    Thumbs up HPF Stage 2 Feramic Clutch Kit Quick Review

    Are your revs going up then down while on WOT? Well it looks like you may have clutch slipping problems. For a whopping $1200, you can get your problems solved with an HPF Stage 2 Feramic Clutch Kit!

    Pedal Feel
    000-100 miles: ~2.00x stiffer
    200-500 miles: ~1.50x stiffer
    > 1000 miles: ~1.25 stiffer

    I got brand new OEM Release Bearing Assembly with the clutch. Initially, the pedal was pretty stiff, about 8 out of 10 being the stiffest. After 1000 miles, it got noticeably softer. I would say its marginally stiffer than stock after broken in 1K miles.

    Full Clutch Engagement
    000-100 miles: ~1.00" deeper/lower than stock
    200-500 miles: ~0.75" deeper/lower than stock
    > 1000 miles: ~0.25" deeper/lower than stock

    Initially, the clutch engagement was really low. It felt like it was right off the ground. But as the miles racked up, the engagement got higher and higher and closer to stock. Like everyone says, it's a tiny bit lower than stock.

    Partial Engagement First Gear Shudder
    000-100 miles: lots of shudder
    200-500 miles: less of shudder
    > 1000 miles: no shudder!

    This is what worried me the most after installation. Well, also trying to get used to an initial stiff clutch didn't help but the clutch did chatter on 1st gear. To alleviate this initial problem, I ended up putting more throttle than usual and releasing the clutch pedal faster.

    It almost seems like I was trying to slow launch the car all the time. Over time, the shudder got less and less and now that I'm around 1200 miles, it's really not a problem anymore, even when I release the clutch slowly without any throttle.

    All of this talk but did it solve the slipping problem?
    Of course it did! I've done multiple E50 logs and there is no problem with the clutch at all. Actually the clutch feels great and seems really eager in the gears.

    The Verdict
    + Future proof for RB S2 turbos or VT S2/S3 turbos
    + Solves clutch slip problems
    + Engagement is really close to stock
    + Daily drivable
    + Shudder eventually disappears
    - Price is on the high side
    - Shop installation cost
    - Top Ramen for lunch

    ahh thank god the shudder gets better.... i have 115 miles approximately on my stg 2 clutch and it shutters like crazy...
    hpf recomended to slowly release the clutch from 6k rpms and i have been doing that a few times to relieve the car from the shudder and it helps temporarily.
    great write up!

    hpf said that after 100 miles you can apply full power and after 300 you can do hard launches!

    I've had 450 miles on my HPF and the chatter is reducing. When it was first installed my heart sank at the amount of chatter and judder. The car feels so much better and quicker without having to deal with the clutch slipping all the time.

    Mine shuddered like crazy, after 300 miles i hit the track and did a few launches on street tires and its been golden every since. Gotta treat her like Rihanna every once in awhile.

    Nice writeup. Did you resurface your stock flywheel?

    I was told I could throw my car on the dyno right after install (like they do with their Staged E46 M3s).

    Never had shutter, engagement was like stock, and the pedal felt stiffer all the time.

    I put it on my stock flywheel without resurfacing too... Click here to enlarge

    The shop said the fly wheel can't be resurfaced but they did clean it up with clay. They called it manual resurfacing.
