Just purchased a 323i and am wondering what I am in for? It has 86k on it. Has been BMW maintained. ABS light stays on. How do you reset the service light? I will be doing my own maint on the car from here on. What is a good cheap code reader for this car? How complicated is the computer system? Should I change all fluids? I also own a Ford Powerstroke that uses synthetic fluids, are they the same requirements? What should I investigate before driving very far? All suggestions will be appreciated.  Bud |

This is a question to the forum. I've been looking at the Dinan 3.15 differential upgrade as a possible driveline modification. Is this the so-called LSD (limited-slip-diferential) referred to in these forums, alike the M3s, Miatas or S2000?. The ZHP stock differential ratio is 3.07:1. Does this mean that with the new differential I would have 3.15/3.07=1.03, 3% more revolutions/torque per engine shaft RPMs? Dinan's claim is that 0-60 can be attain without changing from 2nd to 3rd gear. What do you guys think?  Is 4 grand worth 3% increase in traction? Of course the other mods, such as exhaust, cold air intake, throttle body and software would bring the bill to five & half grand, with a possible 22 hp gain up to 257. Not bad. But the Dinan rep suggest do the differential first. Wanna chip in? Basically I can't wait for the new M3, but can't jump into a new/CPO now. So, just started asking about souping it up.  Finally, would this kill the resale value of the car?

Skip Barber practically invented race schools as we know them today. That said, going to that school first would be like buying running shoes for a baby that can barely walk yet ;o) A BMWCCA driving school would be just as good and MUCH cheaper. Read "Going Faster" if you get the time -- you'll learn a lot about Skip Barber and competition driving in general A friend of mine bought a used 3.46 limited-slip diff for his 330ci. It makes a noticeable difference in acceleration and traction while powering out of corners (esp. on slippery surface) but if you don't autocross or track the car, there's no pointing spending that kind of money. He only paid $1,200 for the LSD and installed it himself. Dinan is a good tuner but mostly for people who don’t know what to do with their money -- you can buy everything that they sell for a lot less money and it will be as good and sometimes better. |

Does anyone know what the differences are between the standard and sport suspensions for an '04 325i? Obviously the springs are different, but how many other parts? Shocks and/or swaybars maybe?
