Where the lower control arms are attached to the subframe, the bolts pass through the subframe, there are two sets of holes for those bolts which keep the inboard end of the control arms attached to the subframe.

You might find this funny, the rad is made by AKG but actually made in Germany. Hopefully, this will last longer then the unit in our 30v. ; )

Is it thicker? Better or more dense fins? Turbulence generators on the fins?

A question I've been wondering for a while... I saw a pic of a GT2 or GT3, not sure which one but likely a 996 or 997, are the fins of the radiators on either side of the front wheels angled. Meaning are they angled so that the placement of the radiator makes the fins longitudinal like the fins are on the radiator you just posted a pic of?

I think you know that it isn't impossible for one vendor to produce components of multiple levels of quality. I'd hope the unit specced out by Porsche would be of satisfactory quality or longevity. However we do have to wonder if a limited life span is a part of the design.

Its almost twice the size of the standard(2.5-2.7) units and still fits under the intake housing. That's an "S" unit or 3.4 unit in the pic. There is a bigger one for the "X51" optioned 996's, but the intake is taller on those coupe body cars.
The cooling fins I've seen on the rads are vertical, but the level of ducting is significant. They clearly do alot of R&amp;D in the wind tunnel. It seems every bit of air is ducted or controlled in some way on these newer gen cars. The side rads seem fairly robust(BEHR/Valeo that I've seen) and should easily provide 100k+ service intervals, if not more.
