Is S1 different than S2 for the following parts?
Differential mounts? Is it a straight diff swap from S2 to S1?
rear coilovers? S2 R3 to S1?
rear subframe? S2 R3 to S1?
please reply if you know for sure. I have both, so eventually I’ll find out, just looking to get info before I delve into it.
Thanks

Thanks Loki, just curious as to why the aftermarket bilstein and Ohlins kits have the same for both S1 and S2?

Thanks Loki. That answers one of my questions conclusively.

the S2 differential is a direct swap
there are some minor rear geometry changes on the S2, I’m still not entirely sure what specific parts it takes to accomplish that. The S2 rear suspension arms are a bit beefier than the S1, but the lengths are identical, so whether it’s the subframe, the rear uprights, rear shock mounts and/or chassis positioning of them I’m not sure of.

The upper mount is the same, just the angle of the camera or it was loose fitted. So I swapped the rear subframe from S1 to S2 and vice versa. They fit without a problem. Just the connector for the headlight level sensor are different that connect on the driver side inside the trunk next to the abs connector, so I swapped the sensors too. The reason I swapped the rear subframe is that apparently the differential mounts on the subframe are slightly different between the the two generations. I intend do the lfx swap on my S2 rescue8.

Yes, they are connected. Dannobre pointed out to me that S2 and S1 sensors might have different footage output. I have to swap them and check.
