    Wheelhop Fixed ! 335i :.)

    Had my diff locked down last week. Car doesnt show any wheelhop from a dig, slides are much more stable in a drift as well. Lockdown kit mods were poly bushings to replace all stock diff bushes, movement limiters and an additional arm added to the rear opposite the single rear bush.

    Other goodies installed at the same time include the 335is motor mount and poly on the front upper thrust arms. Both noticeably improved car dynamics.

    Those of you in the Eastern Pennsylvania Region can visit my fabber's shop; located an hour outside of Philadelphia in Bucks County. Give Rick a text/call at 267-884-3025. He's looking for a 135i and a Coupe for kit verification.

    Was this a kit you installed or just bought M3 OEM parts?

    Everything was custom fabricated, ear & arm, poly bushings & bushing movement limiters.

    Good to know. I have some bad wheel hop at times and was planning on getting all of the M3 bushings and arms. Just didn't know if there was anything better. Glad you got yours sorted!

    Cool, I'll just need the arm..i've been actually looking into this last year...this is a very typical mod on american muscle cars where they add an arm coming down to the diff housing to prevent twist on launch...

    definitely interested in the "arm" part of the kit...whoever is making it should have a separate sale for that arm alone as many of us already firmed up the rear with m3 subframe bushings and m3 rear toe arms that almost eliminate wheelhop entirely...that "arm" will be the final piece of the puzzle to make it 100%

    good work man! keep me posted for sure when/if its released...

    This was a one-off fab and was done pretty economically. Rick wants to do a 135i and a 335i coupe before making a kit. If you're willing to take the jump you can give him a call at the number in the OP. Those willing to come out to the area will get a good deal on the kit Click here to enlarge

    Saw you did get the 335is motor mount. There was some contorversia whether or not these are different from the standard 335i mounts. Did you get a chance to compare them side by side? If so what is different exactly?

    Autobahn335i, I'm not sure what the differences are, but the P/Ns are different -only- for the passenger side (LHD, right.) Most of the difference is likely inside the mount. I noticed that the engine feels much more solid but I would likely feel an improvement if I put a new stock in as I'm at 90k miles. I think it's worthwhile to do an IS mount over stock when you're replacing your MMs due to maintenance. I managed to pick one up for around 250$ USD.

    +1 and throw some drifting into that. OH and get a fat guy to jump up and down on the trunk when you launch. If you can handle this then you have my money.

    Having no wheel hop on winter roads doesnt say much. 99.9 percent of the time on the street i wont hop. At the track though it more like 70/30 that it wont hop. Guys on slicks hell might as well order axles cause imo you got a 50/50 chance if you are a manual owner of breaking something.

    My 1M snapped a charge-pipe in half from wheel hop on concrete from a dig on the 1-2 shift.

    Is there any down-side to doing something like that? (The anti-hop mods)

    i think the official term for a diff lockdown bar is "axle snubber"...look them up! very popular on american muscle

    Here's some info from an article i found...i like their comment on the rear lower control arm, making it parallel with the ground and not lowering the car past that in order to eliminate wheel hop:

    The easiest and least expensive way to cure wheelhop in a rear-coil-spring car is to first lower the rear suspension until the lower control arm is level and parallel with the ground. That helps return the rear suspension to its proper geometry to help plant the rear tires. It may be difficult if you have large-diameter rear tires, but any effort toward positioning the lower control arms parallel with the ground will help.

    Yeah, it was really pissing me off, considering my 135i before never had an issue. That was my second one, replaced by dealer. And the first one would keep disconnecting from the throttle body. The dealer was starting to think that I was up to something.

    Third time was a charm, hasn't blown a apart or popped off yet. (Knock on wood)

    I'm guessing $#@!ty quality control, or bad manufacturing tolerances of the equipment.

    Did the dealer end up replacing your motor mounts the last time out? I just find it hard to believe the engine shook so damn much that you cracked your cp. Sure sounds like a loose or cracked mount to me.

    I mentioned that to them, that there may be some loose drive-train components causing the issue. I also get a slight "thud" as I let off the gas from light load at highway speeds, probably from the LSD. They said they checked the engine, tranny and diff mounts and that everything was fine, so hopefully they actually did. I'll check them with a torque wrench when I'm under the car putting on CP-E Mids and DPs.

    Anyway, if that guy could make a kit for us that would be really useful, especially with sticky tires at drag strips.
