CG-Lock Install

I went to the BMW Club’s September Autocross event and while I was there I took a lap as a passenger in someone else’s car. When I got in and went to buckle up I found this strange attachment on the seatbelt and asked about it.

It was a CG Lock and after the driver showed me how to buckle up the benefit became immediately apparent: the CG Lock stops your lap belt from slackening or tightening. If it’s tight then you are firmly connected to the car and therefore more aware of what the car is doing.

I ordered one, installed it (it clamps on with only 2 small bolts) and tested it while driving around today: works great, feels good. We’ll see how it really performs at autocross tomorrow.

Update


The CG Lock was an excellent addition to my autocross set up and made me feel considerably more “connected”. However, by the end of the day the clamp that attaches the CG Lock to the belt buckle started becoming loose and the whole thing ended up in my glove box. I don’t feel comfortable using it for every day driving but I expect to use it again next time I autocross.
