Flange Shaft #15

Has anyone experienced this? Can I replace both existing 2.7 axles with Boxster S axles? Any recommendations?

Thanks

The axels, flanges, brakes, and suspension carrier hubs are different on the S, which is why rear S brakes cannot be bolted onto a base car. You need to either switch the flanges on the Tip, or get ready to spend a lot of money to convert the rear of the car over to an S configuration; a waste of money in my opinion…..

Thanks for all the advise. The dealer wants $300 each.
Anyone have a set of used flanges for sale or know where I can get some?

Seems a lot easier to me to just swap the output flanges on the transmission. I would try calling GBox and/or OK Foreign, new, they're not going to be very attractive.

When you swap flanges, I would also replace the output flange seals.

What happened to the flanges from the first trans?

I got the car at auction without the transmission. I have been buying all the parts from members on this board. I am almost done, just need the flanges and I can get it driving again.

Will the 2.7 flanges fit into the 3.2 transmission?

They should.............

I think so. When I had my gearbox apart and installed my Guard diff, I remember when looking through the parts diagrams that the base and S cars used the same major diff components, so the output flanges should interchange.
