I spend a lot of time on TC5 diffs. I check them almost every race day, but I think the key is to make sure you are putting a good amount of diff grease in the diff on build. Also make sure that you are not over tightening diff. The diff should be pretty smooth and should not bind in any way. Because the diffs are open they tend to dry out.

Usually when diff parts melt it is because the diff is slipping too much causing heat - mleting plastic. I usually tighten the diff screw until it bottoms out and back it off 1/8 too 1/4 turn and fine tune from there. Looser is smoother but it wares out faster.

Anyone running the Mazda Speed 6? How much different is it from the regular Mazda 6?

Are a 1 way and a slipper spool the same thing? If not whats the difference?
A one way allows the front wheels to free spin off power, then locks up when power is applied. This allows the front wheels to keep rotating allowing the car to steer. When power is applied the one way locks up giving the car more pull out of the corner. The one thing to remember when using a one way is the brakes are only in the rear. If you are too aggressive with the brakes, the car can spin out easily. The spool has the pull of a one way out of the corners but gives four wheel brakes for more stable corner entry. The slipper spool adds some give over a standard spool. This give takes some stress off the drive train that occurs when using a spool or a one way, Hope this helps.

Speed 6 has more aggressive steering while still being very stable. The R9R has even more steering but at the high price of very little rear grip. If you can make some mechanical grip through set up, it might be ok.

try this if its really really good high bite asphalt--use the R setup from the manual and make a few changes

change the downstop (droop screw) to 8 all around

shocks -the 3rd hole from center out - all 4 shocks

remove the front sway bar-keep the rear black one with the one dot mount

camber front = 2

camber rear = 3

apply tire compoud -Jack "The Gripper" on all 4 tires

Check your lap times, let me know if this helps or not.

So which do you prefer Speed 6 or regular 6?

With that being said......I gear my Trinity duo 13.5 at 100/41 which is 4.88 this is on a 100 x 50 track
For a Trinity 17.5 duo I gear at 100/45 which is a 4.44
I use an lrp speedo with full punch.

our track is rather small, the carpet track is probably that size, the asphalt track is maybe 85x45,its inside an oval, would i be okay with that gearing?

thanks,

If your track is smaller.......start about 2 teeth smaller on the pinion. Check the temp on the motor after a few mins to make sure its not getting too hot.

On the R with carpet and rubber the stiffest I have used are the coppers. Softest I have used are the greens which are the softest. The only ones you might not use are the yellow's and the whites, but it's cheaper just to get them in the kit. One kit should do you and figure out if you need multiples of any of them.
