993 suspension conversion to 78SC (wide-body)

I can't answer the suspension question but as for "as light as possible"
How about a set of these quarter panels in carbon?

After finding this picture if I was to do it again I might go in that direction

Questions for you --

What's your intended use for the car? A dedicated track car has very different considerations than a street car . . . Further, if a street car, where would you be licensing it and what are the emission requirements for that jurisdiction?


what shortcomings do you see with the 911 suspension/brake setup as-is? You might be better off setting your sc up as a "best of" version if its generation (i.e. fully refresh the torsion bar suspension/bushings/shocks/etc.) and get it dialed in as what it is first. At a minimum, this would give you a good baseline for making subsequent changes (or even determining if such changes are preferable/warranted).

As for engine/transmission/brakes, going with a 3.6 engine would make for a FAST car -- the g50 tranny used in late 911s and the 993 requires modification to the rear end of the car to fit (along with a new pedal box and hydraulics), again -- you might be better off starting off mating it to a refreshed 915 tranny and going from there. Brakes -- the 911sc brakes (or carrera brakes) would have no problem locking up your wheels and provide very good fade control, going with bigger brakes has the "bling quotient" and could be more fade resistant, but bring to play proportioning/balance issues in the process -- perhaps simply going with a 930 setup could get you the best of both worlds.

Another thought -- I strongly suspect that, at the end of the day, retrofitting 993 running gear to the sc as you proposed above will end up costing you several times the amount you'd have paid for a well sorted out 993 . . . .

Food for thought?

Putting a 993 Weissach axle in a G bodied car would require grafting the rear of a 993 onto the front of an existing chassis.

Not even the Singer does that. An optimized torsion bar car can get you nearly as far for a road car.

Not true.....

Lightness vs $$$$ don't temped me the this stuff I want to spend my $$$ across a wide (very wide) playing field

Singer did not exist in 2004.

Are you suggesting there has been zero advancement made since then? (I'm not being facetious and am genuinely curious).

996 rear (and in one case front) suspension has been several times put onto 944 and with wonderful results.

It may be more tempting than you think.

If you look at where that quarter panel attaches, there is very little bodywork to do compared to welding on steel flares, metal finishing and then final bodywork.

I did steel flares the way the factory did because being a real 73 I figured a future buyer might appreciate looking inside the wheel well and seeing the weld just like the factory, but if I was more concerned with just making it light and sexy, I suspect that the cost of carbon quarters would save you a lot of labor costs, and you could sell you steel flares.

Here is a link to the 930 quarters in carbon.
Getty Design - Doors, Fenders, Hoods, Decklids, Tails for Porsche 911

Talk it over with your body guy and see how the two options compare by the time they are installed. I'd be interested in hearing his assessment.

Here are some pictures from this forum showing how it is attached

Oh Wayner, why do you tease me like this! I absolutely love the CF panels, the car needs front fenders anyway and the Getty front CF is on the list. but had not thought of rear because I have them. Repost this on my new thread Project Hanna if you would
