Does anyone make a Front Caster block for the B4 / T4 smaller then 20 degrees?
I'm running on road and would love to find something around 1-10.

Any help would be great.

No sir I have not.
It takes brains to think of doing something like that.

Actually I don't even have the rig yet. I just ordered it in from AEs closeout page. Should have it by Friday.
79.00 for a T4.
 
HUH? 74 bucks, steel man. Guess I got to go check this out.

$74?? Makes me wonder if the T5 isn't too far off?

The only issue with flipping the caster blocks around is the actual pivot point of the steering knuckle.

After doin a quick googlin, here's a link that you'll find handy:

Can anyone explain exactly what a caster block does? I would like to play with that aspect of tuning, but without really knowing what it does I am hesitant to play with it.

Hey Ed, I love the T4 on asphalt. I put a set of speed hawg II's on the front and back and let er rip. A whole lot of fun, and with the BL setup, it is stupid fast! Are you going to go BL in yours?

Caster is a measure of the tilt angle of the steering hingepin. By leaning the hingepin forward or backward, you can change the steering behavior of the car. The B4/T4 are off-road rides. They have tons of negative caster. That means the top of the pin is way behind the bottom. Like this / . That works well in dirt because when you turn it allows the front wheels to bite into the surface and hook the car. Eddy is converting to on-road where that severe of a caster angle hurts rather than helps. You want a more straight up caster. I think on my RS4, stock caster angle is only -5°.

One quick question Eddy (since I haven't bothered to look). Does the B4/T4 chassis have front kick-up? If so, that can make neutralizing the caster a bit of a trick.

Hey Candyman... yes.. the front of the chassis does have a bit up of a kick up.

Thanks for the explaination Candyman. I always thought that caster was the angle of the top of the tire. So if I am understanding correctly... if I want less bite on a dirt track just add more positive camber... more bite negative camber? Thanks my friend.
