hard
med

and tow where mixed.
med center hard outsides
med outsides hard centers.

now I could be absolutely wrong but I would think the hard outside (grey) would work better on faster tracks with looser turns keeping the edge stiff yet more give for the bumps in the middle and the softer med (blue) edges would be better for a tighter slower track?

then again i could have that completely backwards?

so if most people use just the supplied hard foams (grey) with their tires what is the advantage to having these or disadvantage? must be something to those who end up buying these mixes or just a all med insert as well.??

what do you all run in your buggy and why?[img][/img]

so either no one uses foams they buy seperate or no one knows the effect they produce?

well at least lets get a guessing discussion going on it ?

Hey shawn, I saw you at K&M tonight just as we were leaving. I was gonna buy your mbx at fastrak awhile back, just thought i'd see what you were up to. i ended up getting the lx pro but that was the biggest POS i've ever had so I converted it into a truggy and got a hyper like you suggested. been trouble free ever since. later

Hey sorry i missed ya.. yeah the mbx sold quick and i sometimes wish i kept it and converted it to a truggy. i am considering finding a used rolling chassis of a hyper 7 to make a truggy with so that i can enterchange parts when needed. i think ofna is actually putting out a truggy later this year built ground up on a hyper 7 chassis.



as far as the foams go, i am truly shocked not a soul here knows an answr, guess the electric inside guys would know as foams seem a big deal to most electrics racers from whati understand.

i but preglued tires a lot...lol i hate to glue tires ... so i dont what the foams is...... but when i do have to buy them i get soft....

why do you get soft? seems most the local race guys i know use hard. just not sure why....

Foams are more of a tuning aid to try and squeeze out that extra little advantage over the next guy. A harder foam will allow the tire to maintain it's shape. Under acceleration, we've all seen our tires balloon. A harder foam will make an effort to force the tire to maintain it's shape which in turn will give you a greater contact patch with the ground. Also, a harder foam will reduce sidewall flex when turning.

Softer foams would probably be better suited for loose track with lots of bumps. I don't know that they make a huge difference though.

soft hmmm i dont know just what i have ben running our track is not smooth so i think a hard foam will make the tire bounce more then soft.... i may be wrong..
