I know what you mean, you're just saying it wrong. The stroke on the front shocks is too short, it has TOO little travel. It's something like 4.25" or so. And with a close to stock rate spring, if I remember right, well over half of that travel is eaten up. You'll also notice that the stock springs are preloaded a pretty good amount, like enough to be fully extended after you pull the motor.
I think, and I know I've posted these thoughts in the Gixxer Drew thread on SF and on here in places, that the stock dimension rear shocks can work with stiffer springs but will need a revalve. I also think it would be possible to get the stock rear shocks on the front of the car, they'll also need stiffer springs and a revalve. But I never tried because I don't need to and no one wanted to pay me to try it, but I don't see why it wouldn't work. The setup I built uses the same length shocks front and rear which I think were a couple inches shorter than the stock rear damper.
But if this is going to be on a drift car, I would highly suggest that you do not do the Gixxer Drew setup unless you try what I said above. The price will be awesome for what you get, but you'll still be around the price of normal entry level coilovers. Go with something with decent spring rates. I don't even know what spring rates stuff is coming with anymore but I do remember a lot of them coming with a weird split, meaning the balance between the front and rear spring rates was not right or balanced like it should be. I ran 1000lb/in in the front and 600lb/in in the back and it was awesome. I built another set running 1300lb/in in the front and 700 or 750lb/in in the back and I've been told that it's awesome as well. Both setups designed for drifting. Both setups also rode very well but they also weren't cheap. But look for my old posts on here and SF, tons of info.
