Nice spoilers! I like the upper hatch one. I would put one on mine if I had wider wheels. Locally, there is a set of style 63 Tiger Claws for $300. Unfortunately, I have new tires on mine. It will be 50-60k before I need another set.

Are the spoilers paint matched? Post pictures after installation.

I think oil consumption on mine is down to whatever the M54 design would use. OFG, VCG, oil pan, and updated cold weather CCV have reduced bad oil consumption. Mine did smoke at start up and hard accelerations when I bought it. After fixing leaks and updated maintenance, I don't carry a quart of oil anymore. I even went to 5-40wt oil. The heavier weight oil is better for summer. I drive it slow until it's up to temp on cold days.
