That d-like pulley looks pretty in there hehehe =)

With the weights and all, do you throw your car on scales? if so, do you have one scale on each corner, and how do you balance it out? Cheers man =)

looks like it has good grip on that surface too... are the R2's quicker than the Kawada's you had previously? =)

[Katsumi]

I have a weight stations but I couldn't figure out how to balance it yet.

I got 4 envelop scale and level.


Set the car on to scale and push down ones then measure it.
Makes even shock preload and don't touch the table.


Yokomo 01R2 slips better than Kawada.
Kawada has more traction and faster.

D-Like Aluminum pulley was lot helped off throttle control and easy to run big sweeper with CS
and direct center was lot help small turns.

dayum, was hoping to pick your brains with the balance thing hey hahaha It's really hard to do hey, every tiny adjustment makes a huge difference, and i wasn't expecting such big changes in weight shift with such a small turn of the shock pre-load ring I never thought about levelling the table tho - must do that next time

I was sorta expecting the R2's to be quicker hehehe Thanks for the info man... going out on a limb here, but do you think the extra weight of the d-like pulley helps keep the front's spinning longer, or reduces it? I'm sort of assuming that more weight on the front one-way diff would help it free-spin longer? but really have no idea - just hazarding a guess

[Katsumi]

I pretty hard to explain about D-Like Aluminum Pulley by English.


Have you try the car stay hold on your hand and throttle on?
It makes rear of the car was going down, other way, tap the brake front of the car was going down.

D-Like thinking gyro for weight transfer of rear to front and front to rear.

May you can catch the how I did throttle controlled from my vid.
Most of the turns, car was switch back after off throttled.

Weight sift to the front. more grip on the front and less weight to the rear then slid of the car.

About makes a sweeper.
Weight shift to the rear the makes throttle on and less weight to the front. then easy to keeps CS because less grip the front.

I can makes quick turn when I changed direct center pulley.

It dose make sense?

Just this bit i am not sure what you mean... i'm assuming you mean to hold the car with your hand in stationary position, and then give it throttle - when you did this, the rear squats down, and when you hit the brakes - the front squats down?

Thanks for the reply man, i could use that extra front weight shift, so i might look into that d-like pulley... just wish they'd make a 42t hahaha thanks man

Exactly what he means.

your car will have more momentum in its drivetrain.

Should increase stability.
