I have heard of people moving the stock 1.75" rear outer rim to the front making an 8.5" wheel. You have to be careful on the 4.75" very deep outer rim to be used on the rear. That picture looks like the fender lip is probably going to have to be rolled to allow these wheels to fit. It might require the front fender lip to be rolled as well. It might be better to use either a 3.75 or 4.25" outer rim and if needed a small spacer to move the wheel out vs having a wheel so wide that if it does not fit you are left doing body modifications. First picture is a narrow body 964 (meaning no turbo trailing arms) and wheel is 3.75". Second picture is GT2 wheel I built that originally thought 4.75" but it would not fit and had to drop back to a 4.25" to make it work. We did not know for sure until we built a test wheel and verfied fit. jdorociak@gmail.com

I don't know how you guys are running MPS2's in 295 on anything wider than a 10" wheel.
I am running the same tire and I am at my comfort limits both inside and out. I have just .350" clearance to the trailing arm and it has rubbed occasionally on hard cornering. My fenders are factory rolled and I have .250 clearance on the outside. My car is lowered to ROW spec and if I went any lower it would rub in the upper wheel well under hard cornering burning the paint even with some negative camber.
IMO it is better to lower the car and have less rubber than leaving the car high and trying to cram more rubber underneath.
If you want a wider wheel and tire your only true choice is to do the narrow trailing arm conversion and run 11's and 305's. It is an expensive proposition and hardly worth the $$ for the gain unless you need every last bit for the track. The 295's look awfully meaty not sure how much wider a 305 would look or grip. Yes the 10.5" option is possible but what tire would you use a 295 would rub for sure. So it would have to be a 285 with more rounded sidewall.
Another option if you want more grip, go with a larger tail. More down force would do more for you than 10mm's of rubber.
Anthony, what size 295 MPS2's are running? The 285/30 18 MPS2's I have just barely fit, and I don't really like the look at all. If I lowered the car I know it would rub.

Since when did they start making MPS2's in 285. I went with 295 because they didn't make a 285. I have the 295/30/18
I ordered then on June 1st. I got 225/40ZR-18 Michelin Pilot Sport PS2 N3's for the front on 285/30ZR-18's for the back.
Your right, I just checked their web site and they added quite a number of different sizes. That is very good news. Now they have a 265-275-285 and 295 that can be fitted to our cars.
Thanks for the info.
If any of you guys are interested.... I have a set of NB trailing arms,with axles w/CVs and hub carriers for someone who wants to go to 12 inch wheels.

Got to remember few things while doing all this.
You probably can squeeze a 10.5 with 295 but aesthetically it won't like right.The wheel/tire would be sticking out if you looked at it from the front and from the rear.
Several years ago i went with Kinesis wheels 11 with 285 and the combo just didn't look right.I had them change it to 10.5 and it still didn't look right with 285tire.I finally settled for 10" with 285/30/18. If memory serves me right the offset is in low 50's (51/52)
If i have to do it again,i would still go with 10" wheel but with 295/30 tire as it would just fill the fenders perfect with out giving the car "the camaro look" I am lowered on Bilsteins/H&R springs.
Bottom line is.......I would rather have a 10" wheel with 295 tire than a 10.5" wheel with 285 tire.
Hope this helps.
I have just picked up a new set of Work M1s, the rear wheels are fine as 53mm. But the front ones are 30mm offset, it rubs like crazy. So 45mm is going to solve the rubbing?
Going to 45 ET 8" should fit just fine if you can get there. Stock is 52 ET 8 Speedline 3.6 Turbo wheel, and the Alessio Speedline wheels came standard as 45 ET 8" and they fit fine. These two style Speedline wheels used the exact same size inner and outer rims the difference was the height of the back mounting pad in relationship to the flat surface where the nuts are, so it is not always just a larger or smaller rim size that changes the equation but the pad height as well. Some other Speedline sets say like the 964 RSR came in two additional front wheels sizes and ET's that also fit. 64 ET 9" (964 RSR Speedline front wheel) or I believe Cobalt has a set of 57 ET 9,5" 964 RSR front wheels, and the 993 CUP cars actually ran 53 ET 8,5" (same stock size outer rim, higher pad height than other models and a 1/2" deeper inner rim) Good luck!
