To answer your questions, yes to all of the above. I have 4" on my swingarm and tried to lower 2" and every small bump in the road caused the rear tire to scrape.You can pull your tubes thru the triples but you need to adjust the rebound to your wieght and style. Hope this helps.:cheersSkyhighsami said:If you lower it 2 inches and stretched it 4 inches then would you have a problem with the tire contacting the tail piece? Also when you lower the rear 2 inches what did you lower the front and did you just drop the fork tubes through the triple tree? At what point will the fork tubes contact the fairing stay?
