Yes, the brakes felt good on the 1st lap. I'm sure they're just some over the counter pads from the local parts store.

That's good to hear about the hawk pads, I'll have to check those out before ordering the carbotechs. Does the dust from those come off okay, or is it corrosive?

When I purchased my car I was told the DRM spring had already been installed, so should be good there.

BTW, what rotors are you running? I noticed mine have developed some grooves. Not sure if I can get away with having them turned, or if I'll need a new set. It'd be cool to get some fancy rotors with aluminum hats, but I don't want a drilled rotor for fear of cracking, and don't want to pay the price . Wondering if my best bet would just be a new set of Napa premiums.

Cooling ducts look good. That's scary about the hubs, had no idea they only lasted a few events, I'll start checking mine! Are you running r-comps or street tires?

Carbotechs are the only pads I've seen that say they are non-corrosive. I asked a Hawk rep at the track if theirs were, and he didn't seem to really know, or didn't want to say. The hp pluses dusted really bad, black streaks down the side of the car, not to mention the wheels turned black. I've never seen any evidence of corrision and I was looking close. I always washed it off soon with no trouble.

The HT-10 pad doesn't really dust at all. I use stock style rotors with no holes. Napa rotors were recommended to me from a local shop that sets cars up for this. As you mentioned, they crack from the holes. The hp plus pad were killing the rotors, not from grooves though, vibration. They never lasted long enough to crack. With the ht 10 it looks like they are going to last long enough to crack, starting to show heat stress cracks now. I put street pads and discs back on when the events are over. The ht-10 don't brake good until they're up to temp, so they are not street friendly.

I can't really say on turning the rotors, could make a good track set, or backup set. I turned one set and they lasted one day before vibrating, but that was on the hp plus pads, so it wasn't a very good test.

If you want to fabricate ducting, here's another place.
