SWAY BARS FOR STI

My driveway means I exit on an angle all the time. So I always hear a twisting sound from the rear suspension and the front glass. Since I did the type 2 lower brace,..that sound is gone,.it really does tighten the car up alot. and the overall chassis feeling is better, as though you made the entire platform stiffer, which is what you're doing essentially. Of coarse we carry it and stock it.

Bolts shown on the 2nd pic down are quite difficult to take off...Make sure you have plenty of leverage and use the largest socket wrench you got

Sorry to hear about the stripped bolt. I'm glad you figured out everything! If you have any more chassis/suspension installs in the future, feel free to PM me because I may have pictures that can help you.

Damn, the same thing happens to my car when I angle in and out of my driveway. Very annoying and I've been looking for a fix.

But, will this brace increase understeer? I currently have prodrive springs, cusco f+r strutbars, and perrin f+r swaybars and endlinks. The rear sway is set on the stiffest setting, while the front is set on the softer setting. Right now, I am happy with the turn in I'm getting with this set-up. By stiffening up the front a bit more, will it reduce the oversteer in my car?

You will like the results if you install the v2 lower arm bar.

Technically the undercar braces will reduce oversteer/promote understeer, but it's such a small amount that you probably wouldn't notice it. It's merely a chassis stiffener like strut tower braces, except it's placed in a much more strategic and effective position.

I NEVER had/have the feeling of increased understeer with mine....quite the opposite 'cuz the car 'points' better.
If the car understeers anyway, due to whatever, that may be amplified...but not in my experience.

Yeah i never noticed any with mine. Tanabe Sustec Underbrace. Slightly different mounting points (still connects both sides of subframe though), but same general effect and idea behind the product. Everything just feels more planted and soild without increasing NVH at all.

I just got one of these bars yesterday and I have an install question for you. I notice from
your pictures that you car is on jack stands. Is it a requirement that the suspension be
unweighted when you install this brace? Thanks.

It actually needs to be sitting on the ground when it is torqued. Per the 2002 Impreza FSM page FS-17 (copied/pasted) :
Quote:
5) Tighten the following points in the order shown
below when the wheels are in full contact with the
ground and vehicle is curb weight.

Tightening torque:
(1) Transverse link and stabilizer

Sedan Turbo model:
45 N-m (4.6 kgf-m, 33 ft-lb)

Except sedan Turbo model:
30 N-m (3.1 kgf-m, 22 ft-lb)

(2) Transverse link and crossmember
100 N-m (10.2 kgf-m, 74 ft-lb)

(3) Transverse link rear bushing and body
250 N-m (25.5 kgf-m, 184 ft-lb)

This would explain why my 10 inch socket wrench could not loosen
this bolt. Thanks for the info.
