2024 BMW i4 eDrive40 — question: Engine swap packaging: offset versus driveline angle

V8Traveler86Community StarterJun 10, 20262024 BMW i4 eDrive40North Jersey
Mocking up an engine/transmission in a chassis with very tight steering and footwell clearance. I can offset it slightly, but I don't want to create driveline vibration. What measurements should be locked down before making mounts? Any data points from owners would help. What am I missing?

I parked the 2024 BMW i4 and wrote down what I already tested so I'm not repeating myself. This is the version I'd tell a friend.

Don't overfit one forum story to your car. If it still isn't clear on the 2024 BMW i4, a specialist hour can be cheaper than another round of parts. I'd do that before spending real money. Do that first. I'm in no rush to be a hero on it.

Write down what you already tried. A second data point from another 2024 BMW i4 owner helps more than a generic diagnosis. That's where I'd start. Take it or leave it — that's what I'd do. Might be overthinking it, but I'd rather overthink than overspend.

Owner notes beat generic advice here. On the 2024 BMW i4 in North Jersey, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “question: engine swap packaging: offset versus driveline,” that was the fork that mattered for me. This is from a 2024 BMW i4 in North Jersey. Just my two cents from doing this recently. This is the filter I use when the thread starts repeating itself. Wrote this up on my lunch break.

That's my plan before I call anyone.

This is from a 2024 BMW i4 in North Jersey. Do that first. That's coming from doing this as an owner, not a shop. I'm keeping receipts and dates in one folder.

I'd keep this practical. Verify the cheap/easy branch on the 2024 BMW i4 before a big repair or a big spend. That's where I'd start. This is from a 2024 BMW i4 in North Jersey. That's the whole play. This is me being the wet blanket on purpose.
