ST Coilovers Spring part number?

I recently bought and installed a new set of ST Coilovers on my 2012 135i. I had them done at a local shop that specialized in BMWs and had installed countless coilovers.

For some reason (even at the lowest setting), they cannot get my tires to tuck under the rear fenders. There is still over an inch of a gap between the fender and tires. They had double checked everything and I confirmed with them that the old spring cap at the top was removed.

My B measurement (distance from center of wheel cap to fender) is 13 inches.

I think I may have received the wrong pair of rear springs. My spring part number is "2012 30E12". Can someone with ST Coilovers check their rear spring number so I can verify that I did indeed receive the right ones?


Thanks

Would really appreciate it if someone with STs can help me out. Just jack up the car and look for the number. Takes 2 minutes!

I spoke with KW/ST a month ago and they confirmed that the parts I received are indeed correct and that that is the lowest the rear fenders can go. If you measure from the center of your wheel cap to the fender edge, the minimum distance you can get with ST coilovers is 12.8 inches (both front and rear axles).

What confused me though is that I can go much lower than 12.8 inches in the front. I'm currently at 12.0 inches in the front B measurement and I'm only at half way on the spring height adjuster.

Rears are at the lowest setting and fronts are about half way. The first picture is a closeup of the rear left wheel.
