Diagnose this...I know you can

could be alot of things, but did you by chance knock off a wheel weight on that wheel? Go get the wheel balanced and see if it goes away.

I have a similar problem in one of my daily cars - flutter/vibration at about 65. Tried balancing at 2 different shops, did alignment twice, no avail.
I wonder if one wheel is screwed up? The price of a wheel is not excessive, and the vibration drives me nuts, so I may buy one with a matching tire and start moving it around the 4 corners to see if that works.
Good thread - curious to see comments of others -

im also thinking that either a weight was knocked off, or not torqued correctly.

btw, any pics of the new mod?

1. Front tires out of balance/out of round/ beginning tread delamination. A good tire tech should be able to spot this. Once in a while you just get a bad tire.
2. Front suspension worn bushings, struts, etc.
3. Bad front wheel bearing.

Eliminate the front tires first. You didn't say how many miles on the car or suspension but if the tires are A - OK then it's time to get it up on a rack and have the suspension looked over by someone who really knows these cars.

Front end flutter is not something to ignore. Good luck!

Best thing (and possibly the cheapest, compared to suspension work) to try first is replacing your tires. I had a brand new set of Kumhos I could never get balanced right. The day I replaced them, I thought I had bought a brand new boxster the ride was so smooth... and the tires I replaced the kumho's with were cheaper tires too! (sumitomos).

Im gonna check to see if a weight was knocked off then possibly take it to have them put on again so i know they are sitting right. the car hs 26,800 miles on it for those who asked. My fron tiresare more worn than my rear ones but they are worn on the insides more due to tire pressure that I fixed a long time ago. I have changed my steering wheel and airbag a while back but im sure it was mounted on correctly ( although it seems a little off 12 o clock). Its not wheel bearing cuz a porsche tech looked at it, and its not suspension. I was told last time it may be due to the characteristics of my tires.

as soon as my digital camera works again you will see some nice pics I promise

I developed this problem recently. I had the tires rebalanced and found out my passenger front wheel is out of round. I'll look for a replacement front set.
