so even though the AMS is thicker and seems to be better built the Koyo is still better? just wondering on the thoughts honestly...
what about just going with the SPL w/out oil cooling? I honestly won't track it enough to really justify the build in oil cooler, thoughts on the SPL with external oil cooler (say a Z1 one) or should i just do a Z1 Koyo w/ Z1 oil cooler without stretching my budget too much?
