So, I had been planning on modifying my GS-R for autocross, but then the autocrosses nearest to me lost their venue, and even when they had it, it was like 60 miles away, which kind of sucks. Well, they recently moved to a venue that is about 10 minutes away, so I'm going to start going again.

Now, I'm also planning what I'm going to do with my GS-R now that I've decided to start racing it. So I'm reading the suspension forums and the auto-x forums, and I'm finding that the GC/Koni setup is very common, so I'm slowly settling towards that. But I was thinking about the spring rates, right? Everyone tends to run about 100 pounds higher in the rear than the front to help the rotation, yeah?

But, we all know that the Type R is considered one of the best handling front wheel drive cars ever, hell, one of the of best handling cars regardless of drive. So I decided to see what it's spring rates were.

They're a linear spring in the front, at 246 lbs/in, and the rear is a progressive spring, that goes from 140-246 lbs/in.

So, I'm thinking...Honda must know something, so why not increase those numbers like...20-30%, and get custom GC's with those rates?

With my admittedly limited knowledge of the black arts, it seems like it would handle like a stiffer Type R, ride more comfortably than most setups without the super stiff rear ends, and be a little more forgiving as well, because the progressive nature of the rear end would give a little more time to react.

What I want to know is:

Has anyone else already tried a linear front/progressive rear setup like that?

If not, does it seem like I'm crazy, or does it sound like a good idea?

30% would put the front at 319.8 lbs/in, and I think the Eibach ERS springs that GC uses come in 25lb increments, so my initial guess would be to do a 300f/175-300r or 325f/200-300r.

I would probably pair this with a stiffer adjustable rear sway bar, since I know that the larger rear bar of the ITR would come into play as well.
