im building my rear gear diff now, im a little confused of what kind of oil that has 35 wt for the diff, i've been looking around online but cant find one, does shock oil will work on diff in my tc6.1 since i have a couple laying around, thanks...

found already the answer in the manual, sorry i should have read it first lol...

Just got my car and staring to build. What cam do you guys recommend for asphalt parking lot practicing and concrete racing?
Any other tips on the build is appreciated.

what length are you guys making your shock shaft?

I don't recall the actually measurement. For the rears, I screwed in the shock end all the way, minus 2 threads. For the front I when in all the threads.
Your droop screws will ultimately control how far your suspension goes down. As long as the shocks are long enough that they don't limit travel before the droop screws you'll be ok.

Actually its important to make the shocks all the same length. I used calipers to measure mine and make them all the same. I think it was 63mm from top of the cap to bottom of the mount. I could be off the measurement a bit but try your best and make them equal.

Cam???
Do you mean camber?
Use the setup suggestions found in the manual. This is a good starting point for the TC6.1 and the new shock shafts are long enough for "normal" droop settings as you won't need to leave any threads exposed. just screw the ball cups to the end of the threads and you will be fine.

50wt Associated shock oil on the rear gear diff.

Racer edge putty on the front.

Why? I can see this being important if we didn't have droop screw.
I used calipers when I built mine as well, but I really don't see the need for it.

In the manual under the front spool and rear diff building. Options for setting the cam are low/mid low/mid high/high, depending on surface traction.

^^^^ I think he's referring to diff height.

Yes. What is a good starting point? Manual says mid-low. It that good for asphalt parking lot?

Got it. Had a brain fart.... When with standard set up in manual

Hey Kim, he found the magic manual...now all is clear.

It is important so that at ride height, your pistons sit at the same position in all 4 corners. The piston height has a bit of an effect on how the oil flows through. Having all shocks the same length ensures all 4 shocks are "equal" which should make the car more consistent.

This also allows you to set your shock collars at the same height L/R and can help you identify when your car might have some tweak.
