What's the negative effect of running a positive scrub radius on a 993? Is it dangerous? Is it harmful to something specific in the steering or suspension?

With PCR, if you engage ABS, it can rip the steering wheel right out of your hands.

Its not a good idea.

Big positive or big negative increases the feedback to the steering wheel, to big in either direction is bad

S/R depends on the wheel width & ET
911s through '89 w/ 7ET23.3 have a S/R of +52.4

for ABS to function safely S/R needs to be zero to negative, 964s w/ 7 ET52 wheels have a S/R of 0

993 was given a little more feel in the steering, it was the sporting thing to do, 993 w/ 7ET52 have S/R -10

I've always wondered how those RWB cars are when driven hard.
