I dropped the front 10mm and raised the rear 25 and it handled beautifully.
Dont bother buying them the gen 1 leverage ration is 3:1 so every mm shorter than stock raises the rear by 3mm. Buy some 30x6mm steel flat bar and make your own in ten minutes for about five bucks. Stock length dog bones are 119mm long (hole c/c) so make a set 8mm shorter and you have 24mm higher in the rear. I have made dozens for guys in the past all you need is a drill and a hack saw.
These are to lower the bike and are the only pics I bothered taking. Same principal for
raising except shorter not longer. The benefit of making them yourself is for a few bucks you can make different lengths to find a height that suits you.
Once installed you cant see them so they can be a bit rough looking.
Mine before it was turboed.

The first step was to lower the bike. I replaced the stock dog bones with this made from 1/4" x 1" steel flat bar. The linkage has a 3:1 ratio, so every 1/2" added to the distance between the bolt holes will drop the bike 1 1/2" inches. Take the amount you want to lower the bike and divide that by 3, then add that to the stock bolt distance. The stock center to center distance for the bolts is 4 11/16. To drop the bike 2 1/2" I drilled the holes 5 1/2 inches apart. I used a 31/64 drill bit. It's much easier if you take the left side exhaust can off. And put both bolts in from the left side.
