I just bought a tri-z rolling chassi the other day and i'm trying to find a front fender and a front brake caliper. I bought the frame so i could do an engine swap with a wfz450. its gona be crazy fast. the four wheeler was running 96mph when i bought it and it had a slight hesitation off idle. ive been tunning on it and it still hesitates off idle but i ran it the other day and it ran roughly at 108-110mph. but im pretty sure ill need a front brake on something this fast.
