JFR-200
The JFR-200 is the ultimate transmission for any small, single-seat race car requiring the latest innovations in drive technology. JFR is designed for the premium-quality end of the compact racing car market, as the `smaller sibling` to the prolific FTR-200 transaxle unit (used in F3, Star Mazda and Formula Ford to name a few).

JFR-200

While internals remain almost identical to the FTR unit, the JFR design does away with the integrated engine oil tank to provide a lighter, more compact design. The resulting front face will retro-fit to the popular LD-200 mounting.

The JFR-200 is available in either 5 or 6-speed variants, both with sequential shift and full semi-auto system compatibility. As with the FTR, free or Powerflow differential options are both available.
