I recently did a set of 240z struts for a buddy, where we dropped the AW-11 MR2 inserts in the housings, shimmed from the top (de-stroking the insert, but shortening overall length) and drilled out the stock gland nut. We cut 4 coils off the stock spring, so we still had almost 2" of preload on the spring. Surprisingly, it drives smooth. He was on a low buck budget, and we had many people scream not to cut the coils, but as long as you keep preload on the spring, it rides well. Dare I say, it rides better. It's a little stiffer than stock, but works smoothly. Now that said, being someone else's car, I did not drive it too its limits, but I never felt the car bouncing on the bump stops.... oh, and that's another thing, we cut some polly cone bump stops about in half, to allow for as much travel as possible, but still have something there.
