The GTC-R pop up hub was developed especially for competition cars. Any steering wheel and steering boss matching a 3-hole 50.8mm PCD attachment style will comply with this pop up hub.
The GTC-R pop up steering system has a 50.8mm PCD pattern which is smaller than commonly sized 70mm/74mm PCD (MOMO/Sparco/Nardi/Personal/etc.). Because of this, a 3-hole to 6-hole adapter (x2) are required if you wish to adapt a 70mm/74mm PCD steering wheel and steering boss hub into your street car. This adapter has dual 70-74mm PCD hole patterns.
We highly suggest going with a RAPFIX GTC Hybrid Pop Up Hub or Rapfix GTC Tilt System instead as its more cost efficient if you wish to use the commonly larger 70mm & 74mm PCD patterned steering wheel and steering bosses.
