I have seen a few owners of yz-2's that ran on our carpet track that put a block of brass on the back for the indoor clay track. I keep waiting for someone to go with tungsten for weights. 1 oz of tungsten is 1/3 the size of 1 oz of lead. Your can also get tungsten putty

Do we think there will be a conversion kit for the new car?

If not a kit, atleast the few parts we should be able to get seperate.

I'm just wondering if there is a new chassis required for the CA car, or if we can use the original? Some places say its a new chassis, but other posts i've read say the chassis from the old car can be used.

Jump placed right off the straight + heavy finger = bent chassis.

Trying to figure out if I want to spend $$ on a new chassis or if I want to just wait for the new conversion kit/chassis.

You can mount all the CA parts on the existing chassis as per Mibosport. The dirt car will have different holes in it.

You'll likely need a few more thinks beyond the ball diff and new transmission. Probably a new motor plate, waterfall, and likely a new rear shock tower. Wonder if the dirt edition will need new RF and RR hangers.

Been thinking about this since you posted and I've decided that's not the way I want to go. With the balance I had, I'm fairly certain this would change the dynamics of the setup I have and I'm not sure i'd be able to get it back to how I have it now, no matter how much fine tuning and tweaking I try because the weight would've shifted forward considerably.
I am going to reach out to my paintball family and see what I come up with.

Hi guys, for the YZ2 wheels are those the same size like B5 for the
Front and rear?
And do you know if there's another body that fit or we can only use
The Yokomo body.
Thanks.

For Wheels B4/5 will work but Genuine Kyosho & PRS1 wheels are a better fit due to the smaller hole for the axles. The best aftermarket wheels would be the AKA wheels as they have a smaller hole and their hex recesses are quite snug fitting on all my 12mm cars.

As for lids, you have 3 options that I know of…

STOCK

PENGUIN

AZARASHI This is my wife's lid. Can't speak for the Penguin lid but this one is a lightweight body so it's thin.

I'm the proud owner of a second hand yz2. I love the look of it. I haven't gotten a chance to drive it tonight but I will try tomorrow.

Not sure if I'm running 69/32 or 72/32 but I can verify for you tonight. All I can say is my car moves well. Excellent acceleration throughout.

I am in the process of finding a machinist to bring my idea to life. To hell with the Carpet and Dirt kit. I've run the car on both and I got it
to work BETTER than my RM car as is with just one modification and if it's executed properly, everyone with a YZ-2 will be able to race it
wherever they like.

POWER is going to enhance 4-wheleed weapons this time around!!!
