Is it ok for my strut brace to push against...

p.s phat teg RtN

Cusco is a good product, I'd get one for my AH but can't justify the $

If you've got the cash get a Cusco

cuco is like only 60 more than the ultra racing.. 270 is a lot for a little improvement.. i might try getting a cold air intake kit first.. but its soo hard to find any proper intake kits for a da9 here in aus.. its like the forgotten honda model

Cusco is typically made of aluminium and not as rigid than the Ultra Racing. I know someone with a curved cusco strut bar. LOL

whats the U.R one made out of

so yeh despite the flattened corners of the UR bar I think this should be suffice, well it feels like it anyway.

its a waist running the OEM bar at the same time man. The UR bar will do all the bracing before any load is even transfered into the flimsy OEM bar.

Its just taking up space and adding weight.

I suspect mild steel under that paint. That's why it is cheap.

x2 i'd guess the same.

Personally I'd run both, the stiffness from each brace is cumulative, and there can never be too much rigidity in a chassis.

There's nothing wrong with it being mild steel, and I'd be amazed if any similar products were made from a 'higher' grade, i.e. my bet is that (other than the aluminium ones) they'll all be mild steel, which is a very suitable material in this application.

Nothing will be gained from using a higher grade (or heat treated) steel because all steels (other than some rare exotic alloys) are just as stiff as each other, to within a minute and utterly insignificant difference.

The 'modulus of elasticity' is what defines stiffness, and it's very similar in just about all steels in just about all states of heat treatment. The 'elastic limit' is what defines the 'yield point' of a material (how much it can be flexed before it becomes permanently bent or breaks), and this is what differs substantially between different steels in different states of heat treatment (along with hardness).

Only if the tower brace were subjected to significant flexure would a higher grade be useful because it could be deflected more before it permanently deformed and possibly be more fatigue resistant, but a tower brace that flexes isn't a good tower brace...

yeh.. what johnL said abt the oem strut.. and also the corners of the UR bar are like bent flat making it weaker and yes they are cumulative so the load is spread evenly.
