i've got myself a Whiteline rear swaybar 24 -26mm and love it. but most of my local friends run 22- 24mm.

is there a benifit to running the smaller bar and what.

although i don't know if i'd ever want to change. Plus i have the heavy duty mounts to go with it

 

lighter bars can make the ride more pleasant, especially, or mainly over rough surfaces. Like in rally, rallycross, and offroading, a smaller swaybar will allow better handling. I don't know much, but if u go too big, (I don't know what this is) you'll lose traction, trading it for response. This is true after a certain size, and I thought it was in the 22 range, but it may be lower (or higher) which is best though totally depends on your driving styles, habbits, and where.

 

ya i like the bigger size because while on the gravel it's really easy to pitch the back end out while going around hairpins etc.

 

So...would a perrin 20-24 bar w/ mounts (endlinks?) be overkill on a 98 OBS (stock size = 13mm) even though I have swapped springs/struts already? Or would it complement my current suspension mods?

I've been wondering this for a while now...

 

It depends on your suspension. Don't get me wrong, I won't know given your suspension since I have stock w/ a RSB, but I think no one can answer that question unless they know what suspension you have

I believe its generally recommended that you stay around 18-20 with stock front (for street driving thats more aggressive but not insanely experienced people with oversteer), but I also believe its considered better to upgrade both the front and rear at the same time so you have a matched setup, and this would also allow you to go bigger without having to worry about dangerous oversteer. However, I believe it is mostly dependent on the driver.
