Description:

2002 Underground

Our passion is pushing the boundaries and possibilities of bolt on performance parts for BMW 2002s.  

2002 Underground exists to address the weak points in the drivetrain when more horsepower and torque are added.

 

 

Our flagship product is the custom rear Subframe built from scratch to fit the BMW 2002 and equip it with a BMW e30 medium case “188” differential. This is an all-new Subframe supplied with new custom halfshafts and built in toe and camber adjustments.  We were the first to introduce this product in small production runs to the BMW 2002 community in January of 2011 on the FAQ website.

Shipping and PayPal fees are included in the lower 48 states.

If you are looking to use the stock or e21 differential, I would think you could find a good used rear subframe.  If you want to go with a e30 medium case differential, we would be happy to help.
