This is what I personally changed. I didn't do everything in this list because I was coming from an original YZ-2 not the CA. Others may have things I overlooked or didn't use. I used a Factory RC carbon tower instead of the Yok. Only issue with most of my list is it's back-ordered most places.

YOKZ2-500: Ball Diff
YOKZ2-413DM: DTM Front Hub Carrier
YOKZ2-300RM: DTM Tower Brace/Upper Arm Mount
YOKZ2-415SAD: Dirt Graphite Steering Arm Plate (x2)
YOKZ4-008RS4: YZ-4 Rear Arm (To use New Alum Hubs with included bones)
YOKZ2-017: Graphite Front Shock Tower (Flat)
YOKZ2-415RS: Aluminum Offset Rear Hub Carrier Set
YOKZ2-300RUM: YZ-2 DTM Aluminum Rear Upper Arm Mount (Optional)

If you don't have a 3-Gear already:

YOKZ2-302D3M: YZ-2 DTM 3-Gear Case
YOKZ2-503IC: YZ2 Carpet 3-Gear Idler
YOKZ2-304C: 3-Gear Motorplate

I used my original 3 Gear case but you have to trim the ears off the back. PETIT has good instructions on that.

Also, I see different options for front and rear sway bars for the yz2. I'd like buy one front and one rear set for high traction carpet.

Would someone please link which sets I should buy from Amain so I don't buy the wrong ones?

the DTM has a variety of plastic parts on it versus the CA.

I would say thinks like these from the CA would be nice:

- steering rack
- front bulkhead
- front ballstud mount
- rear ball stud mount (sounds like like older style is better)
- rear hub carriers (I use the DTM version)

Idont' recall if the servo mounts are alloy on the CA, but not a bad option.

I ran a B6D ball diff in my YZ2 all day today. The outdrives are about 1mm narrower then the stock diff. The axles never slipped out though. The gear mesh is perfect. There is some side to side slop so I used three 10x12x 0.1 shims on each side between the diff and bearings inside the transmission.

How do the the rp springs compare to the yatabe's. Also, if your running green yatabe in the rear, what rp spring would match up, it seems the spring rate for the rp's is much softer.

Introduces more rear flex, which they need on that bumpy ass surface.

Yeah, we are still all sleeping from staying up, watching and drinking the champagne all night...lol.

Great news - would have love to have seen Lee win it, but 1 and 3 combo in the World's is awesome news. Two of the best in the business that had not won a World's and now, Lee just needs to get his in
