How about the Nitto NT05 for the rear? They are stickier, cheaper, and with the tread pattern, depending how much camber you run you can swap the tires from left to right so they last longer than the michelins will.
Or if you are looking for something cheap for the street, try the hankook ventus evo. They get alot of great reviews, even from car and driver magazine and from many here on the forums.
Also why 285 in the rear if the wheel is only a 9.5? I have run 255 front and 285 rear on my 19's and my car feels SOOOOOOOOOOOO much better handling wise running 255 front and 275 rear. not as squirly and more stable especially on the street. Also less chance of rubbing with other people in the car.
I have 245/40's up front. Ideally, I want to maintain the stock rolling diameter for proper speedo reading. I don't notice a real change from running a 275/35. Also, having tires with too large a difference in rolling diameters screws with the DSC and I assume the DSC would be a lot more invasive with 255/40 and 275/35.

I could go with PS3's as they are available in 285/35. I'm just asking questions, my current PS2's are still new and handle great. Just took them to the track today as a matter of fact

Why would 275 make dac kick on more? A 275 square setup is one of the most popular track setups out there, if there were issues with dsc, I don't think it would be so popular

apologies if this is a redundant post...

I just purchased my '02 6MT and the previous owner had installed BBS CH rims and put 235 35 R19 in the front and 275 30 R19 in the rear. From what I've read in this thread, I should be running 235 45 R19 in the front?

He had just installed the rear when I bought the car...the fronts have maybe 2k-3k more before needing to be replaced. Thoughts? TIA

No you want 245/35 front

Because the 275/35 has a smaller OD than his front tires, and a 285/35 would be larger (and thus closer to the fronts).

Having a smaller OD in the rear makes the rear tires rotate slightly faster than the fronts, which DSC interprets as slight wheelspin. As such, you're already that much closer to the "intervention threshold".

With the same size at all 4 corners all rotational speeds are the same, so the absolute OD is basically not a factor.

Ok you're getting a little confused here, You don't run a square 275/35 on the street that's just overkill and the car will tramline like a mofo, unless you really want to.

I would run square 275's on the track though but I'd have a square set of track wheels to accomodate the 275's. My street setup is a staggered set 8.5/9.5.

Now because PS2 don't come in a 285/18 I'd have to upsize to 295's which is exactly the stock rolling diameter but can I get a 295 on a 9.5 wheel with a 28 offset?

I'm looking at some Alufelgen SF-71's in Sport Gunmetal and they only come in 19x8.5 ET35 Fronts and 19x9.5 ET35 Rears. Would those fit my 245/35R19 Fronts and 275/30R19 Rears without needing a spacer?

I'm pretty sure that the fronts are good, but I don't know if the best offset for the rear is 19x9.5 ET20 or ET35.

Are you running stock suspension or with camber plates/arms? 285 in the rear may be too much even with rear camber arms. I had to use -3.5 camber in the rear to fit 285/35/18 NT05.
