Things where awesome you guys had the best price out of anyone but you should update your site as these brakes fit a lot more models than you list!!

Extremely fast shipping - shipped the next business day and I was notified via email about everything. Also, VERY good pricing on the products AND shipping. Thanks!

Great Customer Service, shipping and billing address was different. They called me right away to verify this was no fraud. I will order from them again in the future.
