I have run HP+ on all my E36's with no issues in CCA intermediate groups and we currently have a set on the ZO6 with no issues. Just got back from Buttonwillow from a 2 day school and the pads certainly held up well. I certainly will look into an upgrade since the husband is starting to get a little fast and needs stronger brakes. All the cars are on the lighter side but that ZO6 is just so damn fast.
