^ A number have done this, for the reason obtaining longer M10 studs to suit alloys (typically +15mm) can also be problematic. Spacers for S600/800 are also available with both M12 studs, and a more viable PCD to assist as well. Especially as they bolt up with OEM hardware, and then present a 114.3PCD at M12. If you do not mind the concept of spacers, then its a good option. I was lucky to be able and source M10 +15mm studs, and matching RS Watanabe M10 nuts (though not in black)...
Today I wired in a loom extension from the accessory feed for radio / MP3 player, and 12V-to-USB power adapter for telephone navi charging. Though the radio was only half sized DIN deep, with the wires for the 12V outlet, the radio antenna feed, and the MP3 to FM modulator, it was a tight fit getting it all into the center console. Lucky there is also a little extra space in front of the main console space, which is where the MP3 to FM modulator went.
A few months ago, I bought a semi-matching driving light switch for \500 (far right on switch panel), and it was installed to turn the MP3 FM modulator on and off. Turned on it blanks out the FM antenna feed and stops interference with the incoming FM radio signal. While the style radio does not really suit the car, its all black simplicity provides simple mono radio and MP3 for those stuck-in-traffic needs. Quite happy with the overall look and results, especially as the single speaker sounds reasonable when installed into the larger housing of the center console, and I did not need to take up any more interior space with stand-alone speakers. I was also surprised just how easy the DIN-style radio (as opposed to a shaft-mount) installed in the S; rear space & wiring issues aside, it was a breeze with the center console and body frame mounting-up as if it was designed that way. Not bad for a mere \2500 investment.
The manual-wind aircraft clock will have to wait for another day, as it required further cutting of the console panel to the rear of the ashtray, not visible, but I could not take the Dremmel to it quite yet. Pity, as I would have preferred to have it installed over the radio, not least of which is because it has a 12 minute stop watch timer, keeps perfect analog time on one wind for eight days, and just looks so damn sexy... I will however see if I can source a totally hacked up console, and use that. Neko.
