So I was considering getting Eibach F & R and putting front on full stiff and rear on soft. My car is a street car, that will probably see some autoX. Would you say I should get Hotchkis Front instead then?

I looked at Whitelines but got mixed reviews from other members.

Running super stiff front sway bar. No sway bar in the rear. I M O your front sway will carry through to the rear. You want the rear to be a lil soft for full contact in the corners.

Running Kw3's with Custom valving and modified SPL A arms (before they came out with the official 370 z ones)

also running 18x10.5 square setup with 1" spacer in rear. tire size 285/35/18

All work was set up by Robispec. He does very good work !

soooo doesnt the chart homor posted show the hotchkis as significantly stiffer then the whiteline? on top of this you run a pretty heavy stagger with a narrow front tire, which is what i use to run too and the front whiteline on full stiff was enough, then i went square sizes and it really exposed the front Whiteline as too soft partnered with the KW V3 off the shelf rates. Speaking to Doran, they ran the Hotchkis before they made there own bars because it was the stiffest, they said it themselves.

in regards to GSS138 backing me up, for one he knows me from being in the same socal track scene, he backed up up cause he knows that im not some forum know it all who just talks outta his ***, im actually out there tracking and testing, using my knowledge base of suspension tuning from years of being on track...UNLIKE yourself who drives in the mountains...:driving:

Par for the course with Synolimit. He knows all. ;)

Also, Doran actually did a shootout with a torsion test on most of the common retail bars before making their own. BJ has posted some of that information here somewhere, I remember reading the numbers in lbs/inch for various bars.

(Like Hotchkis front was ~990lbs and their bar they made is like 1600 or something outrageous.)

And who made that? How does a bar with a surface area 21.5% larger have a weakness of 166% less? I said I like stuff "like" homer posted because its simple data you can see. But the back half I don't like because it makes no sense to see those types of numbers. Hell even the stillen is 37% stiffer yet has an even greater gap with surface area. Unless WL is made from silly string I don't see it.

I'm not taking out my ***, I'm not looking for help or crying, I could care less how well respected you are, I don't give a rats *** about you. All I said to start this was I don't care for an opinion and don't see one bar being better than another when the data isn't there. Simple, to the point, bitch on.

Syno, I'm guessing you don't have an engineering background since you seem very confused on how deflection calculation are made. The "I" column in the chart is "Moment of Inertia". It plays a huge role in how much something will deflect (how stiff it is).

fwiw I have a degree in mechanical engineering so I do know a thing or two about these kind of things.

I understand that. Even plugged the numbers in myself so yes I see long bar vs long bar there is a difference. But if metals are not the exact same and mounting points are not in the same location (WL is adjustable, hotchkis is not) then we don't have a winner. we still need to see torsion testing on the actually bar and not just a round piece of tube numbers. That's why I like the chart, just not 100% and why I still like data vs opinion.

When you test it on the track you test the entire solution, driver, car and the part that has been changed.
