I put a Whiteline Supra bar (part # BTF76Z)on the front of my Celica today. It fits surprisingly well! It has a unique end link arrangement and includes some brackets that bolt to the control arms. Looking at the instructions, I believe I have them flipped opposite the intended direction. With that "modification" it bolts on like it's made for the car. The mounting holes are back a bit further than ideal, but the end link arrangement makes it work fine. Just thought I'd share my experience in case anyone else is looking for an adjustable sway bar option. I'll let you know how it works out when I get it out to the next autocross.
Also changed out my springs. Lowered the car about 2" all around and went to (gulp) 1000 lb/in springs in the front. I really don't understand it, but the car was still rolling quite a bit with 800 lb/in springs. We'll see what happens. Ride on the street didn't change at all. The suspension doesn't do anything, it's all tire. But when I race, it still feels a little "boaty". Had to wait on a special order for the 1000 lb springs. Not sure if I can go any higher! But, hey, now I can say "I have a ton of spring in the front of the car".
