Call Brad Lowe at Lowe's Racing: 989-288-6068. He has no website that I can find, and you might have to leave him a message for a callback, but he probably has what you want on the shelf. From what I understand, he stocks fork springs at least up to .52, and rear shock springs up to 11.0. The rear springs are actually for the PDS shock (but linear instead of progressive), so the ID is slightly larger (63mm v 59mm), but the length is the same, and fitment is no problem.
Also good news is that the fork springs are $80, and the rear spring is $80, include $10 shipping, and I'm respringing both ends for $170.
I ordered them Thursday, got'em yesterday.
