I have found that my TC3 is quite sensitive to ride height adjustments, to high the car seems to float or drift to one side on the straight, to low and I scrape the chassis and body. At the track I race at, smooth asphalt, 4.5-5mm in the front and 5mm in the rear seem to work well.
Here are some basic guidelines from a website for RC car handling
Higher The car feels better in bumpy sections.
It can feel tippy, or even flip over in high-grip conditions.
Lower The car feels more direct, and it can potentially corner a bit faster.
It's also harder to flip the car over.
Lowering one end of the car, or putting the other end higher up, gives a little more grip at the lowest end, but try to avoid big differences in ride height between the front and the rear.
Johnny, thanks for info. I have checked on Team Associated's website and talked to my LHS. I will resume my search at NAPA and Home Depot
