What I did was get some TL1000R pegs from Ron Ayers - they also sell the spacers. Everything fits right up - no grinding, no sweat. Lowers the foot position the same amount as removing the rubber from the stockers, (about 3/4 of an inch) and you still get rubber. You lose a bunch of weight, and the pegs look like larger versions of the passenger pegs.
Another good point, you are using stock Suzuki parts - I just couldn't bring myself to put something from "the motor company" on my Busa...
There is a thread around here somewhere that has the part numbers, I'll search for it...couldn't find it, so I looked it up on ronayers.com.
