Mace said:Where did you get these numbers from??? Most people run more along the lines of 5* caster with larger tires.
5 degrees is usual for larger tires, to get better control and ride, on your vehicle, reazon, larger tires ..
But, if you check any alingment program ( as Bear ) you can see and advice the stock values of caster for our TLCs ... and in the real life you don't need more caster than that ..
