Aftermarket Flex disc/Guibo from Revshift....preliminary review...
So after that Bear Mountain Run on Memorial day weekend, I realized that after all the mods The new power on 57k old Flex Disc (aka: guibo) did not go over smoothly.....it gave out, so at low speed accelerations i get the vibrations.....badly.
I went searching....found something that replaces the oem F/D on the Drive shaft......I ordered it. I will be installing it in the morning.... It looks serious... I made a review of some sort.... |

Normally, this disc would add some NVH, but I see you're already running urethane motor mounts and trans mounts, so this will be a sweet addition.

I have heard about the guibo cracking on M3s but after buying one a while back the OEM piece seems pretty serious. It makes me wonder if you hanger bearing failure may have caused the guibo to crack. While the changes you made it seems would prevent any type of failures I have to wonder what it might do to other things in the case of a failure.

^incorrect, by pure namesake alone one can predict that limits over the Driveshaft bearing will be pushed to the max as soon as the "flex" disc over "flexes" from more torque than it was designed for.
I mean they didnt name the driveshaft the "flex driveshaft" they named the "flex" disc a flex disc because thats what it does....it flexes...as soon as I added headers everything went weak for the guibo (flex disc) ....So that's where rev shift comes in....no flex just go.....I just finished ripping through all the gears with dsc off on the Queensborough Bridge with no problems....I intend to drive this thing into the ground only to build it stronger. I seriously suggest this mod to ANYONE dropping their exhaust to ddo any work ie; headers, clutch work, ssk, etc.... Revshift Replaces doubt with Polyurethane..... :-) |

That sucks. It can't be the extra power from headers/etc. as I haven't seen any of our supercharged folks breaking it, maybe something else is going on.
