Sway bar options - Whiteline Supra bar
« on: Jun 30, 2013, 02:25:48 am »
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".

Take care,

Ed

Good info, wonder what car it is for. If you up the spring weight that much but still feels squishy I think you need to look into stiffening the chassis. The Chassis probably flexes quite a bit.

I'm sure the chassis has some flex, but the car is just rolling a lot. Well, a lot for an autocross car.

what kind of chassis bracing are you allowed to do in your class? I think it's worth exploring since making the chassis stiffer can't really hurt.

have you ever heard of spray foam in your sub-frame? ae86 guys do it all the time just drill a couple small holes through out it and then spray the expandable foam into the "frame" on the car

I know in rocker panels it holds moisture to the inside of the metal, causing them to rust out extremely quickly...

there is a long topic on the polyurethane foam debate, pros/cons etc. I think it's one that I started :heh:

Can I ask who you are having make the custom springs for you? I am wanting to do the 2" drop. I also have a GTS which will make a difference, thanks

I wonder if you upped your dampening(stiffer shocks) on both bump and rebound, if that would help make it feel less boaty. The high spring rate and floaty feeling screams under damped to me.

 :agree:  That extra mechanical energy is stored in the spring, turn it into heat in a damper.
