Are these only for the rear or both front and back?

Most of the time its for the rear, but you could upgrade the front as well for better piece of mine. I believe A.M. Performance has a set of endlinks coming soon.

I got whiteline swaybars...., it improved my track time ...., BUT these bars does not have "lateral lock"...! The rear bar can move horizontally under heavy load.

My car spunt out 180o twice during tracks days in the 2nd and 3rd session.... and at that time I dont know why my car handle very very bad after the 1st session.....! Lucky my mechanic friend came along and found out the rear sway bars moved horizontally (does not sit in the middle anymore).

We tried putting steel clamps on... but it still can move.

We found out that Whiteline selling the "lateral lock" now. Whiteline KLL1_ _ Both Sway bar - alloy lateral lock ..., I will try installing them before the next track day..., let see if this can solve the problem....! I tried to get them but none of the vendors and even whiteline does not have them in stock :shakes head:

The good things about Hotckiss and probably other brands.., they got these lateral lock welded to the bar already.....! However, some people told me that if they got these welded to the bar..., they r gonna be the weakest point...., the bar will snap at the welded point..., is this true ?!?!?! :confused:

hollow vs solid
 

since drive shafts on the cars are usually hollow, I don`t think hollow should be too much of an issue.

Plus one^:tup:

End links are key to setting up the sway bars effectiveness! It all depends on ones driving style (more/less understear/overstear). The sway bars are only one piece in dialing in the suspension geometry for improved handling. Also, check out the spring rate/shock dampening rate (compression/rebound). When I was active in racing indy type cars, we would pre-load the sway bars/change the shocks/spring rates to fit the track conditions. Alternatively, ride along with another Z that has the sway bars your interested and compare it with the stock sway bars on the same road/track.

The load on a driveshaft and the load on sway bars are totally different.

OP: You can't get too much front bar on our cars. Personally I prefer the whiteline.

eibachs!!

:iagree: :iagree:

I have whitelines, but I was wondering which brand (between Whilteline & Hotchkis) at the stiffest setting is stiffer. Anyone have any idea?

Front? how about Rear?

That's how mine are setup and I really like them for the street.

I would hope he would have figured it out by now.
