Bet the Audi Quattro rallye cars don't do this to their wheels. :-) Anyone ever tested to destruction a set of Audi wheels before and after these mods to see how this affects their strength? There is not a lot of meat between the bolt holes and the centerbore to start with on some of these wheels. I would be very leery of reducing the amount of material there. I would also be leery of creating stress risers by simply grinding/machining on the wheel. I would want to do something to address that issue too, especially on a daily driver where the wheel is exposed to constantly changing loads over a long period of time. I have seen alloy wheels break from just this sort of modification on a race car. Also have to wonder how the spacer and longer studs/bolts change the loading applied to the wheel, especially in light of the machining that must be done to the centerbore. Just some things to think about. A marginal part works great, until it doesn't. Past success with modified parts does not necessarily predict future performance or suitability. Especially if the modifications are not standardized and uniform. -- Marc Sayer Journalist, Photographer, Dog Trainer (APDT member #062956) Director of Operations & Training - Deaf Dane Rescue Inc.
