At the time of publishing this video, we have recently been featured on Motor Trend TV or Discovery's Wheeler Dealers - assisting with their conversion. We've also been featured in Grassroots Motorsports. Again, at the time of publishing we've completed 10 E46 M3 SMG to Manual Conversions this year alone.

Along with the full conversion, we offer a bellhousing prep service for clients and shops attempting the conversion themselves. At the time of publishing, we've had 34 Bellhousings prepped for other team's conversions this year.

Some reviews for the conversion:

Steve F. on Yelp - "When a shop has E46 M3's lined up, and a dog, and a lathe and mill, and is orderly and quiet-- well, that gives me the warm fuzzies.

That contrasts with the feelings I developed after a few years of using a shop closer to home in LA area.

I recently picked up my car from Lang following the (monumental) SMG to manual swap. I'm only aware of one other place in southern California that has done LOTS of this project, so finding the right shop for this is important. Jonathan, the guy who answered when I first called, was informed and responsive and got all of my questions (as a fussy prospective customer) answered quickly and to my satisfaction. When picking the car up, it was also nice to get to talk to the guy who'd just completed his part of the project (he proved very knowledgeable).

I'd like to point out that the SMG swap is a very big project and there are a lot of ways it could be messed up (cruise control, etc). Lang has it down, and my conversion went off without a hitch.They estimated a week for completion and mine was done on time and without cost overruns. Everything works perfectly.

A couple things I really appreciated:
1) No BS. I asked the owner a technical question that he didn't know the answer to, and instead of making something up, he said "I'm not sure, but hold on and I'll find out" and went and got an answer from the guy who knew the correct answer.
2) No "there are lots of things going on so we'll get to you when we can" attitude with my business.

For those into the E46 M3 for the long haul, his place is definitely worth checking out. I live about a hundred miles north, and these guys will have my business from now on."
