ballpark figure howlong should they last? im at 67k an been luggin around 20's for 50k of that with the stage 2+ cobb a/port mods..ztube 3/8 plenum spacer test pipes and true-dual seems to be hangin in there?
i know its aquestion of the driver and if he/she abuses it, but gimme some of your info on when or if you have replaced the clutch yet...
I know they are noisy *** hell thats kinna scary ..

ok whos got the most miles on their clutch

stock clutch lasted till around 50k miles, i did shorten its life by doing donuts and burnouts.

replaced it with JWT Clutch/Flywheel combo which only lasted me till about 60K miles.

my mom and i both drive the car so two different driving styles probably helped wear it out faster. sucks though i thought it would last longer and take the abuse better than the stock clutch... guess i was wrong... i may have a defective clutch though. ill be sending it into JWT next week for them to see if it is indeed defective

im pretty easy on them well, when u can be waiting stopped i keep it out
or dont downrev unless i double clutch.

92K and still going strong on factory clutch before I totaled my g35.

95000km and still going!

Currently have 63K on mine beating the living **** out of it at least a few times a week. Plenty of passes at the track, encounters on the "Mexican Mile" (lol), as well as burnouts and donuts lol. I think the hydraulics might be giving me some issues on and off, but nothing crazy. Clutch still grabs good.

My friend has an 04 coupe with 90k on it stock clutch never been changed and still perfect but he doesn't abuse it tho.

i am getting a 04 g35 coupe from my friend at this weekend
he has 137k miles and still has original clutch. i will keep you update when it is really goes out

95k and still running the factory clutch!!!

It helps if you know how to drive.

i replaced my clutch at 64k miles. but i got it with 60k. and it was already worn out when i got it. it still worked, but im not the type of person that likes leaving things to chance. anyways, i replaced my clutch with a z1 motorsports mild performance clutch and it's great!

I have 80k on mine and sadly it's starting to show wear

140K miles and still on the stock. Going strong.

My clutch is going on 53K miles, and it's still good.

first clutch was a 800 miles! with a brand new G. Clutch pedle would stick to the floor ..
and about 10k on every other clutch up until i put the ACT clutch and light flywheel in it, no problems yet
