Check them out behind the old Bavaria BMW location. They are sandwiched between a Sobey's corporate office and the old Bavaria BMW used vehicle building.
I have known Theo over at Karmac for about 8 years. He is the only one who does the mod installs for me on all the BMW's I have owned. Knows his stiuff, doesn't BS you on price, and never had a problem with anything they have done.
I have had all my mods shipped to them and when my e92 arrives it is going there for installation of all the parts, including the possible Dinan springs.
