"Custom" axles 🤔
Engine sits 35mm closer to the firewall and 9mm closer to the passenger side.
Thinking it through, this requires custom axles.
The passenger side axle was 12.5mm short (track width of donor vehicle CRX ED9 is 25mm narrower than the track width of the EJ1), closing that gap by 9mm by engine re-positioning sounded okay. Tested it, assembled the drive shaft, done ✅
Thinking again, the driver side axle, being 12.5mm short, should become more of an issue, as that gap is widened to 21.5mm.
Test-fitted a longer CR-V axle (CR-V driver side, 21mm longer, joints fit on there), which blocked at the lowest position.
(The lowest position is below full droop, only reached if the coilover is taken out. In theory not relevant on track, but... I was looking for a solution, not a compromise)
So, testing continued with the old ED9 drive shaft, which in theory is too short -- but practically seems fine, same as on the passenger side. So, I'll try this setup: shifted engine position, keeping the same axles left & right 🤷🏽♂️
My learning: all that thinking didn't get me where I wanted to be. Test-fitting and measuring did. Fingers crossed this setup works 🤞🏽
