Why are there four GT3's testing in the mountains near my house? Each
has the entire "backseat" loaded with electronic gear and the front seat
has a laptop stand. Each has ceramic brakes, some with 4 piston and
some have 6 piston calipers. They all have Michigan plates (look like
manufacturer plates), who would be testing these cars, not Porsche?
I have pictures of brakes, the electronics in the back and the cars.

 

Sounds as if someone was out doing their 'homework/research' as I can't imagine Porsche testing their vehicles in MI...?

 

These 4 cars were not in Michigan, but were testing at 10,000 ft. in Colorado. I found it strange why Porsche would not test in Europe,
however the altitude is much lower in the mountains of Europe. Then
I wondered if these could have been cars that another manufacturer
bought to test (i.e. GM, Ford etc), but given the big fours economic
conditions, maybe they are Porsche vehicles. Some cars had "3.8"
on the rear wing, so these may be the newer more potent 3.8 engined
cars due out in October.

 

Great job man..
