Ah, I just knew I'd catch some heat from Danny for ragging on swing axles.
He can be a bit touchy about that.
I don't drive on the ragged edge like he does. I don't have the patience or inclination to set up my suspension, wheels, and tires to their theoretical best. And I'd guess that more Speedy drivers fall into my camp than into Danny's. So I'd still wager that most real world IRS Speedies will have more useable grip than most swing axle Speedies.
In my case, I got tired of straightening out low hanging tail pipes and replacing sump plate nuts, so I had the car's rear end raised to what is a more practical ride height for me, thus ending any chance of entering the Valhalla of running slightly negative camber. (There's still a manhole cover somewhere in Amador County that's having a good laugh at my expense.)
I also wanted cheap, easily obtained or replaced tires, so I'm not running the optimum size for max grip, either. I am thus content with, shall we say 'middle of the road' adhesion. I know my place in the firmament and drive accordingly.
No matter, though. The wine at the winery, when I finally arrive, tastes just as sweet.
