Recommend a rear upright/hub

[adamwatson]

I'm doing an MGB with a Saab turbo motor putting out 300+bhp. Plan is to use a BMW E46 box and diff. I need to decide on rear suspension and hubs. It looks like I'll be building a custom subframe for the diff and custom wishbones. Only thing I can work out is the rear uprights. Audi a6 quattro ones look promising. Can anyone recommend anything better?

How about from a Mazda RX7 FD. Aluminium wishbones! Go the whole hog and use the diff and shafts as well, they can take a LOT of abuse and have a TorSen limited slip differential.

There's always a few being broken on FDUK forum.



Good luck with the project, the B204 is a good starting point.

What are you running at the front?

Nissan S1x might be an idea for the rear.

Rx8 will give you ally arms lsd and pretty good Geometry just needs a jig to re make the carrier assembly at the width that works .,shafts will need shortening but I've run sleeved ones on my Saab engined car with near 500 hp for years with no issues . Rx8 stuff is dirt cheap too

Thanks guys. Rx8 is a good shout, should be loads with dead engines to pick over

There's an adapter plate for the five or six speed RX7/RX8 gearbox on eBay for £50 for the c20xe. The XE has the same gearbox bolt pattern as the Saab engine, you could use the whole running gear from the Mazdas and discard BMW stuff.

£300 should get you a dead rx8 and pilfer the lot . Only useless but is the Mazda steering rack but you'll need to use something else to suit the narrowed subframe . Let me know if you need a steel sump flange to make a rear well sump as I supply laser cut steel flanges and I'd go with a 9000 as a donor engine for rwd conversions with the log inlet manifold
