In it's native habitat, aka carpet/turf, you basically add machined shock pistons, enough weight for it to hit minimum (not for grip) and go from there. It's when trying to be beat the square peg of a carpet car into the round hole of dirt racing that things start to get "interesting."

Outback is a high grip indoor clay track. I did about four hours of back to back runs with my B5M lite and my new YZ-2. I ran the same motor and tire combination on both cars. Dirt Web front and Chainlink rear. The new parts on my yz were machined 1.6 pistons on all four shocks. Both cars ran great and my fast laps were almost identical. I liked the extra steering from the yz, and my average lap times were consistently a few tenths faster. I love the way this car jumps. I am sure that I still have time to gain with some more setup on the yz2. Overall I am very happy with this purchase.

I am running the machined pistons, titanium turnbuckles, and a factory battery brace. Otherwise the car is stock. It seems to be working very well on a high bite clay track with a 17.5 setup.

The yz2 works great out of the box! Set up is what you need and that is where others have used weight to help out with traction.

If your track(s) have traction, then the Yz2 is fine. I run mine with Factory RC battery brace and towers, but they're not "needed" to make the car work.

I highly recommend a ball diff, and upgraded pistons like Avids, etc.

Other than that, run the car.

I'm happy to share. I was on the fence about buying this car for some time until I was corner marshaling a couple of weeks ago. There was a racer on the track with one of these and I was so impressed with how glued to the track his car was. Two days later I pulled the plug and bought my own. So far I am very impressed. With a 17.5 setup the car is not dramatically different then my b5m. It feels slightly more agressive then the b5m, but is definitely able to carry more corner speed. As I said previously, I love the way this car jumps and lands. Next Friday I will finally get to race it at my home track which is a medium bite clay. I am looking forward to seeing how it performs on that surface.

Car at LRH was superdialed, until they didnt water for like an hour, then it was only above average dialed. Thinking of adding weight to the rear, like how it drives, dont know if I want to throw the Ymax on there cause other cars were struggling as well.

Worked on Mikes car last night. Dujuan drove it this time and told him what he needed to do to get it even better at LSR. His car looked great as usual. Dujuan was up in Chico today. Hopefully you picked his brain while you were up there.

Pretty much what happens to me, when the mains come around track is dry. Buggy gets really loose.

I was in Chico Friday morning. I was the only one on the track for the entire time i was there. I will have to hit Mike or Dujuan up next Friday at LSR. Currently, my car is setup to your setup on Petitrc.

Possibly need the brass from SMC. Its not that it gets super loose, you just have to change your throttle input, or tell the track owner to groom his track lol... Car is money.

I went back up to Outback this morning. The car was dialed and about 1/2 second faster than my b5M early in the day when the traction was good. It was a bit of a handful late in the day when the traction went away.
