Now you guys know why I only did the front kangaroo bar.

I have the Hotchkis bars. The front is not adjustable. The rear has 2 holes. I have the rear set on soft, and it's still too much bar. It's tail happy at times. Was on 325 PSS's. Now have 345 PSS's on the rear. Hotchkis is suppose to be the stiffest bars. Thinking on switching back to the stock rear Nismo bar.

I also have SPL front A arms, rear camber arms and SPL traction bars. The car seem to behave better once I went to coil overs. I think the best advice I hear over and over again is to change one thing at a time a see how it works. I know every time I add suspension upgrades and get alignment the car gets better. I figure I will start messing with the sway bars once I'm done with the suspension up grades. I got SPL upper and lower bushing and rear knuckle bushing to be installed some time in the next few weeks...then I will tune things a bit.

I also think we are all different to a degree in how drive and what we are comfortable with. Some like a tad of over steer as it can be controlled by a little braking, while other like a little under steer as it can be controlled by adding throttle. Most modern sport cars are setup for under steer because people when they panic tend to hit the brake!!!

It seems you change the Eibach with Hotchkis because while reading your signature (your car mods) I couldn't find the Eibach there .. can you please summarize why? in fact I thought the Eibach will be a good choice for track and weekend not DD thu.

thanks and regards,

The 370's need the stiffest front sway bar you can find to improve the handling. The Hotchkis is just a stiffer bar than the Eibach.

There is no sway bar offered for our car that will make the ride quality so bad you wouldn't drive it on the street. The only reason mine doesn't see more street driving is the custom front splitter that would get damaged by many of the roads in my area.

Wow, a lot has changed since I made that post. Long story short stiffer is better up front and as stated above it will not impact driving on the street. The Z tends to under steer so a stiffer front bar helps to minimize that. Since that post I have added every SPL suspension part possible to my Z.

Appreciate your reply Hotrodz.
And I guess you are using the stock one for the rear? Is that right? If yes, then, Have you ever tried using the softest setting on the rear bar? It might work ..
Well, I am trying to find out why people are not using the Hotchkis rear bar even with softest setting!!??

I currently run no rear bar for track as it helps the car rotate better and which means better traction out of turns. Some run with a bar depending on their wheel and coilover setup. I may end up running the OEM bar to help balance out the effects of my aero setup once I can get her to the track and shake her down. Generally speaking no bar or a light rear bar is will improve track performance.

I was using Eibach front at soft and stock rear bar for few seasons. It is definitely better set up than stock(my lap times improved)..but car was a bit understeery. I tweaked front/ rear balance over the racing season, but behavior persisted.
Few months ago I put rear bar in too( I bought full Eibach set, but was reluctant to put rear one in because of feedback that car will become too tail happy)- on softest setting. I did not get chance to test it on the track, but on highway ramps car feels more eager to rotate and I really like the feeling.
Theres probably no simple answer- it will come down to how you like your car behavior and how will it interact with other components. If you can afford full kit- try it, and if it sucks- ditch it

Correction:-went in for spring cleaning-bar was on the middle setting. Geez, not sure how I survived driving in the winter!

Many thanks for sharing the experience.
Now the season of track here will be over by end of March. So, I will order mine later for next season and time attack competition.

Thank you, true, will try both on and then will decide whether to keep both or only just front one.

Thanks,

Just installed their front bar on my car on the soft setting last week, stock rear bar. Wow what a difference. Car feels so much less nervous in corners, and turn in is really direct.

Didn't feel more understeer as mentioned above. My impression was it dialed in the front roll on turn in so it wasn't just leaning on the outside tire, which meant I had a better understanding of what the rear was doing.

I'd say a front bar is an absolute must for these cars. Cannot overstate how much better it drives.

I thought about getting bars from a Nismo. But after reading this thread I think I'm going with a front Eibach and stock rear bar to go with my Nismo suspension.
