Hello Team,

Picked up another 87 NA over the weekend, and looking at the option codes, I can't seem to find what BT6 and C67 mean. They are the first 2 listed on my sticker.

Here's the full list:

BT6 - ?
C67 - ?
018 - Leather/Raised Hub 380mm Steering Wheel
154 - Control Unit for Improved Emissions---- What is that?
404 - Stabilizer Bars F/R--- Don't they all have that?
454 - Auto Speet Control--- What is that?
474 - Sport Shock Absorbers - Koni's?
650 - Electronic Sun Roof
946 - Partial Leather Seats Front--- I also see powered Passenger Seat

Thanks in advance... This is gonna be a fun one.

Never seen these before

not all cars have 404 OR 456 OR 474. You have the smaller diameter front and rear sway bars but also the sport shocks and sport springs upgrade. On earlier series 1 cars the code was 456 for Koni Sport Shocks but this was changed and the sport shocks ARE different between the two series.

Auto speed control is the Cruise control. Which may or may not be working or even on your car at present. Many by this time are goners.

What Don said.

C67...more likely C02 [US emissions]
404...sway bars f/r [23mm/14mm]
474...sport dampers f/r [Koni, adjustable for rebound]
