Just picked up my Driftwood Pearl #9 and bought the 100k warranty. Amongst other things I'm doing to the car I wanted to change the rims and tires for better handling/looking package. The salesman told me it would effect the readings on the instrument clusters and could void the warranty. Is anyone educated on what exactly the rules are regarding wheels and rims in relation to the warranty. I've seen a few posts on aftermarket rims and tires and the offsett and size options but bottom line is if it screws up your warranty, why do it?
