I would suggest you do some more reading and searching. The answers to your size and offset questions can be found buy reading the DSMTuners Suspension FAQ as well as these threads:
I would also suggest taking a look at Hankook Ventus Rs2 Z212 that are available in both 245/45 and 245/40 sizes. They have the same treadwear, and similar (some would argue better) grip for the money (both Hankooks are cheaper than both sizes of RT-615s you mentioned). Plan on getting wheels with an offset of ~35mm (as explained if you read some of the threads posted above)
I currently run 245/40 17 tires on 17x8 wheels with +38mm offset.
I would stay away from 255/40 tires unless you plan on rolling your fenders and buying a wider wheel (17x9, ~ +25mm offset), or you are very good friends with whoever it is that will end up trying to mount 255/40 RT-615s or your planned 17x8 wheels.
255/40/17 requires 17x9-35 and some decently stiff and high (1" drop max) suspension to keep the fronts from rubbing. If it's for a daily driver I would not recommend it just based on the dirt and debris that these will throw down the side of your car. Check here for more info:
Also, if your car is a "drag" car the RT 615 are NOT the tires you want. The tires have some of the stiffest sidewall meant for cornering not straight line

I'm biased, but Kuhmo MXs SUCK ASS. I have so many horror stories with that tire, it's not even funny.
Honestly, if your car is going to be making the power you say it is and you plan on drag racing, why not just get some Nitto drag tires like the NT 555-R?
They are DOT street legal

I cant find the Nitto 555R's in the sizes discused above.
if you want a drag grip tire..don't get the 555r..they are the worst of the drag radial series. next is the bfg drag radials...the top of the line would be the mickey tompson et streets. best drag radial imo...and they grip!
I looked at BFG, Mickey T's and Hoosiers... none of them have sizes that fit my application
I think I am going to stick with the 615's untill I get stock brakes up front again so I can run a smaller wheel with slicks... Right now I have the 13" Baer Track kit so I have to keep a 17" rim.

We have Kumho MX on my GSX in 235/45/17 on a 17X8 -35 wheel and they are great.
I have been on them for a couple of years now. We also have them on our WRX. My personal experience and that of posters on the autox list is that it is a great tire, especially for the price. My only caviat would be that they go away when it is cold and wet.
And unlmtdndeavor, my pointer hovered over the negative rep point button for that one. There are good reasons why some people would want to use smaller tires, such as torque gains for autocrossing, but for street cars the narrow sidewall and wheelgap would be unacceptable. What brand of 255 width tires do you know that specify a wheel as narrow as 8 inches?

The statement I made was a generalization of what size WILL fit...not what was ideal. I drive a street car and run a narrower sidewall than stock (17x9 255/40/17), I do not feel as if that is unacceptable. That goes along with my feelings that an 18" wheel are unacceptable, so to each his own.
But I will make the correction that a 255 is not ideal on a 8" rim. For a second I forgot this was in the handling section, I just generalized as I have 255/50/16 DR's on 16x7.5" and that is well within manufacturer's spec. Actually, I could go with those tires on even a 16x7. Sorry if my post was too generalized.
I run 235/40/18s on mine. 225/40 is a small sidewall, thats insane that somebody would try to run a 225/35/18. Personally for city driving I would suggest a 225/45/18 if your not going 235s...See the pictures I post, and see how small the tire is at 235/40/18

You said 225-35-18, not 255-35-18. A 255-50 will fit a 7.5" wheel a hell of a lot better than a 255-35 fits an 8" wheel. With the 50, the sidewall(5") is much taller and can easily compress to fit the smaller wheel without compromising the footprint of the tire. But rollover becomes an issue which compromises handling. Trying to compress a 255-35 onto an 8" wheel causes the tread of the tire to crown because there isnt enough sidewall(3.5") there to compensate. When the tread crowns, you could effectively loose up to 50% of your footprint without running them severely underinflated.
I agree with previous statements, 225 or 235-40-18. I personally run 235-40-18 on my 1g that I got from someone that had them on a 2g. This is on an 8" wheel and they fit perfect and look good doing it.
When I upgraded from 225/45/17 to 245/40/17 the car felt more planted in the turns, it made a huge difference. I would go with a 235/40/18 or 245/35/18, 225s is just not enough tire for DSM, they are too much car for such narrow tires.

225/40/18's here as well on an 8" rim, this seems to be the most common size for 2g's but I'll probably look at 235/40/18's next time I need tires as well, which should fit without too much hassle. Some brands 225's end up being slightly wider then others. With my current 8", 40mm offset rims I had to roll the inner lip on the rear fenders to prevent rubbing.
2. My wheel size is:
Diameter: _18__
Width: _ 8_
Offset: _+38_
3. My current or future suspension height will be lowered
b) One to 1.5 inches
4. If suspension is lowered,
a) Rear camber will be adjusted to less than 1° negative.
b) Rear camber will be adjusted to within 1° to 1.5° negative.
c) Rear camber will be more than 1.5° negative.
5. Rear fender flange rolling:
b) I will not roll the fenders.
6. My driving style is:
b) Street only, but I like to feel secure on twisty roads.
7. I have searched for and read the FAQ's, Tech Articles, and threads on wheel and tire fitment:
b) No, I just want someone to tell me what to do.

And, no, you're tires will not stick out.
