What did you do for your ZHP/ BMW / MINI today? #2

[Avetiso]

I know a lot of people put a 3.46 diff in their manuals. I wonder what a 3.64 would be like out of the Z4/ZHP auto

Probably a bit much if it's open. I'd imagine you'd have some traction issues trying to lay power down in a turn

I think its okay, my friend had a factory 3.46 in his sport 325ci auto.

Looks like I get to order more parts. :/ Think the expansion tank busted on me. Saw the plume of spray in my side mirror. Coasted over a mile and pulled off the exit ramp, waited about 10 minutes then drove about 500 feet to a safe spot.

Sitting at Mr. Tire in Burke, VA, M&B new sneakers for mama's X5, noticed this week the negative rear camber had just about worn out the inner edge of the rear tires, got 26K miles out of them, ordered 275/40-20 & 315/35-20 DWSs from TireRack which then got delayed by the little east coast snowstorm. Fronts still have good even tread remaining but found out the xDrive system must sense no more than 2-3/32nds difference between any corner or else it can throw error codes, so replacing all 4 to prevent any xDrive problems.

Oh no. Nasty early morning surprise.

Wow, that is a sensitive system to be able to tell the tire wear is different.

Not a fair comparison. The 325 auto has vastly different gearing vs 6MT, only 1 gear share the same ratio.

It sure feels nice to drive it with new "shoes"!
