I had this idea too, but you'll lose the front/rear movement tunability using the AE hubs since they are wider than the Kyo hubs.

You could spend a few bucks on the B5 kit rear hubs (ASC91414) and experiment.

Those of you that are using Zack Rogers' setup, are you using any anti-squat? I was looking at the setup sheet and I didn't see any noted. I just picked up a used RB6 and I'm going through it and I want to use that setup.

Tighten everything down and be sure everything spins smooth and free.

I was lucky to find a gear cover that is 3d printed and sold by a cool guy on Facebook.

Mount everything up in your buggy, hit the track and air it out!
did you need to use longer bolts to assemble? about to give this a go.

Use a .5 shim under the rear hanger.

I tried a different front end on my car this last weekend for our series race here. I have really liked my car, but with the new Aluminum 502 pivot coming out that I run on my truck, I wanted to try that front end on my 2W. It was actually pretty good. I thought I would lose some steering but I don't think I lost as much as I thought, but I gained quite a bit of stability allowing me to drive it a little harder. For those looking to try something different, just please note the different droop, axle spacing, and parts used on the front end.

I am yet to get a run on dirt with my RB6. It just looks so so nice and clean on the shelf. I have to remember what I bought it for...

Question about sag, or droop as it's called nowadays. Seems like 24mm is about the standard front ride height. I have the medium shock ends and with my front suspension fully extended I'm at 24mm. Is zero front droop the norm or should I have a little? I'm still pretty green but driving other buggys and letting others drive mine, it's handling really good. I think I'd like just a little more on power steering though.

Is Kyosho coming out with there own 3 gear tranny anytime soon or should I just go ahead and built my own? I want to have a extra one all build and ready to go so I can just swap it out on the track, planning on using schelle bearings,MIP diff and out drives,avid aluminum topshaft... Wat are your guys thoughts on this plan?

Do the AKA Evo pre mount rims and tires fit the stock axle lengths? I've borrowed some AKA wheels before and the axle nuts didn't get enough threads on the axles for my liking. They could have been for a Losi or whatever I don't remember off hand.

I buy the pre mounted AKAs and there's plenty of axle for a serrated nut.

Finally hopped on the Kyosho bandwagon. After having a b5m for 6mo I wanted to try something different. I picked both of these up used. Needed some TLC but they are now race ready. Sideways battery is my sons running Tebo setup. Inline is mine running ZR.

Can't wait to test out...

Super clean layout, nice...

I haven't tired any setups other than the Zack Rogers setup and it's excellent, if the tebo setup isn't working try the ZR setup....

Those are beautiful timannn!
My son and I had a rough start tonight but he pulled out a win in novice and I won the B and 7th in the A.

So are the carbon composite arm stronger than the regular??
