[Shotimes] yet another tire/rim question

Yeah, yeah, yeah, that's what I meant about apples and oranges.  ; )

If 215 size tires fit reasonably well on a 6" wide rim (stock setup on a 92), and now I've switched to 235 on a 7.5" wide rim, I've maintained a fairly close ratio (rim delta: 1.5 in x 25.4mm/in = 38.1mm;  tire delta: 215 + 38.1 = 243.1).  So I am actually narrower in that respect.  The tire sidewalls are very much vertical and square in my setup.  Given a capable driver at the wheel, I would expect this wheel/tire package (about same weight as stock) would yield better lap times than the stock tire/wheel.  I might be off a bit given the recent stories about effects of rotational mass robbing HP, but I would still expect the handling characteristics to be better and thus allow the car to get around the circuit more quickly.  

As for the Porsche, that's fine.

Shotimes ate your post too.
