I'll throw in my 2 cents having read this entire thread before attempting. If you read the whole thing, you'll have no problem with any of the gotchas. I only have 2 pieces of advice.
Rotor screws... tried impact driver with a 3lb sledge for about 10 hits on each screw after soaking in WD40 for about 10 minutes. Not a single screw budged. Then I broke out the drill and all were out in less than a minute each. You're not going to re-use these things, so if it takes more than about 10 seconds with an impact driver, you're wasting more time vice just drilling them. TIP: the screws themselves are pretty soft... USE A SHARP BIT and don't pull the trigger on the drill all the way... about 1/3 speed or slower will eat that screw up. When I got the rotors off, there was enough shaft of the screw sticking out that I could grab it and unscrew the rest of the way by hand... all but 1. 30 seconds with an easy-out and it was toast. TIP: JUST DRILL THEM... USE A SHARP BIT AND THEY'RE THROUGH IN SECONDS.
7mm HEX for caliper pins... I had 6 different and various sets of hex/allen stuff... not a single one had a 7mm. All went up to 6mm, and then either straight to 10mm, or just went straight to 8mm. Totally random discovery on my part. TIP: BEFORE STARTING, MAKE SURE YOU ACTUALLY HAVE A 7mm HEX/ALLEN.
After 20 miles of mixed hwy/city, the initial bite is a bit less than factory, and the modulation is much more controllable... overall they "softer" but not in a bad way. This car is a 100% commuter vehicle and I have no complaints with the new brakes. I'll be back in 500 miles to report if anything changes.
