Yes, the AX6 compound (panther plus) is the way to go for everyday street driving mixed with autox and track day events. They do create some dust and noise, but it's not that big a deal. Yes, if you put together a group of contour guys I will give you a good discount. We can order those backing plates from one our suppliers, or you guys can send us some used ones (no damage). Tell me how many guys you think you can get together to do a group buy and I will let you know what I can do. Our pads are all Ceramic based, so they have excellent modulation and are very rotor friendly. Please let me know if you have any other questions or comments.
For the front in AX6, the price is $119 and $107 for the rear. If you order two sets I will take off 10% from the total.
