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.

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.

thanks
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.

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.

Any idea what weight fluid? and does the new gear diff leak with 1000w in it?
Thanks
I'm not sure what oil Tamiya recommend for the geardiff but all teamdrivers are using oil from 700 - 2000 W

I think I will start with a 4.5T motor in Andernach

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.

Thanks~
I'm not familiar with 17.5T but I quess most racers gear them around 3.5 - 4.0 . I know from my friends 416, he uses spurgear 87 and pinion 44 to be around 4.0 gearing.

Used your setup from latest ETS round, car was awesome on it. Only thing I changed was 3mm steering spacer and kept C blocks in the front, thank you again for posting

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?
Thanks great! 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.

In a post quite a few pages back a question was brought up about changes made for stock racing. You said you would go to stiffer springs and about it. Could you explain what the stiffer springs will do to the car? And would you also want to start with a little thicker oil? What springs should I switch to. Currently running blue and yellow Tamiya springs with 425 weight oil.

I know there is a chart but can't remember where it's at for all the spring rates of all the manufacturers. Anyone have this?
With stiffer spring I recommend, HPI gold and Pink. Also shock oil around 600 should work good. I'm not sure about the spring rates.
