I generally don't have a lot of trouble getting around 3.2 Carreras on the track either, for what that's worth - although of course at that point you're comparing non-stock cars with different drivers and it's basically meaningless.

I think there are a few factors here. Probably your '78 has worn tie rod bushings and could benefit greatly in turn-in steering feedback if you install the "turbo" tie rods. May also have worn bushings elsewhere in the suspension.
Second, I think the caster settings of the two cars are significantly different (M3 has a couple degrees more) and may affect turn in feel.
Third, the M3 has power steering and probably a faster steering ratio. no doubt this affects the feel a bit.
Fourth, the 911 really needs its front suspension loaded by braking just prior to turn in. There is some technique to this weight transfer. The need for careful weight transfer is partially a property of weight distribution. However, we have seen a lot of successful racing vehicles with around the weight distribution of the 911, so I don't think you can say the 911 weight distribution is bad.
Last, certainly tires can be a huge factor.
I'm not saying a stock SC (or similar) turns in better than a stock E30 M3, maybe it doesn't. but there are a bunch of factors at work.
