I was wonder if anyone has a rear strut brace installed or is it possible to get one.

this was done on a 2002 SiR

here

 

Seems like it would work on our cars too.

 

What I don't understand is how the guy can claim it stops body roll in the car...it doesn't even touch the suspension. Just the tops of the strut towers. If he wants less body roll, get some better sway bars. All this does is brace up the body to prevent it from flexing as much.

The 3rd gen sedans already have their rear strut towers braced - it's part of the design of the BJ chassis. The Protege5 however does not because it's a wagon/hatch and the rear is slightly different.

 

Auto exe makes one for teh protege 5 you have to find a retailer that sells that stuff and they can probably order it for you. If you search it you should be able to find a few threads on this and where to get them.
