First, what size are you getting for the SP1's or the TE37's?
Second, have you ever seen pictures of Volk's limited edition colors on a grey car? Takata Green and Magnesium Blue both look good.
There's always Orange or Luminous Yellow haha. Time Attack Red isn't bad either.
Three, you can NEVER go wrong with a set of TE37's. Played out? I don't think so. I think they're just a timeless design that won't go anywhere anytime soon.
