Is the supposedly upcoming .75" height adjustment feature on CGT designed for a permanent change of set-up or is height variable at touch of button? If set-up is permanent, should be interesting to see how much height affects track times. Also, what are comparable track times for latest version of GT2 and TTS w/X73 and X75? I suspect track time gaps between GT2/TTS and a raised CGT are fairly underwhelming... ...but those clever marketing people at P will probably mysteriously have difficulty finding copies of these cars for someone to independently document the performance gaps within the lineup
