You get demonstrably increased grip by using wider wheels, wider tires, and increasing track width.
How much grip is enough is more personal, some guys like to slide some want grip for better safety and lower lap times.
a 993 engine in an early chassis is going to exceed the grip envelope when pushed hard. If you like to slide, spin tires and counter steer stay w/ 6s and whatever tires will fit them. Try driving the stock car hard on a slick road for a little preview.
If not driving hard it makes little difference, the harder you drive the more difference it makes.
from a true narrow body w/ 4x 6Et36 and oe 185/70 x15 tires
+1
rear 7ET 49 +10-16mm spacer for up to a 225/50 x15 tire or use a 7ET 39-33 wheel and no spacer
++1 add 7ET23.3 w/ 205/50 x15 front
+2 add RS/Carrera rear flares
7ET23.3 205/50-55 x15 front and 8ET10.6 225/50 x14 rear
++2 change rear to 9x15ET12-15 & 245/45 x15 tire
+2 alternate use 16s
++2 alternate use 16s
+3 still w/ RS/Carrera rear flare
8x17Et25-30 225/45 & 9 ET12-15 255/40 x17
++3 use 9.5 ET18
+++3 use 245-245/40 x17 & 265/40 or 275/40 x17 on 8 & 9.5
+4
8x18ET25-30 225-245/35-40 & 9.5 ET19 265-275/30-35 x18
when I first put a 3.6 into my '76 Carrera3.0 I had the +2 set up for street and +++3 for track use, I have since settled on ++3 as the best all around setup w/ little to no track use on this car these days
+5
930 fenders
9 & 11 x15, 16,17,18 245-255 front and 285-315 rear
These set ups are fabulous for track use, overkill but great looking for street use
