I would go with the R version for your application. This will allow you to run mod down to 5.5 if the opportunity ever presents itself and the price between them is pretty small. I have two 17.5 touring cars currently, one with and S and one with an R and am very happy with both. The only reason I'm trying to upgrade one to the pro is to run mod class with a 3.5 or 4.5. The driving feel on both versions (S and R) in my opinion is far better than anything else I have tried (Novak, Tekin, LRP) and the brake strength is far better than the others as well.
