Agreed. I put mine on two weekends ago. I haven't had the time to do a proper alignment, but just driving back from my buddy's house to install them, they felt great. I'm running 9k/11k springs, and I can say that the ride quality is definitely as good, if not better than stock on the softer settings - except the car doesn't roll as much.
The real test will come once the car is ready to race: I need to fix the ride height (guesstimated it and ended up with the with rear tires tucked under the fender and the nose sky-high ), fix the endlinks (spherical endlinks = PITA), mount the RE-11s, align it, and I'll be ready to go for this season.
Concerning pads: Look into Hawk DTC-30s. I have these on my car, and they are probably as much pad as the car can deal with on street tires. They work brilliantly for autocross, and probably track days, too - haven't been able to do one on them yet. Daily driving will get a little noisy and dusty but you'll get used to it after a while.
I do know from experience, however, that HP+ suck for track days. And that was on a 2700lb 240SX with 300ZX TT brakes. I can only imagine they are worse on an Evo.

I was trying to decipher the tire reviews. But I do notice one thing: the tire pressures at 40+ seam very high.
my car 06 GSR 245/40/17 oem rims, GTworks springs, whiteline rear sb(medium), 2.6/1/8 FT, 1.5/0/rr
Personally I found that the reducing pressures down to 32-25lbs was best handling combination in my car. I used an infrared gage to measure temps across the tire surface and to get the most even temps these pressures seam to be the best.
I also noticed that on warmer days it was absolutely necessary to spray the tires after the second run.
The tires sweet spot seams to be around 140 degrees. More than that and the felt like greese.
So tell me i am out and left field. Because I am always willing to try new things.

"Take care not to contact the parts or tools to the caliper
because the paint of caliper will be scratched. And if there
is brake fluid on the caliper, wipe out quickly.
1. Using a micrometer, measure disc thickness at eight
positions, approximately 45 degrees apart and 10 mm (0.39
inch) in from the outer edge of the disc.
Standard value:
<Front> 32.0 mm (1.26 inch)
<Rear> 22.0 mm (0.87 inch)
Minimum limit:
<Front> 29.8 mm (1.17 inch)
<Rear> 20.4 mm (0.80 inch)
NOTE: Thickness variation (at least 8 positions) should not
be more than 0.015 mm (0.0006 inch). "

Question - if one were running highly worn stock rotors and they measured in at less than the Mitsu minimums - would that be "illegal"?
How about with aftermarket rotors? If they are within Mitsu specs when new they are legal. If they get worn to under Mitsu specs do they then become illegal?

No doubt
If you are looking for dual duty track pads, then definately consider the Ferodo DS2500s. As anyone who has used these pads will say, by far the best street, auto-x and track day pads for the EVO. I've had other street pads literally crumble on the track. It has a higher thermal capacity than the Hawk HPS and HP+ and can easily last multiple track days.
PS: If you're interested I'll probably be selling some front and rear Ferodo DS 2500s and RotorPro slotted rotors soon. Definately for a cheaper price than any vendors ... anyone interested PM me ...

Properly set up, these were absolutely the best purchase I've made for the Evo. I ran two events this weekend and I'm killing a lot of the STU competition and even eeking out times a few tenths faster than some really top notch drivers that I wouldn't have dreamed of competing with last year. A good set of tires and some quality instruction on Saturday helped as well. I'm really looking forward to this season.
