Sorry, I could not find a listing for a CH12 kit complete with new front end either. The CH12 is there with the regular front end, and the new front end is there as a separate item, but no complete kit. Of course I could have missed it.

Any chance there's a CH12 headed to ND? 
On a car with the new front end what's a good wt diff fluid to start out with in the various damper tubes? My Shur Lube is on back order and if the car should arrive first I may need to use diff lube for the time being.

I would try 30k in the front tube and 15k in the rear tubes. I will need to check on the car to ND. I know that i should have all kits shipped out today that were ordered. Finally seeing the bottom of the pile of orders.
This is a good problem to have.

Hey, need a bit of setup help...
We only run asphalt here with 1/12th... So for sightly bumpy track what ride height? and for very bumpy (VERY BUMPY) what set-up changes should I make... Both tracks are flowing tracks with 1 1/2 high speed straights.
Thanks

I would go with 5-6 mm as jamie said and go with lighter oil spring combo such as a silver spring w/ 40 wt. oil in the shock. The .020 linear springs w/ 10k on the kingpins and you may need to run a little more camber to keep the tires wearing good with the high speed track.

I'm no sponsored driver but I'll be there with the Copperhead 12 with the new front suspension and the Copperhead 10 with the normal front suspension.

Just completed the build of the 'new' CH12 front end on my RR. Its not as simple OR as frustrating as the AE strut front end, but once I got going I couldn't stop. This thing is a dream to build! Like I already told ya J, I don't know how you came up with the idea, but its awesome brah. I love the 'precise-ness' of everything....the carbon fiber and delrin pieces, the 4set screws for droop/ride height, the absence of kingpins & springs, no 'hand-fitting' whatsoever plus the elimination of SLOP.
Still gotta get myself a newly revised CH12 though....
GREAT JOB BRO & keep up the good work!!!
BTW, what we talked about on the phone....got an idea
