You have Scott Giles' contact info? He had the fastest one at the ARRC a few years ago...
If we're talking about Scotts red car, it was a later civic ('88-91). For the earlier models, I beleive people are using between 400-600# springs, depending on setup. You want to acheive max rotation, without the rearend completely coming around.
What is the setup ont he rear of the car? Stock Swaybar, aftermarket, combo, dont know?

i do not know scott g. right know there is no rear bar and 350 lb springs. i still have a front bar. it has 29mm torsion bars. i was going to order a aftermarket bar for the rear. i was going to disconect the front bar.

do you have limited slip and final drive upgrade? this will make a difference on what front bar, if any. i had some issues with losing traction on the inside wheel depending on front bar and front springs.
i have 27.5mm front and 450# rear springs with a 3/4" adjustable rear bar (stock rear bar removed) and stock front bar. i too have too much front roll.

In my 85 CRX Dx setup for ITC, I have an adjustable rear ~3/4" sway bar and 600 #/inch springs which combined with the front 21mm sway bar and either stock or maybe 23mm front torsion bars, the thing is pretty quick and body roll is not too bad. I have either a stock final drive or SI and the Mugen LSD which works pretty well in the midwest.
I'm running the same setup as Tom or I was up until the end of the season. I remove the swing axle/internal swaybar and replaced them with the left side axle stub. I also disconnected my rear 3/4" swaybar. I think I'm going to reconnect it as I feel it has a little too much roll.
On my girlfriends Civic we are running the ST rear bar, I'm not sure what the spring rate is but i'm going to have to say at least 450's. The front swaybar is disconnected and the car rolls far to much for my liking. I plan on reconnecting it. The car also is lowered too much and I plan to raise it up at least 1/2 an inch.
From my experience I have found that the CRX is a lot more twitchy then the Civic. I have had two of each at this point and still can't decide which I like better. I do tend to like the car to be not sprung too tight though. I do like a little bit of roll.

Yeah, Scott's car was a 88-91... completely different animal from the earlier cars.
FWIW, Richard Floyd over on RR-AX.com has a fast ITB CRX (had? It got crunched at CMP and is being fixed). It's not quite the same as a Civic chassis but it might help you get in the ballpark.

With 29mm t-bars I would loose the front bar use 600# rear springs and weld up the sway bar that is inside the rear axle. That is what I set my friend Ivan's 86 CRX up with and it was great.
