Hello. I have a 2004 g35 i just got all new syncos, resurfaced flywheel, new OEM clutch.. the shifting and pedal are silky smooth it feels great but i noticed in 3rd gear only accelerating 2500-3700 i feel vibrations.. is it the flywheel? Will it go away by wearing in? Should it go away by 1k miles? Or do you think the install was done wrong?Any help will be greatly appreciated. Thanks.

 

My question is where did you have the work done? If the flywheel is out of balance now it won't get better with time, there is no break in period! Since you didn't have the vibration before I'd take it back to the shop. Glad everything works well, almost....Gary

 

I got the work done by a local guy i know.. ive seen work he has done he is legit.. so if its not balaced wouldent i hear vibrations through all gears? Get it resurfaced again or have him check the flywheel? Is it bad to drive on it? He gave me a year Guarantee so i wont be charged for this. Thanks for the respond gary.

 

It might not be the flywheel...definitely go see him.
