Thinking about upgrading myB6 S4 rear sway bar (20mm) to an OEM RS4 rear sway (22mm). Would the extra 2mm thickness make much of a difference or am I just wasting money? I just want to dial out a little bit of understeer I'm feeling driving around town.

Thinking about doing this instead of the H-Sport route due to cost constraints...

Thanks!

..maybe 41R if it's only for the street.
What kind of tires you running?
You can't get it any cheaper than FREE.

I'm running 235/40/18 Hankook Ventus V4ES tires. I thought about that but I'd rather put something in more "permanent."

Anyone do a swap to the RS4 bar on their S4s? Noticeable differences?

How much stiffer is a 22mm solid vs. a 20mm solid bar? Same difference as a 24mm hollow (like the H-sports) to the OEM bar?

Cheers!

thanks! ygm back....

looks like the OEM B7 RS4 rear sway (22mm) is around 35% stiffer than the OEM B6 S4 rear sway (20mm).

Would this be enough to make a difference in conjunction with increasing front tire pressure (or decreasing the rear psi) on the street? Probably so!

agree.
