This is not really a mod but figure I post it. After organizing a drive down in the Bay Area , CA, I was driving back over the bay bridge and found some debris in the road. I just side swiped it enough with the rim to take a chunk of the lip and of course lose air pressure. I limped across the bridge and survived not getting rear-ended. At the time I did not know you could fix rims so I ordered a new CSL rim. In later years I have had it fixed along with one of the rears and another front rim. Joys of driving on crappy California roads. Below is the spare CSL rim now in case I need it.
