haha yeah. my dad is running my old mtx-3, and boy does that thing lack in the steering department. the 3's are well known for their understeering
While my mtx-4r is steering very nicely hehe

I kind of have this question too, but I think I have a basic understanding. As I understand it, the spool has less steering everywhere, but gives you the same corner exit speed as the one way whilst giving you braking stability. I assume therefore that if the track you race on flows and doesn't have many heavy braking zones then go the one way, if the track has a lot of big stops especially ones where the car is turning into the braking zone use the spool. Personally I built my car with a spool and I've never changed it but I know people on here have had success with the one way as opposed to the spool

Now, can someone explain what changing the rear diff oil does? I know people thicken it up when traction is high, and I believe the effect is that you can get on the power earlier in corners, but does it affect steering? what about when the traction is medium (e.g. non vht)?


oh and yeh, kyosho shims inside, mugen outside. My clutch has always been great with this combo

Spool up front will give you less turn-in steering, but you can get on power earlier and it will pull you through the corner nicely without the rear stepping out. So you'll have more on-power steering and a very stable car. On slippery track (low traction, dusty, wet) don't use spool, the car will not want to turn and will be slower overall. Medium or high traction, go for the spool instead of the diff.

Rear diff oil - generally, the less traction the track has, the lighter oil you should use. More traction, heavier oil. Heavier diff gives less turn-in, but more on-throttle steering and of course more forward traction. If your diff is too heavy for the traction, the rear will want to step out when powering out of corners. If it's too light, the car will be unstable under braking in and understeer while powering out.

I always ran a one-way on my home track which is med. sized flowing med. grip. I went to a very large track with high bite and put in the front spool cause that's what everyone else was running. I absolutely loved it. Car felt very fast everywhere and I could actually use hard brakes when I needed it. I liked it so much, I decided to try the spool on my home track. It felt absolutely horrible. I felt like it had no corner speed at all and I was considerably slower than normal. So basically, I would say to try both and see which you like better at whatever track you're at. It was as obvious to me as a slap in the face!

make sure the od of your shims no matter what brand is smaller than the od of the bearings, ie, a 5x8 kyosho shim works the same as a 5x10 mugen shim when using a 5x8 clutch bell bearing, a little dremel should do it so you can have a 5x7 or 5x7.5 shim instead!

AE has some 5x7.5 shims, you'll only need to sand the inner part so it is 5.1 or 5.2x7.5 otherwise it won't fit in the crankshaft

happy racing!

Wow, that's looking sweet Chooky!
YOU're almost up there with TomB for Bling Factor!
Are you shure that it' not too heavy?
It's nice of you to include a pic of what a clean filter looks like so that Wally will know what to buy when he's next at the LHS!

BTW the only thing that you did wrong was to use a PINK arial tube instead of a Mellow Yellow one!

Haven't played since the last time in the mountains.

I have a question though.

I have a kawahara CF side brace which came with 2 rubber O-rings.
Are these necessary to use between the brace and bulkhead?
Will it tighten up enough using the O-rings to have no movement/flex?
Or do i not use them at all?

i don't run them in mine if you run them it allows flex which may increase chance of gear stripping, see you at the gong
