Every time I ran at Rev's, there was way too much traction. CP was better all around except for the bumps. I am sharing what worked for me, and it seems to be about the same for you.

I am running the 24t side pulley in front.

You don't have to run a shim at the bottom of the shock, but I would. If you use one then get a shim that is 1-1.5mm thick. I do run a 4mm shock tower, but mine is only 2.5mm thick at the bottom where it bolts on. This keeps the body mounts and shock angle the same as using a stock tower.

I have run 10k, 30k and 50k shock oil. What the other people have said about the shock oil differences is true. As a general rule of thumb, the more traction, the heavier diff oil.

All depends... on the track conditions and setup of your car, two weeks ago went up to 30k oil with o-rings on the planetary gears (just to make it a little stiffer). That day, the car with dark blue springs and 40's everywhere was completely dialed. Next weekend, needed to return to light blues, 40's and 10k diff.

Have here a 50k oil bottle.. but seeing how performed with 30k oil on diff I don't think I'll need it on the future unless I find some extreme track conditions that warrant the use of such thick diff oil - probably I'll go solid rear.

Thanks all!

I got the mugen option shock tower. I will try it this weekend.

The reason for wanting changing the shock oil for 10k is that the car is pushing. I have rear end traction now so i was thinking that changing the oil would help with the turn in.

Any other suggestions?

Are you talking shock oil or diff fluid? If you are pushing, you should go higher in viscosity, not lower. Lower viscosity will allow the wheels to "diff" easier, hooking up that end of the car more.

Upper mounting shock location need 2mm - 3 mm shims when using 4mm rear shock tower. In my case I use 2mm shims that comes in the box ( for rear upright / rear upper link ). Twist the shock absorber to make sure it doesn't hit the carbon fibre. You could add 2mm shim at lower shock position if you feel the shock position is not straight top to bottom.

30k diff oil or 50k diff oil ? ask A class drivers who play together in your circuit.... 30k is mostly use for medium to wide open track while 50k is more suitable for technical track.

I just milled the rear of the shock tower down 1.5mm where it mounts to the rear cross-over block and that also moved the body mount forward. This kept the strength of the unit and leaves everything in stock locations.
Simple fix.

Are you guys using a total of 3 5x8 bearings with the MTX-4 clutch bell? I was looking at the manual and it shows 2 5x8 bearing being installed on the inside and 1 5x8 going on the outside.

What rear diff oil is best when using a one-way?

The track has a sweeper on to the straight but has a fairly tight corner at the end of the straight (which is still high speed) then another straight after. Also has a tight hairpin in the infield. The traction is ok but the track is quite rough.

Will a tighter diff give me more traction or will a looser diff.
Please explain.
Also what shock setup would you recomend for a bumpy track?

Thicker diff oil will make it more like a locked rear (more forward traction) but hurt you in the turns ( not as much steering).

Thick shock oil for smooth tracks and thinner oil for bumpy tracks.

Yes three bearings.

Yes, use three bearings like the manual says.
