Just bought a 2013 G37S manual! So far so good, just unusually clunky 1st to 2nd shift but the rest of the gears are ok. Doesn't feel like a synchro issue, just clunky - anyone else have this issue? Also road noise terrible vs. standard G37 journey - thinking seriously about gluing in some carpet pad in trunk area.... Clutch is heavy but I'm buying the softer clutch pedal spring to address. Any other relatively easy and cheap mods you can recommend? Glad to know there is a group here! Thanks.
