AKG Transmission Mounts. Flex Disc Questions

[John@Revshift]

It's not a solid guibo. It has polyurethane bushings which provide a proper amount of flex. There are tons of people with them installed on their cars. It's a proven part. No debate/discussion necessary.

This is from the description of your mount:
"For BMW e30 (318 323 and 325 only), e36 (318 323 325 328 M3) and e46 (323 325 328 330 M3), Z3 and Z4"

M3 only came with ZF so it should be good.

I would say the RevShift guibo is more for abused cars for track to handle excessive power. OEM guibo should do just fine.

I wouldn't install a RevShift guibo on any car. The guibo is designed to flex for a reason, because your car also flexes so the driveshaft needs to have flexibility.

Installing a RevShift guibo deflects vibration and required flexibility to the u-joints, transmission mounts, and engine which will eventually destroy said u-joints and mounts.

The only thing I would install a solid guibo or driveshaft into would be a drag car that races in straight lines.

i measured mine and the rubber part is 32mm (1-1/4") high. if yours is the same it will be fine.

if it's good for the e30 325 and e36 M3 then it should work with s50/52+zf in e30 chassis. the only thing i can think of is the height of it that might be a problem. if you could measure it i can compare it to the one that's used for this swap (e21 i think). i have a brand new one.

Just oem.

Proven race cars, 600+ hp bmws, and established tuners with the likes of Turner Motorsports, and Bimmerworld all use OEM guibos in their race car drive lines.

Oh good to know. Thanks!

Right, but since the tranny is going into an e30 chassis, I didn't know if it would still work. But if that same part fits alla those applications then I guess it really shouldn't matter. Thanks.

I have these on my car currently, but will they work with the E36 M3 ZF tranny?

Also, for a daily driven, 90% street car, would you recommend a Revshift guibo/flex disc or just OEM?

Thanks.
