Hi All,

Quick background - 2007 G35S sedan w/ 65k miles. I went into the dealership after noticing my clutch reservoir was empty (previous thread). I hadn't seen evidence of a leak but couldn't get underneath so I went in for an oil change and inspection. They said there is no sign of a leak but that my clutch is worn and needs to be replaced soon

An OEM clutch is $1000 (without flywheel) and since it's been our only complaint of the car in 5 years of ownership, I think it's time to go aftermarket.

I started reading the forums before posting and a lot of folks are going lightweight, performance, etc... My wife (it's her G) has always been jealous of my Audi and BMW transmissions because they're smooth and not touchy - what would you recommend for the Infiniti that is a nice daily driver clutch since it's a stock car?

EDIT: I just read that this car might have a helper spring, sort of like how the 3-series 'had' (I removed) a clutch delay valve. That might be the cause of our complaint for "smooth" more than the clutch itself?

 

Of the few aftermarket clutch equipped G's I've driven, the problem with clutch feel appears to be more in the pedal setup than the clutch itself. It's just got a strange pivot point location. If anything, swapping to an aftermarket clutch (either lighter flywheel or stronger clutch for higher power builds) seems to make the feel even more vague. Keeping in mind I've only driven two or three that had aftermarket clutches, so this won't be true for everything, but the ones I drove felt worse than stock. Only slightly, but still.

Having said that it's not all doom and gloom. I would look at what clutches are going to meet your needs in terms of power and whether you want to go lighter on the flywheel, and then add the RJM adjustable fulcrum point pedal setup. I recently got mine and haven't had time to install it but the reviews I've seen have all been very positive. Apparently it allows you to change the pedal's feel completely and dial in the engagement point you want. That's probably your best bet for smoother operation, although there have been guys in the past that have pulled the spring and liked the feel that resulted. The RJM is more expensive, but it also gives you more flexibility and doesn't change the clutch operation, just the pedal feel of it.
