Those bars are made for a purpose. Thats drifting. Not street driving. They help to avoid damage to the sensible and weak components you find in Front and rear sections while beeing more rigid then the OEM crash bars to safe some time and money for the drift guys. This is nothing what will realy work for a street car. Usualy one tries to avoid having multiple smaller contacts to other cars each day. The bumper will be scraped anyway and even more likely if your running a crash bar. Only very few situations in a every day driving accident will turn out in a way that a drift armor will help you.

Also it is quiet questionable if runing this modified crash bar is legal in your region. There might be some where this is no legal issue, but Id tend to say that there are far more where it would be an issue. And, as said before, the load to the chassis/frame of the car will be even higher at crash if your running a strengthened bar since more load is transfered and less energy is absorbed by the deformation of the crash structure.

I definately dont want to say that those bash bars are not good. They definately are good, but only for the purpose they are meant for. So if you are looking to build a drift missile, you're on the right path. If you are building a street car I would overthink this decission, at least for the front.

In the rear the story is a little "special" for the 86 chassis. There I also was considering a bash bar, even if Im driving a street car. Why? Because the factory crash bar is a joke. If you ever had one in hand you'll know what I mean.

BTW overlapping of crash structures is a big issue in the design of passender cars since the first crash tests where made. Until today there is no real standard for size and position of them. This isnt even realy feasible, since it would create limitations which would be nearly impossible to be handled. With other words: If you crash a car like the 86 with something like a van, pickup or truck this will always be a big issue, no matter what kind of crash bar you are running.
