I am just wondering since I want one bad and also where can get one. All I have so far suspension wise is springs

 

dont know about quality, but http://www.showstoppersusa.com has em

 

I have the 22mm rear bar on my EM2. I got it from Dezod Motorsports. But Im not sure who would have it for your Si.

It is a very quality part, with an effectiveness of actually doing something for my car, unlike a lot of parts out there. The only thing I would suggest since you are dropped, is to find some custom endlinks, or if Hotchkis or someone already makes them.

Heres the write up, with pictures that I did on the 01-05 Civ Forums. Maybe that will help. Click Me!!!

 

I put on the progess rear sway bar and the tanabe under brace. With both of them the car handles like its on rails. I'm not sure which is making more of a diffrence. But with both the car nose's into corners better and the rear end it alot tighter. Trust me you wont be disappointed
