I would like to know which of the two trannys is geared lower, the ZF or the Gtrag... Meaning that if you left your rear end the same which tranny would run at lower RPM's? Next question is about drive shafts and Flywheels... If you get a ZF do you need the driveshaft that corresponds to it or can you run a Ti drive shaft, also if it is a ZF does it have to run the flywheel from the 6 or does it have to run our 4 cyl one? Just trying to figure out what would be best for my Auto to Manual swap... Thanks in advanced guys! Any and All information is greatly appreciated. __________________ 2LT Rodriguez CA ARNG TURBO 96' Sport, Alaska Blue, Auto Custom JohnBoy Turbo, Midnight-Tunning Software, HKS BOV, e-Pod Gauge Pod, BavAuto Springs, Bilstein Sport, e30 3.73 LSD, Depo P36, Apexcone 55w HID, OEM Spoiler, M3 Lip, M3 Mesh Grill, Crossdrilled Rear Rotors, M3 Front Brakes, Sparco 3 point Harness, Euro M3 Wheel, K&N cone, Clear Corner/Sides/Tails, M3 Center Console & Arm-rest, M3 Red Cluster Needles, M3 Mirrors & Side Skirts, RD Exhaust, DS-1 wheels!... | | | 04-02-2009, 05:19 AM | #2 | Senior Member Join Date: Apr 2007 Location: Elizabeth City, NC Posts: 3,877 | These are the gear ratios I have for the ZF and getrag. They are pretty much the same. Definitely needs an overdrive. Check out the getrag 260 if you want lower gearing, there is a thread on bimmerforums about what you have to do to swap it to an E36.

Additionally, does the shifter rod length change? Thanks!

With a ZF you'll definitely need the front half of a 328/M3 driveshaft and balance it with the ti rear half. I think if you have a 198mm selector rod already that it should work with the ZF. UUC/AKG list the same selector rod for late 325i and 328i/M3. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 07-30-2017, 03:14 PM | #6 | Senior Member Join Date: Feb 2012 Location: Sacramento, CA Posts: 2,451 | Thanks Dave. On my way to the yards to source the front half of a driveshaft. My UUC rod went it yesterday and renewed all bushings. No sloppiness now. Smooth with the right shift point notch.

None here locally. Anywhere... yards, dismantlers, reman or new. I ended up sourcing one from L.A. To install on Thursday.

I did source a front driveshaft from L.A. And got it all installed last week. It performed well on the track and I feel more assured with the larger flex disc.
