996TT Wheels on Super with Kerscher Fenders?

I am looking to run a set of 996TT 18 inch stock wheels and tires (8 with 50 offset, 11 with 45 offset) on late aluminum arms on a 79 Super. Anybody doing that who can tell me what size fenders to order?

Thanks

Late alu arms ( widest combo ) with 11cm inner and outer widen fenders from Kerscher with 11x18 et 45 996 tt, one side 10mm spacer, the other 43mm spacer. Had an accident B4 on the side with more spacer. Front with 22mm spacers with 9x18 et 50 996 tt wheels with 6mm fenders. The car looks fat but nice like a wide body 911 from the rear! Front a little too wide, I would go 4cm with 8x18.
993 c2 brakes all round.

If nobody knows, try calculator, like i did.

Stock wheels vs 9,5" wheels



Empi 8-spoke vs 9,5" wheels.

Kerscher has stock, 2cm, 4cm, 6cm, 7cm and 11cm for the rear.
Stock, 2cm, 4cm and 6cm for stock look, 4,7 and 11cm are flared fenders.

Front, 2, 4 and 6cm

That does not tell me anything other than how much wider the wheels are than the stock ones I haven't seen in 10 years, which a tape measure works well on. I do not have fenders anymore and will just wait until I bolt on the rear arms and wheels later this summer...

On my topic, there is everything to calculate and get the idea in theory

Simple mathematics only.

Stock wheel is 4,5" et34 and the usual empi 8-spoke is 5,5" et30, which fits well with stock fenders.

I dont know how much late 944 arms widen the rear, but this can be found somewhere here at germanlook. I think they widen 74mm total=37mm per side;

http://www.1010tires.com/Tools/Wheel-Offset-Calculator

This is calculated with stock arms, you must add difference between with stock and late 944 arm width and possibly a spacer width.



Adding 37mm it gives these results:



I would also put 30-40mm thick spacer. No doubt the 11cm is best option to rear.

Anyone here actually own and have installed Kerscher rear fenders? Because if you do a tape measure can do ALL the math I really need...
