Guys, there's only one man for the job, ibinco.
PLUG AND PLAY M3 PADDLES €160 SHIPPED http://www.e90post.com/forums/showthread.php?t=694525
I bought these and they are plug and play. No need to remove the steering wheel. Just need to remove airbag and the steering wheel trim.
As said my previous paddles were an awful design. These are left pull downshift and right pull upshift.
Now get ordering!
