Anatomy of the FRS/BRZ/86 Body structure...

[Moto-P]

Snips from REVSPEED Video 36. Anatomy of FT86 revealed in some ways. Techician describes the body structure is extremely rigid. First, obviously from the huge B-Pillar as shown here, but also, the metals used on the unibody is light, but is unusually tough to cut or drill, or extremely strong. So much so to the point where, in constructing the D1 race chassis for Hibino's UpGarage car, the drill bits used to stitch weld, were getting dull very quickly and prevented the holes from being made easily. Interesting!!

Apparently, it is a very advanced new steel developed for Toyota, which is very expensive, but used in many places throughout the BRZ/86/FRS body structure.

Furthermore, the body stamping and joints are so precisely made that all of the jointed sheet metal surfaces mate very accurately, making the task of advanced race car building an easier task, saves weight, and helps keep the rigidity up even more.

While the crossmembers, suspension arms, and peripheral parts of the chassis are made of very lightweight and seemingly not so strong parts, the unibody structure being so very rigid, they report that the car is really a tuner friendly car. Where in locations and parts the users cannot easily modify (unibody,frame, and basic shell outline), it is very capable already out of the box, and where the users can indeed swap parts easily, and third party to make (arms, rods, joints, etc) there are many ways a tuner/constructor with some talent and resources, can customize to make it behave and tune in further directions as required.

Hmm I wonder what steel it is. Looks very nicely made. Wonder how layered it is

[ESBjiujitsu]

looks amazing!!!!

I think firefighters are going to absolutely hate this car once the ricers start drifting themselves into ditches and regularly need to be rescued with the jaws of life.

Materials Engineering ftw!

With this new steel and Subaru's Ring-Shaped Construction on the chassis, I can only imagine the safety ratings are really high.

Btw, do we know the safety ratings?

That B & C triangle structure looks massively strong. I'd love to see Top Gear drop one on its roof like they did with the Saab and BMW 3-er.


Any more pictures? This is a time where more is better. :happy0180:

Haha yeah true
I also wonder if the layers are simply welded or of they are folded as well. I need to strip one lol
I know when I drilled my doorsills to put the skirts in to the 8 there was a soft outer steel and a very hard inner one that blunted one drill and snapped another one. I proceded to shorten all of the screws I had so they don't touch the hard frame underneath lol
