Here are some pictures of my BMW Z4 coupe. It's a 3.0 litre SI in black sapphire with black leather interior.

Last year I fitted a 600w InPhase amplifier and 2x 10" subwoofers in the boot. The amplifier sits in the battery compartment, which is in the back in the Z4. The bass bin is a 25kg monster, it takes up about half of the boot.

The boot in the Z4 is separated from the cabin by a retractable screen. If you open this up, the woofers are firing just behind your ears. Which probably explins why I can't hear my wife unless she shouts at me.

The amp wasn't too difficult to fit, although I had to build a frame out of 18mm MDF to attach the sub to the chassis of the car - you can't see this in the pics because it's hidden behind the boot lining.

The rims I would like to win are Dotz Tupacs. My friends think I am mad wanting to mod the Z4, but I think the Tupacs would really finish the car off.

The tyres on the bimmer are Bridgestone run flats, which have been on since new (225/40 on the front and 255/35 on the rear). These tyres are so hard that driving down a normal road feels like riding a camel down a cobbled street. I would really like to try a set of the Marangoni tyres to see if this improves the ride quality and handling.

Hope you enjoyed the pics :)
