An excellent subframe for Monoposto conversions. Considering a used OEM Monoposto subframe is now almost double the price for this piece when new.
Only downsides are that is doesn't have provision for the rear tail seat latch key/lock setup or predrilled holes for the rubber strap pins to hold the wiring harness, & the mounting tabs for the tail mount ecu's should be an option since the 998 doesn't need them for all applications. Other than these, it's a very good quality piece for the street or track use.
