27mm front
22mm rear

3 way adjustable

Tanabe sway bar are hollow but in chromoly... Lighter and bigger.

30.4 mm / 22 mm

how are you liking the Tanabe bars?? i may get them perhaps. have you gotten the cage in yet?? did do anything for rigity?

*HaLo* · 03-09-2005, 11:07 AM

The cage is in, the sway bars are on..

But it snowed all last week. now, I am kinda stuck in my garage.

I test drove the car on monday morning and it is incredible stiff, with the 7/5 springs on the D2 coilovers. but that just first impression on the street.

I don't like the front part of the cage. the roof bar is way too close to my head. I will be shaving that part next winter just to keep the roll-bar.

tanabe it is then. especially if they are made of hollowed chromoly tubing and the larger sizes. I now I can get whole direct pricing. yee-ah.

nlzmo400r · 03-11-2005, 05:37 AM

yea the front is larger, but the rears are the same size. Seems to me with a considerably larger front back, and the same size rear, all you're going to do is induce understeer. I mean the chrome moly is nice, and the weight loss is cool, but i dont want anymore understeer than i already have. The tanabe's arent adjustable either are they?

*HaLo* · 03-11-2005, 07:11 AM

Understeer can be corrected with negative camber, damping and tire pressures.

Adjustable sway bars most of the time stay full stiff on a track.

And the Tanabe sway bars are stiffer (chromoly) and lighter than the stock units...

nlzmo400r · 03-11-2005, 07:25 AM

yea but i usually dont have time to get my car re-aligned before and after every autoX, much less the money for that. Sure i can adjust front camber from the plates, and can play with tire pressure, but its still wont be as neutral has i'd like.

*sykikchimp* · 03-11-2005, 01:32 PM

I like having adjustable sways.. :-P very convienent.

*DJPimpFlex* · 03-11-2005, 02:55 PM

the sway bars are hollow, so the sizes dont matter that much. They increase the inner wall of the sway bar to increase rigity and the cromoly is stiffer than regular steel. also the hollow design is stiffer. So the 22mm rear doesnt mean its any less stiff than a 25mm rear. Drive with these and you will know what I'm taking about.

nlzmo400r · 03-11-2005, 08:18 PM

the hollow bars aren't stiffer. A hollow bar is actually less stiff than a solid bar. The only reason hollow bars are used is because while they are SLIGHTLY less stiff than a solid bar of the same size, they are much lighter. Having the much less weight offsets their being hollow and loosing some stiffness.

*sykikchimp* · 03-11-2005, 11:47 PM

slightly, as in not at all.. bar diameter, and length of lever arms are the only things that determine asb stiffness. Having a hollow bar allows for greatly reduced unsprung weight, which translates to a faster reacting suspension. This make the car less skiddish, able to 'grip' the road better. The down side to a hollow bar is that it would have slightly less wear life, and it's not as strong. your much more likely to bend or warp a hollow bar than a solid bar. As unlikely as that could be unless you hit something.

if you would like to learn more, check out whiteline's website. They have some GREAT articles on how swaybars, and suspension actually work.
