Similar here - 92 240 SX SE, 225x50x15 Kumhos full tread, 6"x15" rims,
1' neg. camber in front, 1/8" toe out.

That's my assumption also - I'm hearing from others that I need even
more toe out in front since camber is limited, AND to NEVER run less
than 42# front pressure (this from MX-6 owners). My car weighs 2750#,
yours is lighter than mine or MX-6's, so you can probably run less pressure.
I'm using 44# front now.
Try taking tire temps after runs and see how hot the middle of the tire
is getting. If not proportional to the inside and outside, adjust
accordingly
110-->120-->130 = OK,
110-->100-->120 = too low,
110-->140-->130 = too high
:-) 120-->120-->120 = "not in our lifetime"....... :-)

Yep - me too. The Kumhos so much better on cars that are not camber or
rim-challenged.
