Default losing tenths due to larger wheels

How much is 20" rims going to slow your 1/4 mile time down compared to stock 16" wheels on a z28?

With such a small *** sidewall on your 20" tires, you are not going to be hooking under 3rd gear. Why you going with a 20" wheel? JMO, 18" is the largest i'd go if you want to maintain traction. Especially launching with an M6!

Four things in this case will contribute to slower 1/4 mile times:

Increased Unsprung Weight
Greater Rotational Mass
Increased Overall Gear Ratio
Decreased Traction
