I utilize HDK on my cars. The fit and performance is unparalleled. And if you have any question at all you get to talk to the owner himself (Denny) he will patiently answer your millions of questions. Ask me how I know. His actual passion for the sport and genuine determination to do what is best for your car has been proven over and over again on this Forum. By same token the previous advice reference asking Trublu is solid in the event you go torsion. He is yet another wealth of knowledge and experience. JMHO
