Not very good for a daily driver but a hoot on the track.

Best if used with Cup shifter linkage. The dreaded 2-3 shift is no longer an issue with the Cup linkage.

Furthermore, 997 GT3 variants have steel synchros on 3rd through 6th. Only 2nd gear steel motorsports synchros will be different on the Cup Car, as most of them have standard synchros on 1st gear.

As for exact gearing it could be anything at this point. This box could be up to 10 years old and depending on the life it led could be regeared or has had gears replaced. Only the seller will be able to accurately comment on the gear stack though it's sure to have the 4.0 ring and pinion set in it.

It will likely have a 40/65 4 plate motorsports LSD, but with a cast body, just like the body in your 997 GT3. They didn't go to a billet body until a couple of years into the sequential box.
