• Mazda RX7 Wisefab Lock Kit

  • For Mazda RX7 FD (1992 – 2002).
  • Steering rack at original position can be used or it can be lowered 10mm if needed.
  •  62 degrees of lock, parallel steering. You could tune your steering geometry either towards positive or negative Ackermann in just a few minutes even at trackside without messing up an alignment.
  • Adjustable lock stopper.
  • All the steel components on Wisefab RX7 front suspension are from high strength steel, including sheet metal components, tubes, tube ends and rod end housings. Rod ends and spherical bearings are used, no rubber bushings.
  • Higher roll center (RC). RX7 has a double A-arm suspension, which is a very good starting point for a racecar. Lowering the car would increase performance and handling, but this would mess up the original factory designed kinematics. It lowers the roll center and increases camber gain.  On Wisefab knuckle, both joints are dropped, which brings the front RC up on lowered car, providing higher roll stiffness,  good camber control and minimal bump steer with high steering angles. On drift cars the dynamic camber and bump steer is much more important than static. With our kinematics we have assured that the camber would provide very good front grip and bump steer is minimal at all the range of steering.
  • Steering jacking control. During steering the car chassis is moving up and down – this is called jacking. Steering jacking is caused by combination of caster, KPI, trail and scrub. On road cars, this effect is used sometimes to balance the car or to help to turn in. During drifting, when steering angle is much bigger, jacking is also bigger, even with the same geometry and it could become a problem. We have changed the geometry that it doesn’t cause any handling issues.
  • Consistent and predictable self-alignment torque. Caster is not the only important parameter to provide sufficient self-alignment torque especially at high lock. It’s the combination of different parameters to maintain consistent trail and self-alignment torque. With our setup the steering wheel turns always to the direction of movement and doesn’t get stuck at full lock. 
  • Original sway bar can be used in front

  The kit is designed and manufactured the way that after installation and toe adjustment it’s ready to use right away.

Other components, packaging and clearance. 

• This kit assumes coilovers to have enough clearance.
• Ride height is designed to be ~80mm from front subframe to ground.
• Dependent on rim width and ET, wider fenders or fender flares would be needed.
• Inner wheel wells do not need to be modified with tire diameter up to 635mm (215/45R17, 225/45R17, 235/40R17, 225/40R18 etc).
• Minimum rim diameter is 17”.
• Recommended backspacing is ~135mm (7“ ET45; 8“ ET35; 9“ ET20). If ET is smaller, then wheels stay more outwards, if ET is bigger, then spacers need to be used.
