I know the stock spring rates are tuned to give the car a more loose rear end, [...]
Perhaps it's time to look for a suspension setup that would give the car more neutral handling.

How much noise were the tires making? Are you positive you were already reaching the limits of grip or was it your first time toeing the line at those speeds and it's possible that there's another 1/10th of capability left in the car you're not accessing?
Sorry, I just find it hard to believe that with significantly better grip (Rivals to Primacy's) you're lagging that far behind in the same section, my money is on either there's more grip that you weren't using or your tires were worn out before you got there. Check out how much tire noise CSG Mike gets on this session. Now I'm not advocating you drift every corner, only that there may be more grip than you think, I am working on stepping up to that limit as well, finding that limit is not easy.

I'm on stock springs/dampers as well and I've been fighting understeer understeer understeer, all oversteer has been driver induced (and a good chunk of understeer as well). Camber works wonders on this car and may be something your buddy also has a big advantage on you with coilovers, I'm up to running about -3.0 degrees camber autocrossing up front (no adjustment in the rear yet, @ ~-1.4 degrees) and I'll be trying more soon.
