SPS has a steel flywheel as standard. It has a different one to the S as the SPS uses twin pickups for the P8 ECU, and S uses single pick ups for the 1.6M. the SPS flywheel may be slightly lighter, but not by much and its simply because of its design, rather than designed to be lighter, if you know what i meen.? There is a Ferrachi flywheel for the SPS with 4 steel inserts as pickups but the last time i ordered one it took ages to arrive (not much demand to make them i guess) |
