Just broke my yz2 for the first time last club racing(rear shock tower) and I've been club racing once sometimes twice a week for the past 4 months. Solid car just can't avoid some hits. Stock up on shock towers and shock shafts. I've broken a shock shaft on my old yok awhile ago but that's it. Also ran my yz4 for the first time yesterday at the same track and I love it .

Correct, when coupled with the rear pills and the chart to get high or low roll centered anti squat and toe settings.

Given that the B-Max rear arms are a direct fit, so maybe the B-Max rear sway bar kit would fit.

You will probably break one of these well before you ever break an arm.

The only thing I find I have to change are ball cups. Mine popped once and kept popping even landing jumps properly. Thinking I will go with TLR/Kyosho cups like I've done on all my cars in the past. Super precise and rarely pop off.

There's a thin spot right behind where the shock tower bolts on that tends to crack in a heavy, heavy straight front impact. They don't break often but you'll eventually encounter a stopped car on the straightaway, etc., etc.

In the 6mo Ive had my YZ2, I've gone through 3 front bulkheads, and several ball cups. Kit rear arms suck (broke first day) but the Bmax arms are super strong. I broke a rear hingepin on a big hit and the arm is still nice and tight. Super durable car!

I haven't broken anything on this car. The kit is solid though. The only upgrade I did was I put the Lunsford Punisher Ti Tie Rods on with the B5M ball ends. I didn't even take a chance with the kit one because they looked alot like the old school Associated and they suck balls.

What on earth are you hitting and are you using brakes? LOL
I race outdoors in packed heats (10-12 cars) and have had a few pretty hard impacts that would've broken my old 22 several times over as well as my 4.2 easily and the most I've had happen is popping cups.

I'm pretty sure broken bulkhead is from hits to the shock tower (landing upsidedown, etc). It starts with a crack then propogates.
