Thanks Sandeep.
The grey car is from Franc (ww.carsche.nl) and is a '74 model. We know each other some 20 years I guess...
He has taken lightness very far as it has carbon bumpers and self made aluminium bumper brackets. The Wiechers cage is also aluminium.
Engine is a 2056cc type 4 and has some of my old parts in there (JE pistons, Webcam 86, type 1 followers). BAS exhaust and at the moment 40 IDF's. He plans to upgrade to EFI with a DTA E48 ecu soon
Tires are Toyo race-intermediate slicks IIRC. Very cool!
Wheels are BBS 16" , so not that big really ;-)
