B7 S4 Avant Rear Sway Bar

[AudiKilla]

Does anyone know if the rear sway bar from an S4 avant is the same as a normal S4?

Is it 20mm?

I am thinking of getting S4 rear sway bar for my non-sport suspension B7 A4.

Avant/sedan are the same. The later 07 and '08 B7 S4s came with a 22mm rear bar while earlier ones had 20mm. If you're going through the effort of upgrading, I suggest you just buy an aftermarket bar. Personally I like the 034 unit. Shipping is free through ECS if you add $6 in miscellaneous items to pass the $200 threshold.

I'm actually in Canada was getting the 20mm sway bar for next to nothing. But I'll see if someone has the 22mm one here.

IIRC I got a RS4 rear bar (24 mm) from the dealer (in 2011) for under $150.
