wheelmax.com worked for me....
basically i called to enquire about an offset and the salesman offered to give me a discount if i bought over the phone with him instead of online (obviously he got a commission) so i took my 100 bone discount and bought through him....
oh and i had opted for the toyo proxes4, but they called back the next day and told me they were out. the gave me the option of waiting til they were in stock or i could go with the next higher priced tire for the same as the proxes4's... so i took the Yoko AVS ES100's no complaints so far...
