I use
Future Fab Knuckles on my race car. Combined with one Big spacer on the passenger side, and a smaller spacer on the driverside of the steering rack it feels awesome. Another reason i like their knuckles over other brands is because i dont like twitchy steering also known as "quick steer". Which especially on the street car is no fun. Drivers like Joe Haven, Mike Burns, Corey Hosford, Forrest Wang run the same design.
