I am using 27.5 AE oil with stock spring, and J concept goose Bump Tires.
also added the silver anti roll bar from and rear, and ride height at 23mm.
camber is 2 degree front and 3 degree at the rear. stock rear toe in, and eye measure front toe out (i guess 2-3 degrees)
It seems like the inner front wheel will not spin when the steering is more then half way to the end, and the rear end will just spin out and make it hard to exit corner at the desire angle.
here is a youtude video showing me (the green buggy with red wing)playing with my friend xb4.
