Maybe a little higher? Effective rate of a 30mm torsion bar on a 924 is 335 lbs. Unless they are hollow, then it is 292 lbs.

That's quite low - I ran 400, 350 might also suit you.

Hmm, I guess I should also ask whether I will hate the ride quality of the 30s!

400 = no street ride quality and loose teeth.

400 wont be that stiff. I have driven a 931 with 700 at the front. That was pretty stiff, a bit to much for a street car. Harsh ride quality is mostly due to the damper stetup.

We've got dinosaurs in Boston too

I ran 25.5mm rear bars with 200# front springs on a '77 and I felt it was not pleasant on city streets. It was a couple hundred pounds lighter than a 931, but 400# & 30mm would be torture in any model.

Right now I'm running 200# fronts with the stock 23.5 torsions with bilsteins and I feel like it's just the right balance between pleasant in the city and responsive in the turns. Just food for thought.

Ugh, there are NO roads that look like that around here. Seldom freezes, temperature variations are quite low compared to other places.

I'm goin for it.
