Am trying the Ride Gt300 Body, have you used this body? I used the HD Rip Wing that came with the body and car was very very tail happy off power, switched to Protoform wing and was much better. Do you have any tips for HD Rip Wing wing?
I recommend to use the lip wing for the Ride body. The Ride body has a lot of steering so the lip wing will give more stable rearend.

Why did you put o-rings in the shock when you can limit the shock length with the droop screw?
And what is the difference of running the camber link at #1 instead of #3 on the bulkhead? most setup i see use the #3 spot?

I mean the 2 orings I use inside the shock in the bottom. Camberlink #1 has more camber change, therefor more traction but less cornerspeed. Normally I use #1 for medium traction and in modified. #3 I use for high traction, big track and stock racing.


So cutting the mount, well it give u more steering? or just plant the rear end better? is it only needed for Mod??
For medium traction with the cut motormount the car feels like it has more traction and is more consistant. Looking back to the Snowbirds race, high traction carpet track my car was awesome with the standard one-piece motormount.

Wondering if the fluid that comes with the new gear diff is useful?
Any idea what weight fluid?

I'm not sure what oil Tamiya recommend for the geardiff but all teamdrivers are using oil from 700 - 2000 W


What Oil to run for Front Gear diff?
I have been using 300.000W and 500.000W which both work great. You can also try cleaning gum in the geardiff, disadvantage is that the gear wear more fast.

what the difference between spec r and the tamiya gear diff??
Differences are: internal gear are different, spec-r is 10/22T , Tamiya 12,20
I think the volume of Tamiya geardiff is slightly more.


For those who will get the Tamiya geardiff soon, here some tips how to build it.
At the ETS we were not informed how to shim the geardiffs as we just got them for the race. After the race I have checked all diffs and tried to find the best solution.

First use sandpaper (500) for all gears and sand them down till it touch the whole surface. Then use 3 x 0.1 shim each side.
When close the diff, don't tight the screws too much.
At first the diff feels little bit tight but just run it in, inside the car, same as a ball diff. Jilles
