Alright here's the story... I used to have Ground Control coilovers on Koni shocks, with custom spring rates. It was an awesome setup, and the car looked great, but I got tired of the SUPER stiff@$$ ride. So, not wanting to spend any money (given the mileage on the car) I sold the GC's to Alexander on here and threw my stock GS-R springs back on the Koni shocks. Since the Koni spring perch is adjustable, I decided to put those on the lowest setting so at least I wouldn't have the total 4x4 stance of stock springs.
So, with GS-R springs on Koni shocks, still with the ITR 22mm rear swaybar, the car rode great, handled real nice w/ the shocks on full stiff. However, the rear was WAY higher than the front. The front sat real nice, but the back was quite high, as you can see:

So I figured some ITR rear springs would help even out the situation. I searched high and low on H-T and on eBay and on local boards, and finally found H-T user nholmes with a set for sale. I picked up all 4 ITR springs for $100, but only installed the rear ones.
Here are the ITR springs (progressive rate for the back) next to stock GS-R rear springs

With the Konis on the lowest perch in back, the ITR rear springs fit on w/o the need for a spring compressor. A spring compressor was required for the GS-R rear springs. According to this site: http://php.indiana.edu/~bchang....html the ITR rear springs are progressive rate from 140 to 246 lb/in. Stock GS-R springs are only 117 lb/in. The GS-R front springs are 212 lb/in. So this setup should help reduce understeer from using all 4 stock GS-R springs.
The car looks MUCH better now. I haven't really pushed it as far as handling since I put the springs on 2 days ago, but so far it feels pretty nice.

So my current setup now is: stock GS-R front springs, stock ITR rear springs, and Koni Sport adjustable shocks.

yeah it's amazing how adjusting the shocks alone changes the ride quality... from nice n soft to stiff and well-controlled. I just wish the springs were a little more even.
I know if I ran the ITR springs in front, it would either be super slammed, or it would be higher than it is now (if I raised the perch back up). It kinda sucks that you have to use different springs front and rear to even it out.

why do you say that?
I would think the itr springs in the front and rear would be a better setup than solely having them in the rear.
basically an itr stance and handling except better due to your koni shocks.
I have my stock gsr springs and oem shocks for my winter setup, but picked up a set of ITR springs in place of the stock gsr springs....plan to swap out all four.

I like the front end where it sits now. If I were to put the ITR front springs on the Konis with the perches on the lower slot (like it is now) then it would be very low in front, probably about as low as I had it w/ the GC's... but it would still be higher in back.
If I put the ITR springs on the front w/ the perch at the upper slot, then it would be higher than it is now. But I like it the way it is now.
As I said, 212 lb/in in front and 140 to 246 lb/in progressive in back. I was running 380 front and 450 rear on the GC's, so I'm used to having stiffer springs in back (easier to get the car to rotate, less tendency to understeer).

Man, when you said stiff... I love it though, still getting a bit used to being as low as I set it at. Your setup now reminds me of my previous, H&R OE Sport springs all around - very comfortable ride.
Your current setup looks nice - kinda miss the soft springs but i'm not commuting Senior year so I don't have to deal with it every day for 60 miles

Well the rear spring rate makes a bigger impact on ride quality, and I had 450 lb/in in back. Things would bounce you out of the seat over big bumps.
i have ITR springs all the way around and i remember needing a spring compressor to get them into the struts, but when i look at it it's nowhere near as high as stock. i compared them to stock ('95 LS) springs and i'm pretty sure i remember them being only a bit shorter than stock but much thicker. it was a long time ago and i don't really remember and stupid me didn't take any pics. anyways,

well you can look at my pic and see the difference between the 2 rear springs. With the Koni perch on the lowest setting, no spring compressor was needed. In fact, the spring was slightly loose when everything was assembled, until I bolted it back onto the car.

The front perch is 1" lower than stock.
The rear perch can go either 5/8" lower or 5/8" higher than stock.

Not sure, haven't gotten an alignment yet, hopefully this week.
