Lmao this comes at the perfect time. I've got my winter tires on, and this was the last season they had enough tread to be proper winter tires. So I've been running them down before I put the summers on. I'm buying this ASAP and running these things down bald hahahaha. With the msport diff as well this shits gonna be lit

So I'm doing a little research on how much I could mess up my car. The M40i has the ATC13 transfer case. I looked up where this has been usedz and it's been used on the G12 Alpina B7. This car has the N63B engine, which in this model puts out 600hp and 590 ft-lbs of torque. So this transfer case has the ability to hold much more torque than our cars have stock, and probably more than what they have tuned.

These transfer cases are good for a lot of power no need to worry in that department. We’ve pushed 1250hp and 1100tq on the stock transfer case in the g80 which shares the f97 transfer case

transmission slipping when over that 650 ft-lb torque range. What component is liable to fail at these power figures and would an upgraded torque converter by itself lend to any longevity? |

Let’s say you wanted to bullproof the drivetrain I would upgrade in this path. 1. CF driveshaft with rear diff bolt fix 2. Stage 1 transmission upgrade if you are going for bigger power and want the trans to hold up. Now while your here I would say do the torque converter. 3. If you are at this point of upgrades then I would say most likely axles but no one has been high enough in power yet to test the axle strength of the x3.
