Hi - 1st thing is the R1 wing is still in production and will continue to be so.
The R2 wing is no different in material to the R1 as this is proven to be popular all over the world. The strength and durability of these wings are as good as ever.
The R2 is designed to give more side bite in the corner and a lower look too.
Now there is a choice or either R1 or R2 as a tuning aid.
Might not mean much to many but Steve Brown using the R2 wing was the quickest on a single lap by a long way in a field of many excellent drivers. I suppose what I am saying is, it works
