It helps with rear traction in the corners. If you need a little less, run a limiter.
Why are you using a limiter rather than adjusting overall shock lengthy at the eyelet
Is it because of where the piston sits in the bore? Just curious

Because once the eyelet is screwed all the way down, you can't screw it down any farther (without damaging threads). You have better control over shortening your length at that point with a limiter, than with a much shorter eyelet. They both work, one is a much larger step than the other.

Looking for a mod setup that uses a full sized lipo. From all the ones I have seen they are all for short packs. Anyone have any info?

Hey guys, I am looking to get an RB6 in the next few weeks. Can you tell me what springs/pistons come with the kit? I am looking to use one of the tebo setups as a starting point which called for pink front, red rear and 5 hole pistons.

Also, I am running a b4.1. How do you guys like the Rb6 compared to the b4.1?

That is great news. Any addons that I should buy when I get the kit? What about spare parts that frequently break?

Here are the three parts I see break:

Rear upper Bulkhead (if you don't use set screws, and/or use the outer hole)
Rear plastic suspension hangers (i recommend the alu versions right off the bat, if funds allow)
Steering rack (i recommend an alu version right off the bat, if funds allow)

Thanks. I don't see a kyosho rack, but Exotek makes one. Is this the one you were referring to ? http://www.stormerhobbies.com/cgi-bi...&pn=EXO1258BLK

There are better. Check out Dias set up from Kyosho site. Have to remember the Tebo set up was pre-release of the car.

Id avoid it. Pre-production car, pre-production chassis, rb5 rear arms, unusual surface conditions at west coast for that event, and I got to talk to him for a good 20 minutes about the car at that race, and I didn't get the feeling he was very comfortable with the setup, or even the car at that point. Frankly, im surprised it got posted at all.

yeah... you can get it there, or directly from exotek. They have some other good bling there as well.

Speaking of which, any feedback on the alu shock posts? I still don't like the alu on alu idea... I don't want to wear the shock caps.
