What up?

If you running Typo's then yes on the Closed cell foam,

I'm just getting back into it after about 12 years away. Back then I don't remember closed cell foam. Can someone explain the difference in handling characteristics between closed cell and open cell? Back then we used to use open cell on everything and we would trim the top corners at an angle. Is that not the thing to do anymore?

Has or can someone do a weight bias test on there 5r with a saddle forward vs 5m with a shorty in the back position ? Thnx

Anyone know what parts from a B4.2 also fit the B5M?

Why wouldn't you run it in 17.5?

Cuz stock is a great class, it keeps it even and really Depends on consistantency and not messing up

The axle being too short should never destroy a bearing with the proper size crush tube in the middle.

The stock axles are too long so they're sloppy. I would guess that's why the clamping axles are shorter.

You may want to shim the crush tube on the inside if you have small OD 5mm ID shims.

I was thinking the same thing.

It will be interesting this weekend at Cactus. I know that many many locals are running the stock class with the B5RM car. I am interested in seeing how well the RM and MM AE cars do at the CC race. At last years CC, AE didnt have a MM car. And even after the Centro came out, the factory stock drivers pretty much stuck with the B4.2. Rivkin was still attending major races with the Centro in mod and the b4.2 in stock. But will that trend continue with the new B5 and B5M. It is hard for me to gauge how well the TLR and K cars do MM against the B5RM locally, because those cars barely exist. So many AE sponsored guys here, that the mains are packed with AE cars. CC will bring out fast guys from all over, we can see what configuration and car dominates. This might be the first "big" race for the 17.5 class since the MM invasion last year.

Generally speaking, closed cell doesn't break down as fast as open cell. Closed cell also maintains a uniform shape and diminishes on tire deformation under heavy loads. For high grip, I feel closed cell is a must but some are using rear open cells cut down to 3/4 width in fronts to actually diminish traction under heavy loads to minimize the chance of traction rolling.

Closed cell also differs between brands - AKA, Proline, Jconcepts to name a few. This adds another variable in tuning and can be very frustrating or rewarding depending on setups. For me AKA takes some time to break in but will last the longest and stays the most consistent. If I am forced to glue up a set right before a race I will run the Prolines because they don't really require a break-in period but collapse quicker over time.

There are more variables to consider but this should give you a general idea.

I'm putting my money on the MM to take 17.5 at CC. Corner speed is the name of the game in 17.5. If They can get the B5M down to weight and figure out how to keep heat out of the motors (locals were actually rigging up fans to run on the motors to keep them cool on there centros and it worked) They will be dialed! I've put my 22 2.0 MM up against the B5 and won in 17.5 on a medium bite track. I can't wait to get my B5M dialed in. I also bought a B5 just in case... Wink Wink

ill give you the consistency part but not the "it keeps it even"
mod keeps it even and fair because you cannot cheat because anything goes. stock buggy is the biggest cheater class in existence

Yes too short of an axle will cause this.there is no room for shims, that is not the problem. the problem is the distance from the lip on axle to inside of aluminum hex is too short, it pinches the bearings when you tighten the wheel. i just talked to nick at associated and they are taking care of it.
