Bushless suspension rocks (literally haha) Understand totally your reasons on not going proper wide track, hence why mine is just running spacers! I do think there are gains to be had from proper wide track, but maybe not enough to justify the cost...
Loving the weight saving you're doing, you'll be snapping at my heels soon! I best get the holesaw out again lol.
And 300+(bhp) on the TOTB site...I take it thats with a serious squirt of laughing gas :D
