Seems most of the wheels and tires are 15  x 5 or 5.5 .

In general how big can you get away with wheel and tire size on a speedster without having to flare the wheel wells, etc...?  

I have always simply left the standard wheels and worked from there. 
But I am mapping out ideas for a  mildly modified Outlaw.

As always, I appreciate you guys.

Lot of discussion in the past about this. To save you some time: Swing axle, drum brakes up to 5.5" wheel,195 tire. Swing axle disc brakes up to 5" wheel 190 tire. IRS drum brakes up to 5" wheel 185 tire. IRS disc brakes 4.5 wheel 185 tire. Based on steel wheels standard VW/Porsche offset.

I have IRS with disc brakes and I'm running 5.5" Mahle baby burners with 185 tires. Had to shave the rotor face and grind the inner fender lip to fit.

Actually, you can get a fairly wide tire on the rear if you simply have a rim widened sending the depth towards the center of the car.  

You might have to experiment but Carlos essentially you have an IM and Henry can tell you exactly what he has done for his other builds.  A few verification and the rear wheels can have different shoes.

205/60R 15 I remember were my rear tires on my 2004 IM.

If you are ok with steel wheels.  Late model 914s came with a steel sport wheel that was 5.5x15" ET40 (VW had similiar but offset was only ET34).  They are simple/inexpensive to reset the mounting surface to get more off set.  Looks like you could get at least 1/2 inch.  If you wanted to increase width at same time - suspect 6" would work.  They can be painted or powder coated for different look (as below).  Stock they were dull grey - but a chrome powdercoat would add bling.

Here's a set on ebay - but same cost as the new 5" offset CIP1 Fuchs!

Looking at Fuch type wheels, 5 lug. The 914 styles are more flat faced than I would like
