I agree 100%. I have just the stock gears with my cams and they work just fine. Having gears can allow you to fine tune more...but that depends on what you have Justin do to your car.
Also stay away from HKS gears......Apparently an Evo owner here in Aurora had HKS gears and the gears themselves ground down to a fine point on the teeth of the gears and chewed through his timing belt.....just an FYI. And I spoke directly to the guy it happened to.
