Scott could you give me the part# for the 23t pulley?
With this pulley how much different is your front tire diameter to the rears? Thanks

I want to minimize rear tyres' wear rate. I'm still using stock pulley setup with 3mm split. I feel the car is becoming harder to drive especially almost the end of race. Would 23t pulley help ?

I cannot use 16/19 coversation..... no short belts in my LHS.

I really appreciate your inputs for 23t pulley ... thanks .
If you still would like to have the 16/19 setup a Traxxas Nitro 4 tec belt is the right size for the coversion. The belt may be a little stiffer but it is the same size. Just so you know.

I know putting Traxxas parts on a mugen is like buying a Kraco radio for a Vette.

I was incorrect. My MTX 3 had a 24t pulley. I know Mugen has made some 23t pulleys as the first batch of the MTX4's had 23t pulleys. (My kit came with both 23 and 24 tooth pulleys). If you contact Mugen directly, you should be able to find one.

I dremel the brake pads and plate so, the disk would roll freely. Try that one.

The other thing I noticed on my friends car is the disc. It won't move freely left and right. I have to make a bigger hole.

that actually may be the majority of the problem.. so if the disc is at an angle then it doesnt align itself straight...

I used some 80 grit sandpaper and just sanded the pads down until they didn't drag on the disks. You may have to take off quite a bit. I know I was there for quite a while.

I did sand them some to make sure they were smooth and even but it sounds like I'm gonna be sanding some more along with checking the holes in the disc for rough edges....

thanks for all the info guys..

Also, the screw that hold the rear body post to the rear bulk head make sure it is not too long other wise it will press the rear bearing of the diff and would also, cause drag and possible handling issue aswell.

depends on your engine none will be the same so it doesnt mattter how many shims you have all that really matters is the clutch gap and how tight you have the spring
