Since I'm new to Mini... I was wondering what are some good spare parts to have for the M03? Like which part tends to break more often?
Steering knuckle: I'm new to Mini also (M05). After my first outing (3 weeks ago) I needed to replace the front steering knuckle. It became deformed in a crash. I decided to go with the alloy knuckles for the front and the rear.
Body posts: I like to cut my body post to the proper length for the body I'm using. So, I can never have enough body posts of differing lengths.
Rims: Last, the lip of one of my rims cracked.
I was told that the Suzuki rims are strongest. If you haven't already mounted your tires, you may want to look for a set of the Suzuki rims.
