I'd probably like the car a little more if I went back to the stock rear bar, but I'm too lazy to change it back. I'd do it if I had the front working even better (camber arms), but the stiff front bar alone makes a huge difference in dialing out a lot of the understeer.

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

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,

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.

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 :)
