BigJames 15 Report post Posted July 16, 2015 So I've only had my GT86 for a little over a week, and have done just over 500 miles. I'm curious as to whether I have an issue or if it is just a design "feature" that is the same on all ZN6s. When changing gear and being a little quick to lift off the clutch pedal there is a feint clunk from the back of the car, like the car has bad diff mounts. Is this to be expected, and should I just order some Whiteline or similar upgraded bushes? I might be wrong on the location, but it seems like when the diff is loaded up there is definite movement, even at just 4000rpm... Share this post Link to post Share on other sites
Church 209 Report post Posted July 16, 2015 Same on mine. And even on simple 1st gear engage on stationary car with fully disengaged clutch. I believe it's diff loading. Never had car before with LSD, so it made me nervous a bit at first, but now i'm used to it, simply ignoring it. It even subjectively makes feel like something sporty/more mechanically direct, without all hushing down for comfortness and quietness sake, even if this sound is way different from something some sport sequential straight cut gears gearbox makes.

Ade 517 Report post Posted July 16, 2015 Yeah its classic LSD clunk. I kinda like it. Makes the car seem a bit more mechanical and because RACECAR... 3 Polishingpedlar, Mike and Minion reacted to this Share this post Link to post Share on other sites
Guest Report post Posted July 16, 2015 I don't believe it has anything to do with the diff itself, but more than likely the VERY soft diff bushes, VERY soft rear trans mount or the VERY soft propshaft centre bearing mount.I don't think Torsen LSD's clunk anyway.If you fit whiteline diff bushes you will experience an increase in NVH. It is in fact much like engaging drive in an old automatic when you put the car in gear stationary. Share this post Link to post Share on other sites
