Name that flare!

[Blackbyrd]

Just got these flares but trying to figure out what they are
As I recently sold a pair of 930 and they were much sharper looking edges


These are very round

Any ideas ?
St rsr 73rs ?

Interesting.

Quarter panels are for a car without torsion bars... Weld-up - likely for a race car converted to coilovers. Notch on pass. side indicates 964 chassis.

Look like Turbo contour to me, but perhaps aftermarket stampings. ST have a bit broader 'flat' area... but width is closer to ST than Turbo.
