staggered wheels

[oasis]

400 hp?

I was thinking my next air-cooled car might pack more of a punch than the 2056 in my 1302, but 400 ponies?

Anyway, I get most of what you are saying. My 1302 had 16x6½ wheels on it. The fronts had 195/50-16 tires; the rears had 205/55-16. The only reason I changed the front tires was because I had slight fender fouling and I wanted to keep them stock.

I noticed some stock Porsche's had wheel combinations of 9- and 10-inches wide, front and rear, respectively. (I don't know the associated tire sizes.) The Porsche was likely pushing more power than I intend -- perhaps even more power per weight than I intend. Intuitively, it seems a 180mm to 250mm ratio (~2.75-inch difference) would be an enormous difference -- much greater than the 911 or 996 or whatever raised my attention to staggered wheels.

Let's start with something fairly pedestrian. What is slip angle?

I'm also wondering what starting point of equal-width wheels I should consider, but I will save that for when I get my platform and have more specifics. Let me also ask, though, why do you think the Porsche has staggered wheels?
