Pardon my french, but holy shit, this setup is boss. This little Isuzu really packs a punch, and you gotta go with the NA Tune, it gives it just the extra torque it needs.
Excellent tune, this setup is Highly Recommended for anyone doing the manufacturer races. It will blow you and the competition away.
Oh and there really is no need for R5 tires, unless you're using this car for a rally race with no tire wear, if you're doing the manufacturer races, just play it safe and use R4 tires.
