it's not the chassis. i had this damper hooked to a custom made cross bar on a PN motor mount and all was straight and true with same bearing shim. i was hoping that moving it over to an all atomic parts rear end would simply make it all fit without issue however that is not proving the case for me.
Interesting... perhaps you may have received a defective product. Maybe try reaching out to them to see if they can offer a replacement. Is Sai Tam still representing Atomic for North America?
i don't have a setup board but will be at remnant Thursday and maybe someone there will. if it is indeed a miscalculation on the hole in the support arm, i can always drill a new hole provided the correct location is sufficiently off to accommodate it. i'm not afraid to drill into the mount arm. if i had aluminum stock and better tools, i would just make a new arm myself.

Hi Arch, Look at the pivot shaft hole in relation to the T-plate pivot. The hole should be in the middle of the four holes for the t-plate. Mine was perfect. If that is ok, the problem is probably somewhere in your SCS. Hope this helps.
with mike keely's careful eye, there was a couple things he did and i watched that took 90% of the tweak out of the mount.
1. the t plate end needed to be sanded down so it wasn't bunding up on the swivel mount bar. the bar is recessed for a t plate but VERY tight fit which was causing my t plate to be tweaked.
2. bent the damper support arm up with a lever arm just a fraction.
3. disassembled the damper. regreased the damper shaft. tightened up the loop so it pinched the swivel catch pin.
all of this greatly improved the tweak in the parts but did not 100% eliminate the off center nature of the damper. i plan to bend up the damper support arm a fraction more to bring it into as close to perfect alignment as possible. if you have the tools, i recommend slotting the screw point to the motor mount so you can adjust the damper post location left to right. i don't have the fine tools needed for this. honestly disappointed at the lack adjustability of the damper support arm. i'm sure this motor mount is much better suited for brushless motors than brushed.
i drove the car in a 10 minute race tonight and came in 2nd so the parts combination are working for me but not 100% there yet. i have till january 11th to fine tune everything though.
FYI, all of us that (were) using the SCS at our track don't use the spring at all. Just some grease. Some of us have gone back to a traditional disc damper. Also, most of us have gone back to the older PN MR2295 model motor mount as we find that is the best mount for rear grip. We were using laydown models, etc... Note we are 98-99% brushless at the track.

Ray, I have a file that is small enough to make a slot in the top mount arm were the screw goes through. This would give you some adjustment if needed.
thanks for the offer. i'm leary to use a file and enlarge the opening making it wobbly vs. drilling another hole to the side and filing it smooth between.
