I did a search but really couldn't find a difinitive answer..... I need to replace the front rotors on #1303. The rotors I have I believe I bought on eBay about 3 years ago, they are basically stock replacements that were drilled & slotted (they were not Powerslots). Anyway, as I am digging into the car to get it ready for the upcoming autocross season I noticed the left front is heavily cracked, from the last track day I ran I suppose. I looked on Tire Rack, but the only thing they list for the GVR4 is Brembo stock replacements. I would like something that is slotted, but not drilled (prone to cracking & not neccessary in autocrossing). What rotors do you guys run? Best place to get them? I will be using Hawk HP+ pads, I've always had great results from them. Let me know, thanks!
