Joined up a little bit ago so thought I'd finally say hello.
Got my E82 135i LCI early last year, this is my first BMW and absolutely love the thing.
It came with a performance exhaust, endcc front lip and Breyton race GTS-R wheels.
In the time I've had I've added a Wagner intercooler, FTP intercooler piping, MHD stage 1+ tune and M3 front arms, will look at maybe doing the rear arms and subframe bushes at a later stage. Really happy with the performance.
Interior wise I've wrapped some of the trim in alcantara and swapped out the center trim for 1M pieces. Also changed out to some Nelson Racing Wheel paddle adapters with Pedal Haus paddles, much nicer feel over the factory paddles.
Audio wise I came across an E82 at zebra that had some plug n play focal front speakers and Rockford fostgate rear speakers, sub wise I chucked in some logic7 subs, cheap and cheerful sound upgrade until I can afford to put in an amp.
Maintenance wise changed the troublesome oil filter housing gaskets and got pedantic with the water pump/thermostat and changed those. Next up to look at a weepy gearbox sump ?
