| According to jasper's post, the SP5 has the same transmission as the 748 and the Strada/SPO has the same gear box as the 916. BTW, 15/36 is also stock for a 916.
So a good choice (just like for a 748) for the final drive would be 14/41 for the higher-revving SP5 and 14/36 or 15/39 would be best (just like for a 916) for the Strada/SPO on the street. |
