2003 Boxster doesn't corner as good as 2011 Golf TDI?

[The Radium King]

are those front tire pressures hot or cold? if hot then you should be around 36 psi front - you might be rolling onto your sidewalks - chalk your tires and see what happens.

if cold then perhaps too hard; oem is 29 for the front I think - check front tire wear and see if you are wearing the middle of the tires more than this sides.

Bottom line: there's something wrong with your Boxster. My wife has a BMW 325 xi, and cornering in my Boxster makes the BMW, which handles really well, feel like a pig in comparison. Of course, the Boxster has new ROW MO30 suspension, but it feels like it's on rails!
