Hey guys I have a 98 BMW 528i. Its got 150k miles on it but it drives pretty darn good. Its got no problem with the powertrain, has silky a smooth transmission, and the suspension compnents are all in good shape. I wanted to do some upgrades on it, so what do you guys suggest?
I was thinking some of the following:
1. Slotted rotors
2. Sport shock absorbers and springs
3. Conforti CAI (anyone have any expirience with this? How are they?)
4. Switching out the 225/60R15 with sum 235-255/45R17-18
5. ECU Upgrade (Anyone know any good ones?)
6. Exhaust (supersprint?)
7. Lightweight Pulleys
Now I dont know THAT much about cars, so maybe you guys can tell me some upgrades that I should consider before doing the ones I listed above. Im not looking for a high-powered beast, but more an all around well-balanced car. Along with being my daily driver, I wish to take it to the track about twice a month.
Im hoping to not spend much above $4,000 on this car, do you think I can accomplish any significant performance gains with that kind of many.
