The stock 3.0 degree rear arm mount, part # 7487. Changing this to a 2.5 and or a 3.5 does what to the performance of the car/suspension? How do I lower the front kickup on the b4.1, move spacers to top of the front axle? Thx!!!

Increasing rear toe make the car accelerate straighter in loose conditions, adds traction. In turns it takes away steering and give a more square line. You cannot change the kickup, the shims are for axle-height. In the front you can change the casterblock to decide where you want traction, at entering, even, or exit(30,25,20 degrees).

Dose anyone have the part number for the 25 and 20 degree. Thanks

Front b4.1

Has anyone tried the rpm front a arms yet for the b4.1

I got some on order. should be here tomorrow or Tuesday depending on if I can get to the post office to sign for them.

cain let me know how the fit is.

They look good and fit is good

by fit, I mean they should be really free. as free as the stock arms. I know my kids sc10 were tight.

well, as usual the postal carrier for our street just leaves notices to pickup the package when you have to sign for it, might as well cover up that part where it says they actually tried to deliver the package lol.

So it probably won't be until tomorrow when I can check the a-arms out, or get my escs and other parts.

When the ball diff is is properly installed and broke in on the b4 when you spin just the left wheel after a turn or two should it or should it not turn the rotor of the motor. Im tring to figure out how to tell if its to loose or tight.

I think the flick rule is about 1-1 1/2 turns

Can you elaborate on that please.

you flick the tire while holding the other on.

And a proper ball diff should spin 1 -1-1/2 times after you flick it.
