you'll rub
I have seen the older A5 hoosiers on the rear of the car in that size with 50mm offset wheels but those rubbed even there.
Given the choice right now I would go with V710's over the hoosiers if they are an option in the size you need until I hear how the hoosier lifespan is on the A6's.
I would bump down to 15"/16"X8 and go with a 225/50 in either of those sizes. Or maybe the 215/40 V710 if you think you will still have trouble fitting a 225 under there.
I have run 235/40/17 toyo RA1's on the MSP with minimal rubbing with a 5mm spacer on the front on the stock racing hart wheels.

So David LaRose just placed second in his MSP at the Solo 2 National Tour in Devens, Mass. He's listed as running Hoosiers. I would assume they are 225/45x17 but don't know for sure. Anyone ask him how they fit? Is he on this board??
The A6 profile has a more rounded shoulder than last year's AS05s do, but I don't know if this makes any difference in fit. I heard at Atwater that Paul Brown (93 MR2) was pleased with the wear of the new A6 Hoosiers, and that's on concrete that resembles 220 grit sandpaper. So they are expected to be better wearing than the AS05s, but that isn't hard to do.
If anyone has actually fit a set of A6s to their MSP, please speak up!

You are half right.
He is still running the A5's he was running 225/45/17 in the rear and 245/40/17 in the front. They "fit" but they rub a good bit. Also he was kicking ass in the dry on sunday I think he beat everybody else in class by a second in the dry it was just that the saturday wet times held him back.
I saw him peeling strips of rubber off the tires where they had rubbed off.
He uses a 50 offset rim Kazera KZ-V IIRC. Not sure if there is a better offset to try to run those tires or not.
The A6's have not come out with the 245/40/17 size yet.
I just put a set of 225/45/17 Potenza RA07s on a 17X7 45 offset wheel and only the rear rubbed on the fender. I'm rolling the fenders tomorrow so they fit. THe fronts fit perfect, no rub at all even at full turn in. I have the Tokiko Illumina struts on my MSP with stock springs. The new rear struts make the car sit lower than stock. If I had the stock struts on I think they wouldn't rub at all.
Problem with this offset, it takes you out of stock class. Are you running D stock or DSP? WHat class did David LaRose compete in?
Moxnix, how far did those 235s buldge out from the stock rim? I would think they'ld rub against the front inside wheel well and the rear strut. Those are the only close points on my car. Those tires had to of looked like they were going to pop right of those 7" rims!

In stock class you can change the offset of your wheels up to 1/4 inch (a little over 6mm) the MSP has a stock offset of 55mm and the 50mm wheels are within the range. David LaRose runs in DS.
The first weekend I ran them on stock rims with no spacer I rubbed a bit.
See this post about my rubbing

They are not nearly as bad as I orginally thought they would be.
Wow, those don't look too bad on the stock rims. I thought the sidewalls would of been way out. THose tires look more narrow than the 225/45s I just put on my aftermarket 17X7s. Could you measure the width of those? I'd like to compare it to the Potenza width. I would rather run a lower profile but wider than a 215. No one makes a 225/40/17. If a 235/40 would work I would run it all the time.
The tires are tucked away since I am running the miata this year but reading some of my other posts.

you can find the section width. Actual width is going to vary based on who makes the tire so not sure how much that helps.
If you go to tirerack look up the section width on the tires you have and what size rim that was measured on. Add about .2 inches to the section width per 1/2 inch in rim width difference. or subtract the same amount from the wider one.
I.E. 225/45/17 RE040 8.9" on 7.5" rim. since the RA1 was measured on a 8.5" rim you would subtract .4 from the RA1 so it would be 9.2" section width. while the RE040 has a section width of 8.9".

Looking at the Toyo 235/40 section width and rim gives 9.6" on 8.5" rim; so it should be about 9.0" on 7.0" rim with a 24.4" dia. These rub a bit, as your pics show.
So looking at A6s from Hoosier it looks like the 225/40 is 9.4" on 8.0" rim; so it should be about 9.0" on 7.0" rim with a 23.9" dia. The shorter dia should help drop the wide part of the tire lower down the strut where there's more room and it lowers the car 0.25" due to the shorter dia. Better for center of gravity and more revs coming out of corners so better boost.
Key question: when are the A6 225/40 x 17 due to come out???? This looks like the tire to have that will fit without rubbing on the MSP. First one to try a set, please post results. Thanks.

Macs MSP: I'm a little embarrassed to say this, but I don't know how much the A6s cost me. I guess they went for list price, which is $219 each, plus shipping from Indiana to my place. List prices are available at www.hoosiertire.com/rrtire.htm and click the "2006 Price List" link to download a pdf.
I will update info as I find out more.

I'm curious as to why one would want to run such a large rim and tire combo unless it's a very powerful car (and perhaps it is, I don't know what you drive).
I shoehorned a set of 245/50/15 Hoosiers on a 15x7 rim (if you want the tires, let me know, I need to get rid of them and they're brand new!), and the sidewalls were BADLY pinched. I couldn't imagine trying to run the same width tire (or at least close) with a shorter profile on the same width rim! You might get a slightly bigger contact patch than a 225, but I'm not sure it's worth the additional expense and difficulty in mounting the tire.
I run a 225/45/15 Hoosier on my track car (OEM size is 205/50/16), and a friend runs a very similar setup with a 245/45/16 Toyo (on a 16x7 rim). To our surprise the 245 Toyo is just a hair wider than the 225 Hoosier on the size width rim! Although his sidewall looks more pinched than mine. Anyway, my point is that my 225/45 looks pinched on a 7", the 245/50 looks worse, I couldn't imagine a 245/40. That's almost seems downright impossible on a Hoosier (but probably possible with a Toyo).
I'm getting some 15x8s soon, so I'm curious the increase in section width and effective tread width. Hoosier says there's roughly a 0.2" increase in section width for each 1/2" added to rim width, so I should gain 0.4"!

people who run old civics in Stock class run 225/50/13s on 5" rims...and people are trying to tell me a 245/40/18 won't fit on an 18x7. pshht.
Let me know, they're collecting dust right now. I might try to fit them, but I don't think I want to run a tire with that large of an OD. 
An LSD, clutch, and flywheel will make it feel like a new car. I know exactly how you feel.

well, neither of my cars could even remotely be called "powerful," what with 238 crank hp between them.
my 18x7 example was made b/c that's the stock size that will apparently come on the car i was referring to (the MS3). Stock class requires stock-size wheels; i've complained enough in other threads about the OEMs' relentless drive towards bigger wheels on "performance" cars.
Holy crap, that car come with 18s standard? ugh.
My Prelude puts down 204 WHP with a fairly inefficient transmission, so I'm guessing about 240-ish crank HP (a stock 195 HP Prelude will only put down about 160 HP or so). Anyway, even though my car is not "powerful" I couldn't imagine running 18s on it. No way! They're all way too large, not to metion the weight.
