Sway-bar size...?

[Peer]

What's the size (thickness) of the stock front sway-bar on a '98 Box?

I believe that S-spec RoW 030 front sway bar is 24mm thick,the Eibach is 24mm thick as well. Ordering the RoW 030 sway bar with bushings is a lot less then the Eibach,just something to consider. Now for the front your best bet is 2.5L/2.7L RoW 030 sway bar,the Eibach rear sway bar is the same as the S-spec,which is smaller then the 2.5L/2.7L RoW.

Peer, from what I can determine and I am no expert at this is the front stock bar is 23.1mm and the rear is 18.5mm. I believe the '98 and my '02 still have the same size but more knowledgeable minds than mine can testify if this is true or not. Tomorrow afternoon I am having the S M030 front 24mm and rear 19.6mm base M030 installed. I will report back on the difference if detectable. I believe it will lean a little less not that it leans a lot now.

So the stock ones aren't that much thinner than the M030..?

Yes, please do so -- I mounted some racing swaybars on my Eunos, which was one of the best upgrades I've ever done: http://ccrma.stanford.edu/~peer/roadster-swaybars.html

Peer, from what I am told that much larger bars will make a difference. Some have posted the difference is remarkable. I will let you know what they do for me.

Stiffness goes with the 4th power of radius. In other words, a little larger diameter makes a very large difference in roll stiffness.

Lord have mercy, what a difference. I took a dogleg left and right turn at 60 on the way home from having the M030 bars installed and that little sucker din NOT lean at all. For the cost from Sunset out in Oregon, $235.00 including shipping for both bars and $170.00 installation, I would say that this is the most bang for your buck handling wise. I kept my 17" wheels and stock strut/spring set up and you can really feel the difference. Highly recommended if you like fast corners. What a difference a mm makes.
Down side is I found I really need a set of rear tires and I had not provided for that in the budget so some adjustments have to be made financial wise.
