I was going to get Superlight sprockets and DID chain set from: http://www.sprocketcenter.com/p/1216...-51-00-06.html

Would these sprockets be comparable as far as quality and durability? If I were to keep 530, would I need to replace the chain? Would the DID VX which is rated for 1000cc be good enough for my RC51(no major modifications)
