I take it that all this shimming talk applies to other carbon towers such as exotek ones which I have front and back.

Can someone recommend a good setup for OCRC? Too many to choose from.

The Zack Rogers setup works great, very stable and fast. All the Kyosho guys are very approachable, I know Jason Dias and Kuya make time to answer any setup questions, I think Jason has changed 100 things for the current layout

Ok so no shims under front or rear KIT suspension holders equals 2 degrees antisquat? And to take away antisquat shim only the rear holder?

Default 2016 RB6

Any ideas on an update on the RB6 for 2016...?

About to get back into the hobby after 20years and don't want to buy now with a newer version in the pipeline. Loving the look and engineering from Kyosho. I like the rear motor option if needed, local track is lose dirt.

I'm a long standing Tamiya fan but their tech is outdated but their quality is great, seems Yokomo and Kyosho have the same quality now days...

I doubt we will see an updated RB6 for 2016, I would imagine they are working on maybe their next generation of car? They have "upgrades" like the lightweight chassis and other stuff that I just cant see them including in the actual kit itself. I also doubt a new generation of car will come out in 2016, so buying an RB6 is a pretty safe bet

Does anyone have a picture of their lightweight chassis milled out so I know where to mill to put the battery sideways? I don't want to go too far out too deep.

So when you add shims to lower anti squat where are you placing them on the rear arm? Is it between the rear bumper and chassis? Between rear bumper and rear arm holder? Coming from a the AE 5 series of cars I am just trying to wrap my head around the anti squat adjustment for the car.

Also, I heard something about shimming the trans case will have an effect on forward bite or acceleration. Any truth to that?

The shims go on top, bottom or both with the hingepin holder. Kit setup is .5mm top and bottom, you want to maintain 1mm of spacing. To decrease anti-squat you want to run a 1mm shim under.

I am also curious about how it helps certain setups. I think Jason had something to say about that. I am about to add anti-squat to my Kyoshos for our new track.
