Coolant Bottle

I have run one for years. Just a generic catch bottle from the auto store. There are two main advantages: 1) a lot of tracks won't allow you to run without one; 2) it makes it easier to add coolant, since you don't have to pop the hot radiator cap.

That said, I never liked how it fit (I had it mounted by the horns (close to the outflow pipe) but I had to twist one sideways to fit it. I actually like the milky-white look of a factory-type tank (looks OEM) , but i want a much narrower one than I have found so far. What I do NOT want is a colored aluminum or stainless steel or chrome "bling" job. But that is what seems to be available.
