OEM G35 Clutch Master Cylinder

Replaced a bunch of stuff while having a new Clutch and Flywheel installed. This item was a must for me as it's been on the car for 140,000 + miles.

OEM quality as expected

Awesome service and team. Thank you guys!

Works as expected. Perfect fit.

my pedal isn’t getting stuck to the ground anymore, great product no issues.

Installed along with a new slave cylinder and now my clutch feels better than ever!

Exactly what I needed. Works great unlike the autoparts store brand that I tried 2 of.

It dropped in issue free and i was able to bleed and clutch is working.

After 13 years with the original fluid, and having pedal problems when hot, it was time to replace the whole system except for the original metal line. I recommend replacing the master, slave and the original rubber insulated hoe with the stainless insulated hose. You may spend almost $200, but if you take it to the dealer, the labor bill would be at least $500 and with parts, $800. Also, before you do anything, flush the entire system with a cheaper DOT 4 than the Motul. The old fluid can be toxic to your new parts. And be sure to put the new master cylinder in a vise with the old reservoir and hose and "bench-bleed" the master cylinder (You Tube video). Attach the reservoir and hose to the new master cylinder while on the vise and install the master, hose and reservoir together in the car. You can bend the hose and reservoir to vertical to get to the fitting and screw it in. Same with removing the old master. Remove the reservoir and bend the whole thing vertical to remove the fitting. Reinstall the old firewall gasket on the new cylinder while on the vise as well.

Z1 has the best customer service iv ever had. I only buy from Z1 now!

Part number 30610-JK00B. I bought this product to install on a 2007 g35 S sedan. Yes, a sedan, not a coupe (big difference). Everything was perfect except that the studs on the new CMC are longer than the studs on the old CMC I took out of the car. I had to swap studs, because the longer studs made it impossible for me to get the angle I needed to get pass the holes on the fire. I tried for an hour to get the studs pass the holes in the fire wall. I was so confused, considering it's OEM. Then when I compared the studs...boom, problem found. Swap or cut the studs, and it'll fit the sedans fine.
