Try the Soul Function fender brace.

I looked at their stuff. I just don't like the stuff hanging underneath the car like it does. I will not be able to clear anything on the road.

And a cage. LoL.

That is also not a wise decision for a street car. I would need to wear a helmet while driving the car on the street. If something happened and I hit my head on the roll bar it would not be good if I didn't have a helmet on. I will probably do a 5 point RPM rollbar. I am looking at all the options.

I have the RPM 6 point - easily converted to 4 point or 5 point as needed just by removing the side bars.
Some things to consider:
Even tho' I have it configured as 4 point for normal driving I have the seat all of the way back and I'm not a large person. 5'9" and 155 lbs.
Another side note is that it further compromises being able to see out of the back window.
It cost about $2,500 and then another $1,795 to have MA-Motorsports install it.
Brian at MA designs custom roll bars per your specs. That, in my opinion, would be the better way to go. He could design it to accommodate your body size and also allow for better visibility out of the rear window < something you would really appreciate for daily driving.

I am also 5'9". I looked at your car when I took mine to MA. I saw the rollbar and was like, nah. I wasn't crazy about it. Getting Brian to make one won't be cheap at all. I have needed to move my seat up 2 clicks. If not, my foot will come off the go pedal when I get on it. I was going to do the install myself If I get one. Have you hit your head yet. LOL

You guys are some damn runts.

I have an RPM 4 point rollbar in my Z. Bought it from Jenz who used to be on the forum years ago before she sold her Z. I paid $900 for it and her husband installed it for me. I have purchase the side bars and the cross bar to make it a 6 point and NASA and SCCA legal for time trials. The cost for those parts were $550. The fab and install is about $1000. There is no reason with your seat placement that your head should come in contact with the rear bar. If it does you wouldn't notice it because your neck would already be broken. There is a video of a guy crashing in a camaro after reaching 200 mph at a half mile event and walked away from it and he had an RPM 6 point roll bar. It did its job and did not collapse saving him and his passenger's life!!!

I know I need it. Ugg, May just do the 5 point instead. Hmm. Add some safety and stiffen the chassis at the same time.

Well, the wife told me if I mess up and don't have a rollbar she will burry my Arse with one just to make sure I have it when I'm dead. I guess I will getting a rollbar. LMAO. I have been out voted.
