the Whiteline bar is about identical to the Mazdaspeed bar with the extra adjuster hole (which I agree is pretty cheesey), neither is much stiffer than the OE bar, the RB bar is waaaay stiffer

whether a tube or a bar is stiffer depends on the specific diameters you are comparing against the two

you can stop the bar from moving by installing a pair of shaft collards on it, no biggy

 

Oh yes if you can trust the pair of bar clamp on the track... Why not everyone go for the whiteline :p?

It is nice to have adjustable sway bars but how easy it is to adjust it... even in the pit lane? Well you obviously need a jack and tool. Until they have electronic adjuster like the EDFC in Tein coilovers. I am just too lazy to do all that!

 

yes, every NASCAR racer runs shaft collars on their track swaybars , you must be confusing them for something else, they aren't going to move, I'm not talking about hose clamps if that's what you're referring to though people have used those successfully too

I wouldn't go for either, my speedway-style bar makes them both look like toys not everybody is just playing around like yourself

ps: that's a shaft collar laying in front of the bushing assembly, I mistakenly called it a bar clamp though that's exactly what it does.

 

I can report that the lateral stops I made (hose w/aluminum sheet covering & SS clamp) worked just fine - no movement whatsoever - after total about 80 minutes of on-track workout - Here's the vid https://www.rx8club.com/showthread.p...d=1#post909417 made with the RX-8 spinMOUNT camcorder mounting system.

Obviously compared to the NASCAR style bar these are not anywhere near that stiff - but put those on your 8, and it will become nearly un-driveable. But certainly the adjustment system I see in the pics is virtually perfect and far, far more heavy duty (beautiful too!)

For light track use, the Whiteline's are far far stiffer than stock - but I can't compare against the RB - probably similar or stiffer as the Whitelines are solid - RB hollow. Anyway enjoy the show!

 

nice ***umption, but you're statement is incorrect

the center tube comes in several thicknesses, you can make it softer than OE or stiffer than RB by simply swapping out the the center tube if you so desire, it's the ultimate tunable swaybar, since you don't know which centertube I have you're talking out of your ***umption :p

my information was that the front Whiteline bar is tubular, if it's solid then my statement about it being close to the Mazdaspeed bar in stiffness is incorrect :o

 

Couple questions - where did you purchase such a bar for the 8? How much for the parts? I agree that would be the ultimate, if I could have purchased that ... well I would have....but I didn't know where to get it.

Whiteliness for the 8 are solid front and rear, same diameter as OEM front, larger in the rear.

 

unless they are made of some different material (not steel), the Whiteline's should be the same stiffness as the RB's in the rear and 35% softer in the front on the "same as OEM' arm length i believe
