I've been assured by Milledge that an early car could get down even 75 lbs lighter.

Rear spring rates are not a problem if you know where to look. I have 32mm (effective) hollow t-bars and can get up to 34 or 36 (can't remember which). That will be more than enough.

The intake is not so much the problem on the 8v 944 as the cam. No overlap. It's quite limiting.

Broadfoot....

Well, since you asked, I've yet to see a photo of a Broadfoot built/prepared IT 944 that was legal. I don't think Albert knows the IT rules or doesn't care. I pissed him off on Rennlist when I mentioned something that was illegal that he was talking about. Most of the stuff is minor, but still quite illegal and not even a grey area. I don't know Albert, but those who do think highly of him, although I've heard many many stories of his shop being very very very slow.

I'd personally stick with Milledge.
