I believe Summit charges only an $8.50 handling fee on all orders, no matter what the price is. As far as ride difference, there isn't any. The only real change here was the offset. I did have 15X8 wheels in the back and 15X7 up front with the Hopsters but with the Rallye wheels I went 15X7 all around, basically because of the trim rings. They don't make 15X8 trim rings and you wind up having a nice gap if you use the 15X7 trim rings on the 15X8 wheels. I kept the same tire size as I had before, 255/60/15 in the rear and 215/65/15 in the front. I wanted to go with 225/60/15 in the front but BFG's don't offer that size in the raised white letters.
