I have run them on the street all day in city and highway driving and on the track at Daytona and Sebring. I was pleasantly surprised. They have a very linear increase in grip instead of having them get grippier as they get hotter like the Hawk Blues. The Blues are more difficult to use hard without locking up a wheel. The PF's are very gradual regardless of the temperature. If you push harder, they stop better.

Lesser pads like the Hawk HP+ would be vaporized in just a couple of laps on the same track.

A common upgrade down here is to use the 1800 front bracket with 1800 rotors but retain the 1600 caliper.

On my journey to where I am now this was a great setup with Carbotek Xp10 front and XP8 rear.

They were a bit dusty but worked okay on the street and very well on the track but started to get too hot towards the end. If you are doing mountain work (which to me, is more than fast road but not quite track level) I think they would be really good.

Perhaps some ducting as well if required.....ducting improved my pad life considerably.

The OEM 1800 caliper brackets are very reasonably priced from Mazda (here at least).

It will leave some unused area on the 1800 rotor but at least the caliper to master cylinder ratio is retained.

Fresh (race quality) fluid every 3-6 months will be a huge help as well.

Got the NB sport brake booster+MC installed.

Brakes are much better

Should get pads.

Ok I am sort of happy I came accross this thread. Next on my list is brakes. I have a leaking brake booster and/or master cylinder. There is/was fluid leaking out of the brake booster near the master cylinder. I never physically saw a puddle or noticed my brakes were bad, but I also put only around 1K on my car after picking it up last year. It wasn't until this fall when painting the engine bay that I noticed my fluid actually went grey on me. The fluid was freshly changed by the PO, a friend of mine. So age wasn't the culprit. Also it was pretty obvious that there was an issue with the evidence that the brake fluid was leaking out of the booster and below the master cylinder.

Anyways... the brakes worked fine on my drive from the garage to my garage (storage) but they are the next thing I am going to replace. I was thinking new Brake Booster / Master Cylinder and BBk (949 11" Willwood kit) and swapping over to 1.8 Rears. Are people really suggesting to run 1.6 brakes over the 11" kit? I still have to research which master cylinder (OEM/Aftermarket for the larger fronts) and anything else suggested with the swap.

Car will see it all. Street and Track Days (I host them for my buddies shop). Technical and High Speed tracks. Typically 20 - 25 min laps. Running seperate track pads and street pads.

So you want me to copy and paste this into your thread?

Derek, consider the 949 11.75 fronts instead of the 11.0. They use the same calipers but I believe the larger rotors are far cheaper to replace and will have a much greater thermal capacity. I believe I'd heard that the price difference balances out at your very first rotor change and continues to improve dramatically from there.
