What is smallest under body sway bar?

[911st]

What is the smallest under body front sway bar and what rear sway did it come with.

I know the early 3.2 Carrera was 21f & 18r. Where the SC's or late 2.7's smaller and what size were they.

74 911's used 18mm, front & rear. The 911S had 20mm front & 18mm rear.

Correction: 84-85 3.2s had 20f/18r and 86-89 models had 22f/21r.

My 73S had 15mm front and rear from the factory.

Thanks guys. What I needed.

Need to double check.

Is there a 18mm under body front sway?

I thought the bars through 76 or 77 were through the body (trunk).

I have a 74 with the under body unit; that's when the change was made.

Thank you for the confirmation.
