Soarers have a black diagnostic port located under the bonnet on top of the engine. Pop the top open and don't be bothered if it appears to be full of white goo, it's there to protect against rust etc.
If you have any form of TEMS (electronically adjustable suspension), one of the diagnostic tests puts the suspension to it's firmest settings. We can exploit this setting to firm up the Soarer for track days, hooning or all the time for normal driving.
This modification has no effect on UZZ30's or TT's without TEMS.
