To much flex is a bad thing. The chassis will snap back violently. And you can make minimum weight with the stock chassis in mm with out doing anything crazy with upgrades.

Correct, I had a buddy with a Tamiya that was fighting that. He ended up making a CF brace for the entire chassis.

Go on Avid's website and u can choose which bearings u want for the rb6, which in turn will give u the sizes needed.

either of you guys try running the standard chassis without the chassis brace? not just removing the screws but completely taken the brace off? I tried it and I had a ton of side bite but then the car became a diving board. sometimes awesome and sometimes not. I'm curious if this is the same sort of result.

I have completely taken the brace off. I liked it a lot but like you said it dived in to the corner. But it gives lots of side grip. Works well with dirt webs!

No just taking the bottom screws out for me.

Just built up an RB6 and my rear shock springs are rubbing against the camber linkage. Manual calls for a total of 5mm of spacers on the top shock mount before you put the shock and nut on. If i swap 2mm to the other side of the shock eyelet, it clears it fine. I'm using the 0 deg alum hubs.

Is this ok? Did I build something wrong or is this normal when you set up the rear camber links certain ways w the alum V2 hubs?

Thats what I figured, but wanted to be sure. Thanks.

I'm switching over to KYO from TLR, very excited already by the quality of the build.

Awesome! I love my car as much as I tend to tinker on it and get it way off wack. Every change is noticeable.

Yes but you'll need a lot more than you're keeping. Shocks. Turnbuckles. Towers. Arms. Quick change. CVDs. Body. Spur. Battery strap. Chassis. It may not seem like a lot but it will be expensive with the shocks and chassis alone.

Ok never mind I was hoping the chassis would be the same. I know you need long shock body, Arms and CVD and everything else is the same.
