Sway bars
 

What sway bars is everyone running? And what do you think about it?

Stock TII

Stock front, none in rear. The rear comes out predictably under excess power and is very easy to control. Of course that could have something to do with the rediculous rear camber I had.... Anyway, once I get the money I plan on running RB sways with the stiffer connector rods.

Stock, works fine for what I run.

stock t2.. but im getting the racing beat front and rears w/ the adjustable end links

RB front bar and S5 NA rear bar. Ditched the rear RB stabilizer bar after experienting on the track. May try no rear sway bar next time.

i prefer the stock ones

Running a stiffer front with no rear might produce too much oversteer. It works for me because the front is stock.

I thought running stiffer front with stock rear would induce more understeer?

I plan on going with atleast a Suspension Techniques rear sway bar to compensate for running larger tires in the rear. Maybe try that out for a while then try the front as well.

It is my understanding that stiffer sway bars increase the grip, therefore stiffer rear increases rear grip, inducing more understeer. Stiffening the front would give more grip to the front, reducing understeer. If you get stickier rears, you would want to stiffen the front sway bar to compensate.

Thanks for the advice but I've already spoken to many track veterans who run no rear sway bar at all and prefer it. I'll give it a try and see how it goes. :)

Yeah, I guess a lot of it depends on the suspension setup and tires you have. I was also saying that partly so someone that doesn't know better tries it with bad results, as I was pretty sure you know what you are doing.

generally, if you run no sway bar with a moderately stiff suspension, the result will be favorable, at the track anyway. the lack of a sway bar allows enough body roll/weight transfer to carry the rear end around. Im not sure how FCs react to this mod...but on my AE86, removing the rear sway bar is probably one of the best things i could've done to that car. the balance is alot different on these cars tho.

you are wrong...
stiff/bigger rear swaybar increases oversteer

do a few turns with no front sway....

Will changing to racing beat or suspension techniques sway bars from stock 86' NA bars make a big difference?

Did 86' GX models come with sway bars? Also does anyone know the size of them and if changing them will make a huge difference?

Depending on the thickness, you should feel a pretty big difference.

I have RB sways and endlinks on my vert so I can tell you this.

Vert sway bars are the same as the aftermarket ones RB sells. when we took them off my 88 vert they were the same as the stockers except the RB ones were red. So that was wasted money. I suggest you find someone parting out a vert and get the heavier sways and save a couple hundred bucks. Just make sure you buy the RB end links (front and back)to connect them up.

Thats some good info.
