Friend wants to sell me some fake prostars and drag radials that look brand new pretty cheap.
But they are 15x8 and 4.5" backspacing 0offset, will thye fit with grinding?

you will have to grind to get them to fit regardless of the spacer. The amount of grinding depends on the exact brand and style of rims they are. Also 5.5" backspace on an 8" wide is what you would want for the rear to keep it at the edge of the well. 4.5" backspace may give the car the roller skate look. the brakes on an LS1 f-cars were never designed to clear 15" rims so fitting a 15" rim is always tough unless you spend to get custom drag wheels or get drag brakes or downgrade to LT1 brakes.
