Depends...actually the Greddy T78 would be the best all around. The price being the main attraction. I've recently spoken to two people who has experience with the T78 and an SP kit. Both say the T78 performs just as good if not better. Don't take my word for it. Find out for yourself by asking around or find someone with an SP kit, PHR kit, Greddy T78/T88, and an RPS kit and ask for a ride. Either kit will make you happy. Its all about how much you want to spend!
