I do not know if there are any off the shelf wheels to meet your needs. 

VTO Performance has some 15 x 7 inch wheels that have a 5 inch offset which corresponds to a +25mm offset on 7 inch rim.. They can be drilled for the 108mm (4.25 inch) bolt pattern. You might be able to use them with a 5mm spacer in the front. I got their 16 inch x 7 inch wheels back when they were Superlite branded wheels so I cannot really say this would work. There might be an issue with having long enough wheel studs length to give the lug nuts enough turns. 

My autocross wheels are just old 15 inch Mustang turbine/hurricane wheels, with Dunlop Direzza Star Spec tires. I have to run 3 mm spacers front and on those for clearance. 

BTW my 16 inch Superlites were drilled for 1/2 inch studs but the 7/16 lug nuts they supplied made every thing work Might want to see if the 15 inchers they have now can be drilled for 7/16 inch studs if you talk to them.

Both front and rear lips are either trimmed or rolled on my car, per Tom Hall's methodology :-)

Correction to my initial response. On the rear I did trim the excess inner well lip back at the top to the spot welds for additional clearance. For the most part that just involved trimming off the amount of extra inner fender well metal to the edge of the stock outer fender lip. A minor adjustment in my view. No fender lip rolling involved.

I personally like 15 inch wheels with 205/50 tires on 7 inch rims. That is the setup I have for my "street tire class" autocross tires. They give a very nice ride in conjunction with my 450 lb. front springs. My regular street wheels are 16 inch wheels with 7 inch rims with 205/45 tires in the front and 215/40 tires on the back. The result is a bit on the harsh ride side. 

The issue with 7 inch rims on the front is to have the correct backspace. You need a backspace of 4.75 inches to get the wheel and tire to fit reasonably well inside or equal to the outer fender line and still have the wheel clear the suspension control arms at full deflection. Given the width of the 205 tire, you will have to trim off about 1/4 inch of the lower edge of the front valence where it curves back a bit toward the wheel opening for clearance at full steering lock. Many people have done that and the trimming is really not noticeable to any significant degree. I did not have to do any other wheel well or fender lip modification. 

While you are not predisposed to 6 inch rims and narrower tires on the front, keep in mind wider front tires result in a noticeably heavier steering effort especially at low speed.

I'm about to buy some new wheels for my Tiger. Because of the lack of 
quality off the shelf wheels for our cars, I'm leaning towards 15" diameter 
Panasports. While kind of "belly button" wheels, they are very well made and 
reasonable cost. 

The usual 6" front/7" rear fitment has limited appeal, primarily because 
of the handling compromises that result. I'd like to run 7' all around with 
equal size tires. 

Anyone have direct experience with the 7's and clearances? My valence is 
near stock, we did do some basic smoothing, prior to the car going to paint. 
How large a tire might fit? (I could see running as small as 195/50-15 at 
all four corners). 

Thanks for any thoughts!
