I really like your 745i. Interior has come up very well and those rear seats have full electronic adjustment it seems. Mine has the little button under the rear seats for adjustment. I'm looking at a shorter diff. I have the non LSD 3.25 auto and it's way too tall. Needs at least a 3.73 as it's an auto with the high comp b34.
I have also a warchip waiting to go in and are wondering if anyone does a transmission chip that moves the shift points slighly higher
