Super Speedway

[chubs29998]

In August of 07 right before my return to college I came up with the idea of building a super speedway out of plywood. So around late october we had the track complete enough to run on. The dimensions are 19ft long by 9 ft wide. The track is 2 ft wide the whole way around. Painted black with a checkered start finish and grid markers. The outer wall is made from door/window foam that is about 3 inches wide 3 layers thick for rigidness. The banking was supposed to be 27 degrees but after completion we took a digital scale to it and it only came out to 25 plus or minus. We have been running on the track for a while now adding things to it like logos on the outside wall and putting pit boxes in the center. I was wondering if anyone had any suggestions on where to start looking for mechanical grip. Thus far my mods have been this: I put a nice homemade wing on that I made from a sheet of aluminum, I purchased the tire sets and found a combination that works well with soft and stock (the hard were like ice and the combination of how they are on my car is my little secret ) What has been running through my mind are ideas about adding a small balast in the car, tuning the suspension with the upgrade and ??? Lets hear your suggestions
