    Thumbs up BMW N54 135i / 335i HPF CLUTCH INSTALLATION TECH VIDEO by HorsepowerFreaks

    We often do tech videos to help the community with installations for various parts. The GT1 tool and All Data are helpful for many types of installs but don't often have enough information to help you through the entire installation. This is especially true for late model vehicles.
    So here's a video we put together that will help any backyard mechanic swap out their clutch in a BMW 135i, 335i and even the 535i.
    Here's a link to our new HPF BMW N54 clutch. Click here to enlarge

    yesterday I think I felt my clutch slip testing the cobb race map 21psi down low on 2 occasions but not sure yet, may have been tire spin in 3rd gear at 60mph...didn't happen after...might be looking into this clutch next if it does turn out to be the case but my ACT was really reliable for 40,000km now with all the hell i put it through in the last 8 months...

    Chris what clutch do you recommend in my case, car's currently putting down around 500whp about the same torque but might be seeing a bit more soon, less than 600whp/600wtq for sure...how does your clutch compare to the ACT organic which has held up really really well to my street driving and some drag strip fun...ACT rates this clutch for 440ft-lbs but its held up to a bit more than that for a while now...

    FYI, my clutch masters fx400 with their lightweight flywheel lasted 2,000km on the car after which it was warrantied by CM...my original stock clutch lasted 75,000km

    ACT has been holding well. The ratings are always lower than what the clutch is capable of. However, it is a good practice to go with a rating higher than the actual torque. Clutch ratings are typically crank figures, so you are way over the the ACT rating. I believe HPF has good alternatives. Where do they engage? I'd prefer engaging at the stock engagement point and the use of the clutch stop sold by BMS to keep the travel down.

    Let's shoot for something that holds say 700wtq, should be plenty for a while and doesn't die after 1k miles Click here to enlarge

    You aren't getting very many miles out of those clutches. I definitely recommend the HPF Feramic clutch. You won't believe how smooth it engages. It drives exactly like a factory clutch but will hold in excess of 700ft-lbs. We just ran the same clutch in the HPF M3 at over 1,015rwhp for 50 dyno pulls and some racing. We also run the same material in every E46 M3 turbo kit and have been selling them for years to high hp Supras. It's hard to believe a clutch this smooth can hold so much power. I recommend getting another factory flywheel or surfacing the one you have because it is probably not square anymore and you may ruin any new clutch. This clutch will last you a long time.

    Normally you don't want to go with a clutch that is overrated because in order to hold the power you typically get a grabbier clutch disk and a greater pedal effort. The pedal effort on this clutch is about 25% stiffer which feels perfect and the engagement is butter like smooth. Click here to enlarge

    My ACT is still holding no slipping I guess it was just wheel spin the other day...did about 15 passes last night on it last night 1.77 1.85 60' no issues and tons of 60-130 runs and 1-4 gear pulls...I'll see when it does give out and I'll definitely keep this in mind...thanks Chris
