oooooooooooo I’m jealous; had a couple 914’s, never a 914-6. You’re right; damned uncomfortable......but SO much fun to drive. Corner like they’re on rails.
Let me know if you wanna part with it. :)
I am currently using US 528 wheels, but have the original Euro sized factory rims for the M5 - 205 60 390.
The car should sit only about 3” above the ground. Even though that front air dam is virtually irreplaceable, I want the car to run lower the way it is supposed to. It makes a big difference at 180 mph (on the track, of course).
I can always keep the 528 wheels on or get newer model BMW wheels and go with 205 55 16, 215 55 16, or 225 55 16s.
