Terms like 'Good' or 'Best' are too vague. Each car is different in their goals.

With that said if you're looking for a complete kit that will take a weekend or less to install you're best bet is checking in with Hahn Racecraft. They have a few different stages of kits that would suit your needs. You can also check various forums for members selling their kits, it's hit or miss though.

Otherwise you're looking into building a complete custom kit from the ground up. Which means acquiring all the necessary parts from several different vendors. Many have gone this route, but this is obviously a drawn out process and most who go this route do not finish the setup for monthsor even up to a year if not more.
