How wide a wing? (late 944T Arms)

[Wally]

Hello,
I run the wide turbo alu arms as well and have 8x16 993 rims with ET70 and 225/50/16 tires in the back. I needed wings that were 5cm wider, but Kerscher only makes either 3cm or 7cm wider wings.
Therefore I used the 7cm wider wings (inside and outside widened) and used a porsche spacer which was + 2,5cm.
I hope this gives you some reference.

Greetings,
Walter
