Yea, ceramic balls, and thrust if you don't mind spending an extra $10. You'll shocked a diff can be so smooth.

Speaking of rebuilding diffs ...has anyone noticed (of those that went from carpet to asphalt), that on asphalt the diffs seem to stay smoother longer? ...I was totally expecting the oposite to be true as in would seem the dirt and stuff from asphalt would tend to make the diffs crunchy sooner ...all I can think is that I guess carpet fibers tend to "muck up" diffs sooner than asphalt dirt????

It has to do with the higher traction levels. Nothing to do with carpet fibers versus asphalt dirt. The diff gets worked more on high bite in a more aggressive way.

Jeff/Brian M/Sushi >> How much of a "must-have" is the 4mm chassis for carpet (club racing). Sushi - I am talking about Rain City if that helps...

None. Just check out Jim Herrmann's or Brian McGreevy's setups from the Novak race. Stock Carpet kits from the box just add the low roll blocks. Which even then are not totally necessary.

Hey guys, I have a body mounting question for you. I am planning on mounting a Protoform Nemesis body on the RDX. I was wondering if there is a work around for the rear body mounts. The mounts are almost inline with the wing mount. Any help would be appreciated. Thanks guys.

Corally came out with an updated rear body post plate about a year ago that's got several holes drilled in it so you can mount your body posts closer together and avoid the problem you're having. I imagine by now, all the new ones you can buy have the updated mounting holes.

Yup, my car still works great witht he 2.9mm lower deck. On carpet with foams I always run the thicker upper deck... that seemed to make the biggest difference. The 4mm lower deck is actually milled down to 2.5mm where the bulkheads sit, so it lowers the roll center another .5mm then the stock chassis, and it's more rigid. I know most of the team at carpet nats actually ran just a stock chassis. Daygers car I think was pretty much a bone stock carpet spec kit with a lowered front tower, and low roll blocks.

This is what I run here at Rain city. The carpet is CRC fastrack and we use Jack the gripper as traction compound.

Front:

-Oil: AE 60wt
-Pistons: Tamiya 3 hole
-Spring: 30lbs
-Shock position: one hole in from outside on tower, outside hole on arm (Assuming you are using the old arms. On the new arms it will be the inner hole)
-Camber link position: upper row, outside hole
-Camber: -2 deg
-Caster: 4 deg
-Toe: 0 deg
-wheelbase: mid
-Ackerman: stock
-Droop/uptravel: 2mm up
-5mm ride height
-low roll blocks with 2.5mm shims on them to space the arms out.

Rear:

-Oil: AE 40wt
-Piston: tamiya 3 hole
-Spring: 22lbs
-Shock position: outside on tower, SRC x-long extension on the arm
-Camber link position: Top row, outer hole on tower, and middle hole on rear hub carrier.
-Camber: -2 deg
-Toe: .5-1.0 deg
-wheelbase: mid
-5mm ride height
-Droop: 2mm up
-low roll blocks

Other:
-Front diff
-75% suspension arms... or the new ones
-Narrow hex/wheel adapters all around ( you might have to trim the front knuckles a tiny bit to clear the wheel. If you run a std wide one up front that will result in more aggressive steering)
-lowered shock tower (not the "drilled" std shock tower to make it lowered)
-Parma Cyan fronts and Parma Magenta rears trimmed to about 56-57mm. Try to keep them all the same size... the fronts tend to wear a little faster. If the stagger becomes to big the car starts to push and do weird stuff.
-3.4mm upper deck, 2.9mm lower deck.
-Parma alfa body, stock wing.

That should get you guys goin. If I missed anything let me know.

-Korey
