32mm (1.25") diameter. I am installing it now. Don't have to remove the subframe for the s2k, so it shouldn't take too long. Thanks again for the present Mere -- Brian
put pics from my install tonight up in mere's gallery. Tomorrow, I will try driving the car with the stiffer bar and victoracers http://mere.darg.net/s2k-sway -- Brian
Man, put the sway on full stiff last night and went for a ride this morning, and the car really sticks to the road amazingly with the Victoracers, and really has a nice sharp turn-in with the stiff sway. I am going to take the car on the mountain run like this -- Brian
When you put it on the sti, i found that you can install it without dropping the subframe. Just thought it might help you save some serious time on the install. (perrins instructions tell you to drop the subframe but that it so rediculous) Anyway good luck with the sways man! youll love it feels afterward!
I have taken the subframe off of the wrx/sti 3 times thus far for sway bars It really isn't that bad. -- Brian
Not that its hard, just a tip that saves lots of time on the install. I had mine off for the antilift kit and you're right its not really hard, just time consuming.
