I ran my first AutoX today... amazing time.

The only thing was I was bumped to STS because of my rear sway bar (my only mod... booo.) Anyways, I was talking with some people about my recent Cooper S purchase and that it's comming with a LSD and I've already ordered the Wilwood BKK. No one was really sure if these were STX legal. Any experts?

 

The stock LSD or any LSD for that matter is STX legal. You can do a BBK for STX too. Actually, if you ever want to run DSP with race rubber, you can leave the BBK on as long as you are in full STX trim(8" wheels, no additional SP mods that are not STX legal like Flywheel/clutch 9" wheels etc).

 

Great. This might make me change my mind on the reduction pulley. Thanks for the info.
