Self explanatory really. What's the best thing you've done to your 3 Series that gave you the best value for money and what was the worst / most disappointing?

I'll start the ball rolling:

Best
Short shift gear lever in black leather. Feels great in the hand(!) when changing gear.

Worst
New 'silver' front E90 LCI indicator bulbs - they look less orange than the standard bulbs but not really that silver either. For £30-odd I was disappointed. If they'd been a fiver...

Best: Error Free UHP LED License light from F1 Autohaus
Worst: Nothing yet

[chinoxs203]

i would say exhaust. besides for making the car sound better, its the smallest performance gain and one of the most expensive mods to purchase for the car

[jeveryday]

Best:
H&R Sport Springs - gave the XI a more aggressive look and sporty ride

Worse:
Rep Hamann Front Lip from ****** - cracked very easy

[JayKay335i]

You payed 30 pounds for silver coated blinkers? Hell, that would be rip off in US $.

[samchoi604]

Best mod:
window tint! Makes the car look much more aggressive from behind.

Worst mod:
a $15 phone holder I bought.. it's trash now because it never stays in place

[r0w3r]

Yup. The bulbs in the LCI E90 are not available anywhere else than BMW - the standard orange ones are expensive enough! I think they are PSY21W bulbs or something...

[leeadam]

maybe rear lip on my 330 sport..also rear valance painted...

Best:

DIY Plasti-Dip Matte Black Kidney Grills - $0 ($7 if you don't already have a can of Plasti-Dip)

I took my time with it and put on 4-5 layers with minimal overlap and 30 minutes in between each layer and it turned out beautifully.. best bang for the buck IMO

[BMWjames]

Best: ACS roof spoiler(rep) or tint

[CJ_LO]

worst mod - the jbspeed trunk i brought .. beside it's good fitment .. the shape does not look sharp enough (compare to the other csl trunks)

ps. ppl dont cheap out!!

[Ovalcram]

Best mod for me is CF wrap from PYSPEED

[samwoo2go]

Best:
Aero Lip (Free)
Matte Black kidney (Free)
Painted side reflector (Free)
BMS intake (Free)

Worst:
POS Tial BOV that kept on slipping off on me. (minimal lost since I bought used and sold it)

[TurboBimmer]

Best and worst in the same time: M5 SMG shift knob.

Best because it looks and feels awesome and is a huge improvement over the bulky stock shift knob.

Worst because it cost 300 EUR in parts and cables. And since my car doesn't have an ashtray I had to pay my dealer 300 EUR to get power cables routed under the shift boot. Making it a 600 EUR shift knob

[Tiz113]

Painted side reflectors
Black grille
Tints!

[T7R_Sky]

Best: KWV3's. Awesome handling
Worst: H&R Sways. I got raped with install fees :/

[E92-Lighting]

matte black grilles for being aggressive

[raceyBMW]

Best: My wheels, I love em!
Worst: My painted side reflectors, they don't match my paint (Jet Black) and I just don't feel like spending another $60 (from **********s)

[Mike@F1 Autohaüs]

Best value = DIY blackout grille and silvervisions ($5)

Worst value = LED angel eyes that give off errors messages even when they're advertised "error free" ($100+ down the drain)

lol that's a slick plug in there Mike!

[Brey335i]

Worst: Dinan Stage III Software that requires the Dinan Oil Cooler and Dinan Intercooler... ridiculous amount of money for the power you get back

[twinship]

Best: golf tee mod (actually a medical hose clamp, same effect)
Best: OEM alum pedals. Look great and feel good under my feet every time I drive.
Worst: License plate frame painted factory JB from JLevi. $45 I think. The $10 Pep Boys frame would have done the job...
