Mounts may use only stock mounting points, must maintain stock location and orientation of the mounted component, and must be non-rigid.Rubber or other inserts in stock mounts may be replaced with any other non-metallic material.”

Good thing I read this thread because when I perused the prelim copy of the Dec 2011 Fastrack I missed these rules changes.
Washer bottle isn't a big deal to me, was a silly rule to those new to IT but didn't have much benefits or detriments, for my VW Golf. Horn(s) on the other hand, those suckers are heavy and didn't work with the quick release steering wheel so that will be a nice weight reduction opportunity.
Wheel diameter rules needed to change to accommodate newer cars with factory wheel larger than their respective IT* class allowance. It's not like the width was changed. What I don't agree with is the implementation of the rule that allowed smaller wheel diameters for certain cars, smaller diameter than was presently allowed. There is a definite advantage here for those who want to spend the money.
Motor mount rule seems like a good compromise between making an allowance for poly inserts and such and inhibiting solid mounts of different geometry than stock.
