Chassis stiffening/reinforcement

[iceturbo]

Hi,

I'm looking to reinforce the chassis of my I35. The car is my daily driver so a roll cage is definitely not an option.

I would like to know what you guys used and if you found it was a big improvement?

I read that some people think that adding bars would help in case of an accident? What is your opinion on this?

And did anyone used UltraRacing product? What is your experience with this company's product or what did you heard of them?

Thank you very much!

A front strut tower bar and rear sway bar help. Also, energy suspension sway bar and end link bushings for the front help.

Did you saw a good improvement with the rear strut bar or you installed them at the same time so you can't tell exactly what the rear made? What grand are your strut bars?

Thank you!

The rear sway bar definitely makes a difference.

My front strut tower bar is a Cattman TiBar. The rear sway bar is made by Progress.

I'm sorry I read too fast and I taught you had a front and rear strut bar! Not a rear sway bar...

How did you found the improvement of the sway bar? Do you find the back more unpredictable since you installed it? I read that since the 2 rear wheels are less able to move independently, if you take a curve on a broken surface the rear could pass in front... What do you think of this?

Thank you very much!

I don't drive my car like a maniac, but I've run autocross a couple times and driven back country, curvy roads at decent speeds and have never had the rear end slide out. I also have coilovers, so that may affect my outlook.
