Nice mate cheers for that,mine is a 5 spd auto coupe and seems you can see at least a second off 0/100 times and definately sharpen up the response , im trying to just improve it all round.... snappier, better handling and braking, traction etc... probably run the 18" rays 350z wheels for extra rubber and possibly the Z's Tokico shocks and springs.... 5 grand max all round and noticeable results with complete reliability and then focus on the more stupid and less used ride in the garage.
Does seem that most info and parts availability knowledge for these cars is ex US and seems we are about to see another dollar rate to our benefit soon.
