Rear Strut Bar, Any point in having them?

Nope, useless IMO. As Gav says unless they are mounted/attached to the chassis or something like a roll cage then they will do nothing.

 

The front Cusco ones can be handy with the cylinder stopper, that's about it though. I have a TRD because it looks good :D

Can you use a rear strut brace to mount harnesses?

 

I certainly wouldn't. The topmount nuts are only really there to hold the damper in place, not to take any force. The rear strut is held on by smaller nuts/studs than the fronts also, this would mean it's weaker than the front one.

 

You can buy a proper bar that mounts onto where the seatbelt mounts are IIRC. Uses much heavier bolts.

That was my plan anyway just wondered if i could do it using a strut brace as i imagine that'd have been a cheaper option.

 

Well it's all going to be down to the shear strength of the strut studs. I'm not so sure they would take 40st (theoretical maximum) pulling at 70mph+ without something giving somewhere.

what about the Do Luck body brace?

 

i have one of these, are they just for show aswel?

 

and also have the front strut & cusco master cylinder stopper....

 

Is that the cross brace that is underneath? It will probably be a bit better as it is attached to the chassis. If it is the one I am thinking of I think some people install them on aerotops, doesn't make it perfect but it makes a difference if the reports are true :)

Carbing do a rear brace that bolts to the floor as well as the top mounts and there front brace has the brake stopper built in

 

Although the rear is very hard to find, I am struggling anyway

 

Facelift supras have additional bracing in the rear that bolts from the topmount into the floor. Is it the same area that it bolts to? Any pics?

So does that mean the front brace is pointless?

 

In my opinion yes.

 

The only way they would work is if they were 4 point mounted to the chassis itself.

 

Think of it as an anti roll bar. They mount via 4 points, take the 2 chassis/subframe mountings away and the bar becomes useless therefore losing all front end stiffness ( no pun intended ;) )
