Fixed Grinds and Low Bite Point
★ ★ ★ ★
Michael | July 28th, 2026
2007 civic si sedan. I just installed and have driven about 30 miles, paired with a ktuned slave cylinder. I don’t know what clutch the previous owner put in my car but it’s very heavy. The stock / em2 style cmc was not strong enough to fully open my clutch. Previous symptoms included constant grinds, shudder / creep when in gear clutch down, getting stuck in gear, clunks shifting gears, all caused by clutch dragging not releasing fully after install on this kit, my clutch starts to drag ab 1” off the floor, and bites hard around half way pedal travel. it feels very heavy now, but bite point is absolutely perfect / like a normal clutch again. i did not have to trim the threaded rod, i backed the cmc itself out a couple turns on the plate. if the bite point gets any higher i will have to trim the rod for further adjustment Ialso had to use both pieces of the clutch line, due to the outlet being 90°. if the kit had included a double sided 3an elbow, i could’ve used just the one piece of the line. if you install to one of these 8 gen civics, angle the clutch out line to the left side / 9 o clock position. otherwise the angled line will get stuck on the firewall and prevent installation / could get the cmc stuck back there for 30 minutes im super happy right now, my next step was drop the transmission and i did not want to do that. idk what clutch i have but it feels very heavy, the feel is heavier now with this kit installed. i was able to put the reservoir at a slight angle in the stock spot, using the stock bolt and a spacer if i rated this 4 stars it’s because they didn’t include a 90° elbow. everything else has been great and feels quality 5 stars otherwise
