Features & Product Details

Cusco is one of the pioneering companies based out of Japan that has invested countless hours of research, design, and engineering to develop quality suspension and performance products that will improve your driving experience. Some of the fasted cars around the world who compete in time attack, time trials, and other racing avenues will more than likely have a Cusco product on their car.

This page presents the Cusco Type OS-T Triangle Bar. This bar allows your Type OS rear strut tower brace to become a 3 point bar by attaching to the floorboard as well. The fit and finish of the Triangle Bar is the same as the Type OS strut tower bar. It comes with the hardware required to install and will require holes to be drilled to complete the installation.

Note: This bar requires the Type OS Rear Strut Bar in order to be used. It will not work without it. The Rear Strut Bar is NOT included.

Cusco Triangle Bar Type OS-T ( Part Number: 660 544 A)
Cusco Triangle Bar 3 years ago
5out of 5stars

Was not that bad installing with the cusco strut bar all together. Took about 1 or 2 hours? My trunk is all ready empty. Anyway here in Quebec we antirust our cars with crazy oil treatment and that was a pain to install that plate with the 2 studs, oily arms it was. Installed front strut bar as well and the car really felt planted in corner and offramp, more direct. Did feel a difference!

Noticeable difference with this on with the cusco strut. Precautions when installing... When you're installing it on your car, make sure and I repeat MAKE SURE you have it in the correct spot. Drill the two holes more toward the rear because underneath there's not a lot of room for that metal piece to fit in, if you mess up you won't be able to use that piece. Which is what happened to me so I had to use bolts and washers to hold it in place.

      A:  Yes they do include instructions, and I actually have seen even better forum write ups that are a bit more detailed as well.
