Yep. Well, 10hp difference is next to nothing then the Spyder is 25kg lighter, so call that even. GT4 has more sophisticated, adjustable suspension - the conditions will dictate when that comes to the fore on any particular set-up of it. GT4 has more aero downforce. At what speed does that provide a downforce advantage as opposed to a drag deficit.
It says 7 seconds difference around the Nurburgring. All things considered, how much of that is down to the tyres.
For me the conclusion is, you can't go wrong with either and you need to take them to the track to split them and if you're more inclined towards track performance why not pick the GT4. If you're more inclined to get your kicks on the road pick either. If you want and open top pick the Spyder.
And it goes without saying, if you want a Spyder pick the Spyder. If you want a Boxster (i.e. standard body shape and power hood) pick the Boxster!
