I ended up going with the SPC and I'm very happy with them, my only complaint is lack of colour...

This doesn't sound completely far fetched to me. I've spoken to a couple folks with track built cars that use the SPCs without any problems. I think you are mostly paying for looks (and a little over engineering) with those billet mahined arms.
