Here’s the thing, you can get fork bushings relatively cheaply but the tools cost an insane amount of money. Here’s a cheaper but highly functional alternative to what’s currently out there.
We’ve all seen offset shock bushes like the ones made by Burgtec, the folks at offsetbushings.com and that one Polish guy’s company called Proshox. Those offset bushings work great if what you’re looking for is just a small geometry tweak in your frame. They’ll make your shock’s effective eye to eye length about 5mm shorter, which can slightly lower your bottom bracket and kick your head angle out a maximum of 1.5 degrees, but probably more like 1 degree for most setups.
