Love all the traction I can get and then some, though, I think on the MM setup, rear traction gains are not as easy to come by when you need it. To the point that the need use of stock foams may be the needed route to go with that setup more often than not. Lots to play with/try, and for sure plenty of things to learn. LOL. Fun either way for me. If being fast was easy, we'd all be the fast racers. LOL.
At my local track I'm the only one that run mid motor and always run open cell "stock foam" inserts I'm in the winning streak since I got my KYOSHO RB6.. I got 2 DNF because of the darn ko propo EX1 KIY.. Darn thing when the connection gets dirty they start glitching...

At our track, the firmer the insert the better in almost all cases, except for that first run. After that, it's golden, especially with red aka foam and aka super soft tires. I run ghosted fronts and pretty mowed rears since the track is wet a lot recently, but even brand new tires are awesome once they get that first run edge out of the red aka foams. I find myself replacing foams, especially in front tires, due to the low tire wear and how good tires work when mowed right now.

Gotta tell ya after being Mr AE at our track, making the switch to the RB6 has been amazing. Running mid motor has made me and especially my 12 year old son a way better driver at the track. It's just so darn easy to drive.

Then again having team manager Joe Pillars in the pit, getting us dialed in helps

Ha ha,

I was the first to switch to the MM at mine and while I'm not on the winning streak, I do love the RB6. Very happy to have made the switch to it.

I hear ya for sure,

In the RM setup, I always liked the firm foams more, though our track doesn't like the SS compounds as much. I have tried them and the Clay compounds have been the preferred compound. Even the softs don't fair as well, but can be ran.

I wish our track would only take one run to get them dialed in with new foams and tires. Takes a bit more than that, but when they're good, they're good. Consistently good. Having gone to MM though, I think there's room to play with the rear foam a bit to help rear grip when needed. I'm still playing with the stock foams, but for now, they seem to help me. Not always the faster setup, but a comfortable and predictable one that could be of use should track conditions be as such that they're needed.

Just rub it in a little why don't ya. LOL.

Joe's a cool cat for sure. Wish I had him at my local track you lucky dog. Glad the cars are working for you and your son. Well worth the extra cost if you ask me.

Rear motor or mid-motor?

For rear I would start with Tebo's 2013 CRCRC setup and for mid the World's setup.

Tebo MM setup is for high bite... This will not work on a low traction track..

I'm pretty sure 1mm = 1 degree... I shim the RR suspension hangers 2mm and made the hinge pin straight flat which give 0 anti-squat... RB6 has 2 degree stock anti-squat..

Any suggestions on a mm setup that works on a low-medium grip?
