Modification Guide

So you have your new BMW, and obviously you want to mod it. First You must decide what you are looking for (along with many other considerations.) now this bit is important. Your average, factory spec BMW far exceeds the capabilities of your average driver in the road. thoroughly learn the limits of your vehicle Before deciding you want more.

To be very generic and broad, there is:
-power
-handling
-cosmetics

Power: Something like a downpipe and ecu tune is my recommenstion. Catbacks are a very expensive way to get sound with not much power gains. Unless you got nothing better to spend your money on get the downpioe instead. Now If you want to go all out, you get upgraded turbos. But generally an Intercooler, downpipe, chargepipe, ecu tune and high flow exhaust system will satisfy just about any enthusiast out there. Don't get an intake.

Handling: this is a more complex subject - let's start in this order. The first place one should start is by light rims and non runflat, performance tires. Next you address things like a camber adjustment (which will get rid of the factory understeer inducing setup) then suspension. Coilovers are great, but another good option is a performance strut/spring setup like bilstein b8 sport and and Eibach lowering springs. Depending on your driving habits, a limited slip differential will make the difference between a good and great handling BMW, yet for others it's just an expensive mod that many will not properly make use of. LAST, after performance suspension comes performance sway bars. If you're going all out track then youll also want bushings. If you just want good sound without breaking the bank I suggest a muffler upgrade. Unless you're 16 years old and don't care, keep your resonator (it is there for a reason)

Now, for cosmetic this is obviously a subjective task. My opinion is keep the looks of the car proportionate to its power and overall performance, and please keep things tasteful. I won't get into detail on that because IMO performance should be addressed first.

Mein Auto: 2017 330i
Having just leased a 2017 330i, my list is the following.

Power: Will go with a plug and play about $400 for about +30hp.

Handling: lighter rims is a start, however, the cost is not the best way to go, Set of springs for about $250, then another $200 installed then another $200 for alignment. For a good set of light weight rims you are looking at about $1200, then $800 for tires. I'm going for a set of springs on my car, it has 18' which I'm find with. Car needs to be a little lower too much distance between tire and fender.

Have thought about getting a plug and play AMP for the sound system.

Number one on your list should be "Thoroughly learn your limits by taking some drivers training before making any performance modes.".

How many threads have you seen about some yahoo getting into a car that exceeds their skills and making a mess of the car, themselves or things around them?

This should really be a requirement before anyone drives on public roads because over and under estimating your skills and/or the limits of your car are the cause of most issues on the road.

You need performance struts to match your lowering springs. The springs by themselves won't result in optimal ride/handling.

You're very right, and I hope people use their judgement and choose to learn the limits safely. But I've learned the limits of my vehicle on the streets (it's a 528i, the limits are not that high) just like many of my friends did. Is it the best idea? Probably not. Can you do it safely on an empty street? If you practise responsibility I don't see why not.

Only if you are going to race your car, but if you don't plan on racing then springs are good enough for street driving and occasional track days.

Not true. You want to always avoid lowering springs unless you already have performance struts. Do your research.

Everyone that hears it loves it as do all the members I encourage to do it. How's your NA 5 series working out?

Alright man, if you like the sound with a resonator delete I can't complain. You did what you liked best to you're exhaust and that's the end of it. Honedtly, I like my 528i a lot. I modded the exhaust and it honestly sounds really good. The engine is responsive and torquey enough to rip through tiny traffic openings and it sounds amazing. The RWD handling is stellar. Heavy car but looks and drives great. I didn't expect this much from a 528i to be honest.

Outside of never learning how to drive properly, khammack's advice, way too many people screw up a perfectly good car with hard core race parts that have no place on a street car.

Its the old case of following the cool guys with monkey see monkey do instead of actually understanding what they are doing.

Yup... have seen this before myself. First you should learn the limits of your car in stock form. If you're not responsible enough to do so on the street, you take performance driving classes

Dude I guess 20 years of Road racing doesn't give me any creditably on suspension set up.

I agree to a point, but I doubt installing springs falls under the same category as maybe taking a 320i and dumping 15k into and trying to go as fast as a 340i.

Performance lowering springs compress your factory struts too much. Your average street strut is not designed to be compressed this much. It will wear out quicker since it has to work harder (move more) in order to compress. A quick google search of lowering springs and you'll find what I am talking about. For example, bilstein makes these HD b6 struts (not high performance) and they specifically mention that your warranty will be void if you put lowering springs on because they are designed to be used with normal length springs. If you M performance suspension from the factory or something along those lines then you're fine. But otherwise handling, ride quality and overall strut wear would be improved if you have something like the bilstein b8 sport struts to complement the aggressive springs. I also recommend Eibach or ACS springs over H&R.
