cause interference between the top of the tire and the inside of the wheel well, like the original SS Motons had at the front.

The travel with the new Moton rears will be limited by one of three factors: The tire hitting the wheelwell or the bumpstop hitting the damper body or the piston running out of travel inside the damper body.

If it were me, I'd want to know which before I wrapped up the install.

I'm happy to see that you found the right setup for you. I know that you have been looking around. This looks like a great kit.

After spending about 15 hours on the install, the kit is finally done...

Fitment is just like stock parts. The hard part was figuring out how to wire the remote cannisters... but I think I found some decent places.

Pictures to follow tomorrow.

Congratulations! I'm looking forward to hearing more. So, it was four hours fitting the parts and 9 hours finding a place to put the cannisters?

Installed pictures...

Front lines are routed through the side of the strut towers, and the cans are placed at the bottom corners of the windshield.

Rears are routed rough vent holes in the trunk, and cans are mounted at the trunk ceiling. Still need to reinstall the trunk liners and 'beautify' everything a little bit
