thanks for the info - the renntech stuff was excellent. as far as I can tell from their website, the boxsters can do DE "as is", but if I go beyond DE then I suspect I'm looking at having to get the extension. the DE school is turn one at carolina motorsports park in SC. Will let you know how it all comes out.
other than the cost, the extension seems pretty straight forward according to the other threads - encouraging!
adam - I'm not heeltoer - but it is something I plan to enjoy refining next week
