Just a word about over filling your crankcase. You may experience some blow by on your passenger side valve cover. Here is a suggestion: assuming you are NOT running a PCV valve. Remove your valve cover breather on the passenger side and take some of the material that is used in fuel cells that baffles your gasoline from sloshing around (probably a piece about 3" square by 1" thick) and stuff it inside your valve breather hole (also assuming you have a baffle plate below the hole attached to your valve cover from inside)then place your valve cover breather back in place. Of course you could also use an
oil catch can that is connected by way of a 3/8" hose to a breather cap with a nipple on it. However, if you over fill and do nothing you will more than likely get some
oil that is being pushed out of your breather cap(s) during some of your turns.
Another thing or two, if you ever go to a set of slicks you will think you are superman on a road course. Also, tire selections are not so great in 15" and 17" sizes. You may want to look at the 18" tires especially if you are considering buying another set of wheels. Big breaks will fit nicely on most wheels larger than 15". Good tires and good breaks can usually out perform horsepower on a road course.
