I ran a jconcepts finnisher wing made for the B5, mounted via the to shock mounts. Just have to line up The holes.

Other way I ran it was by running a 4mm longer bottom shock tower screw (the one that mounts the tower to the bulkhead) and 4mm with of spacers. You then mount the wing in front of the tower, with the back of the wing screwed to it.

JN2 Desgines wing mounts. I know the guy personally and have used his mounts with good results.

Anyone use the composite arms for the rb6? Thoughts? Worth it? What about the composite shock towers?

Thx

I run all composite parts in my second RB6 which I only use on carpet/astro. These parts are lighter and flex less so I have found that help the way the car handles on high traction surface.

They are also lighter so if you run stock you will lose a couple og grams too

I run on that exact surface with all composite parts and haven't had a single issue. Also I don't crash much either which helps.

Did you lose any grip? How does it perform compared to stock arms?

Everything should work. Main changes are in the transmission options.

I'm not sure about your exact question, but probably no. The chassis changed slightly (the sides and side rails), but as far as I know all of the geometry is the same.
