I remember looking at this site a while back, they make some pretty cool stuff.  Easy way to rake your bike as they supply everything.

Check out their fat tyre kits at well:

MMMM could do with the fat tyre kit 

The fatter tyres wont let it handle the same. They look good but the handling suffers from it. Can't have your cake and it too.

those triple tree's seem to use a spacer kit on the bottom tree and from what i can see on his site it appears that they are keeping the origional trail same as cutting the frame!!
at that price you'd want a lot more than just raked tree's!very good feedback..
normal raked tree's seem to be ok to 3-5 deg...i no someone with 10 deg tree's and he gets speed wobbles at 110k's.....
