^ no problem

it's just a highly over exaggerated thought that a diff change makes it unbearable. BMW put the 3.46 in the manual 2.5L convertibles and wagons, so it's nothing BMW wouldn't do.

It's less than 10%. The 330 makes more than 10% more torque than a 325, so a 3.46 won't cause a 325 to beat 330s

LSD may give an advantage in things like auto cross, but it will do nothing for power. Auto cross is all about skill anyway; there are folks here who would school me in my M3 while driving stock 323s

some of us by a 325 because they looked for a 330 mt for over a month and couldnt find one within 500 miles with low miles in a good condition....there are a lot more 325 mt rolling around than 330mt. Then u could stop telling people that u don't know why they bought a 325 and give them good solid advice how to make the best of their purchase.

Sure, as a previous 323 owner. Maintain and drive the car, don't waste money trying to get power out of a 325. It's a nice driving car as is, and money spent on trying to get horsepower is wasted. (I did intake/software/power pulleys and it didn't change anything but the noise)..

I'm happy with my 2.92 diff. There I've said it; I have no plan to jump up to a 3.46 rear!
Reason being that my 3 liter has enough torque to make my first gear almost unusable now at full throttle.. If I went higher on the diff ratio, I'd be rushing to shift out of first around ten mph!
Put any rear you want into your 325 and I'll pull ahead on anything longer than 0-25 feet!

Ask (most?) wagon owners and they will confirm that it certainly doesn't make it unbearable. 80MPH is almost 3700rpm but you quickly get used to it.

I was considering doing a rear end swap and headers. Those 2 put together you may feel a little something.

Best thing you could invest in is a rebuild on the VANOS system.

Get used to a lot that I'd rather not endure.

drip, drip, drip, Chinese water torture




I love gliding along in overdrive with the 2.92 rear
gas mileage is great too

I totally believe in 'to each their own'

My previous vehicles (ITR and S2K with high revving engines) had slightly aggressive gearing that resulted in high RPMs at highway cruising speeds. That makes it easy for me to accept the gearing on the Touring. Like you said 'to each their own'...
