feels like more oversteer lately

[Sboxin]

Well...you are doing all the right things so far --- but, if you have even a slight bit of rear toe out the rear end will come around on you (I think this is right - someone speak up here) --if you feel the rear left is lifting on hard turns then I would look at spring and shock replacement -- and even sway bars can weaken over time - and you have 89K on the car.

IIWM -- I would take it to a Porsche suspension specialist - if you have one in your area - I found one here in Phoenix after talking to a lot of people and finally a friend found this guy in a one man shop that mostly works on Fcars

Take care,

After checking all the logical things (shocks,alignment, etc) consider that you might just be more comfortable with the car and are driving more agressively. I own a kart track and over and over we hear drivers saying that the second kart they drove slid around more than the first kart, and almost without fail it's because they were driving the second kart faster which causes them to slide around more in turns.

thanks. I'm actually driving it less aggressive now as compared to 1 year ago. I only feel this sensation during hard cornering.
A thought is that with new tires only on the back, the car maybe riding on the inside edge of the (new) tires due to negative camber and making the rear end more twitchy??..
i think its about time to replace shocks and the rubber pieces on the sway bar.
I enjoy driving my Boxster (non-s 5 speed) for commuting and weekend drive on mountain roads, (slightly faster than most, but nowhere near those that go to track), what's the expected life of shock absorbers?

Start with an alignment. Then get someone knowledgeable to look at suspension bushings, front motor mount and finally shocks. Also look at sway bar end links. These are kind of a weak part of the Boxster suspension and can easliy wear out but the wear is not visible.

I think I'll start by looking at the rear sway bar/droplink setup.
the oversteer came on suddenly.. I think. so the drop link play may induce the back to roll much more and enable the back end to ever so slightly induce oversteer - I think.

We remove a rear link when the car is understeering (pushing) removing it decreases the amount of rear grip.

Look for a FRONT drop link broken. These break a LOT more frequently than the rears (they turn with the upright)

In 10 min over the phone I can walk you through checking the rear toe on your car. It requires 4 jackstands and string.. and a tape measure. I'd only check this if you KNOW you have hit some major pot holes or bumped a curb. The only time I see rear toe adjustment "out" on our cars = when somebody is really bouncing the cars off the berms at the track.. and I have a solution for those people also

I'm going to thoroughly inspect the drop links per your first suggestion.
I may take you up on the second... but it's been my experience (haven't really tinker with cars for 25 years) that if the toe in/out is out of spec, i would notice wavy wear pattern on the tire. rear set of rubbers were replaced couple of thousand miles ago and the problem was first "felt" about the same time. both very recent.
