depends how much looks factor into your decision... i run a 255/35/18 re-01s on 18x9.5+38 rpf1s (weigh 18.3 lbs each) so I get nice low profile and wide stance, no fender rolling needed (just front spacers), coilovers not needed, and looks and stance is killer. Performance (weight/rotating mass) and cost wise 17's are probably better, but personally I would still go with 9 or 9.5 width even though its slightly more weight just to be able to run wide tires- to each his own I guess

This thread isn't about aesthetics. Even if it were, if one's mindset appreciates the concept of form following function, the aesthetic component is diminished, as well.

You are correct, for the OP there would be no other point in going with 18" other than running lower profile rubber for cornering benfits. I should have stated that more clearly. For me, looks and cost were a factor as well as performance, so my situation was different. Although I personally run 18x9.5 I suggested 17x9 or 17x9.5 for the op.

yep, same here...I'm running the Baer Eradispeed rotors all around! In addition I'm running a Devo Tuning aluminum, 2pc driveshaft... more rotational weight loss there!

This spring/summer a 10 lb ACT prolite flywheel is going in my EVO

What size tire are the 17x9" and 17x9.5" proponents recommending? how big of a tire can one go on a 17x9.5" with minimal rolling?

The real reason to go with larger wheel, is to fit larger brakes. You can't fit 355mm rotors inside 17s, so if you have any intention of upgrading the brakes with larger rotors in the future, 18s are a must. Which is why I'm running 18X9.5s now.

17x9 or 17x9.5. This wheel size is really perfect for the Evo. You can run a very aggressive tire and it won't cost nearly as much as a set of tires for a 18inch wheel. 255/40 17 is the perfect size for the 17x9 wheel, which is what i personally run. Minimal fender rolling.

Regarding brakes, I would only upgrade the brakes if you prefer a BBK's looks. I don't feel like the stock Brembo calipers need to be upgraded, as long as you are using the correct pads/rotors. No doubt, a BBK will work better because it has more surface area and more clamping force(depending on the caliper), but i don't feel it warrants replacing the stock Brembos. IMHO.

What about 18x9.5 w/ 285/30/18. Less fitment issues than a 275/40/17... Depending on wheel offset, you'd only have to roll the rear.

Fixed poll to show stock size, which is what I recommend for DD.

+1

This.

Also, less rotational weight of an 18" wheel and the accompanying rubber.

Please help, as stated above, 17x9 is a good choice. if so, what offset is best? without the use of spacer. I know ppl do spacer in the front, but that will led to the center bore not there to help hold the rim bore.

offset will be rim specific, as the spoke design will impact whether it clears the caliipers or not.

The 17x9 +35 fno1r-c's fit w/o spacers
The 17x9 +35 rpf1's do not clear calipers

... check with the manufacturer, likely need to be in the +35 or +30 or less, depending again on spoke design.
