Roadster Gearbox Mount not Centred

[Jethrow]

Hello all.

Whilst trial fitting the trans in my roadster, I notice that the gearbox support frame is fabricated such that the gearbox sits off the centreline at the rear. Why is this?

I know the drivetrain has been offset to the right for better weight distribution, so is this just part of that, or is there another reason the gearbox tail shaft is not on the centreline?

Thanks

Hi,

The primary reason that the engine and transmission is offset to the passengers side, is to give a little more drivers foot box room. That way the accelerator pedal is not as close to the brake pedal.

FYI, the stock Mustang (at least the '04 and older) were setup this way as well for steering shaft clearance. You can really see it when you look at an aftermarket tubular K-member and the mount bracket differences...

Also the input flange on the rear axle is offset to the passenger side, so having the Engine/Trans offset give better balance with just a driver, more pedal room, and lines up the driveshaft straighter with the axle.

Thanks for the replies everyone.

I just needed to understand this better as I do my RHD conversion. I think I am going to put everything right down the middle so I can make more room for the RHS footbox as this will be the drivers side.

Tim,

The headers are different side to side in an Mk4 Roadster. Take that into consideration too.
