Hi HPA members!

Figured I'd put up my current build thread now that I'm officially a member of the community. Here it goes:

Car is a 2010 135i Automatic, with N54 engine.

I've done almost all the needed maintenance since purchasing the car at 76k from the original owner. With the exception of the injectors and HPFP.

I'm currently waiting on the JRZ RS1 Coilovers to arrive (450/700 spring rates). When they do, I'll be installing the M3 front control arms, SPL rear upper camber arms, Rogue Engineering rear toe arms, and Condor rear subframe bushings. While doing all that I may install a Wavetrac helical LSD.

Just finished putting on the painted Seibon carbon hood and trunk.

Car is sitting on Apex ARC-8 wheels; 18x8.5 +45, 18x9.5 +58 with Indy 500 tires.

I'm currently working on troubleshooting an issue with the Flex Fuel components, and will be looking through this forum for some information to help guide my testing.

agreed, awesome to see more N54 cars.

nice build as well.

Nice work!

Great to see some BMW builds on here.

I just picked up a haul of parts for my E90 320i - it will be a slow migration to the track as it approaches road-retirement. Probably not that interesting for anyone here at the moment, but may be worth starting a little build thread to keep track of things over time.

Looking forward to the updates on your build.
