So I talked to 180 customs and he said he thinks he remebers doing the install but the rear was kinda low so he had to put a special "plate bushing" to raise it....does anyone know what this means?

I'm pretty sure these were the coupe springs and not the X coupe springs. Typically the different models will have different front to back weight ratio differences. The X might be heavier in the back and if the regular coupe springs are installed, may require a plate bushing below the springs to raise it a bit. The coupe rear spring may compress more if installed on an X therefore making it too low in the back. Basically the plate bushing would be like a giant washer. This would balance the drop but would make the ride a little stiffer in the back. Here's a pic of the Swift Spring spec sheet. It does not show springs for the X so my guess is the X springs still have not yet been developed.

Thanks for the chart Bota, that's interesting, especially that they have the same part # for the G35 & G37 Sedan and list the drop as the same for both models. This isn't true if comparing models w/ Automatic transmissions. The 7AT is about 140lbs heavier than the 5 AT which will result in about a 1/4" to 1/2" deeper drop in the front. That's the reason the Eibach (and I think Tanabe) have different part #s w/ higher front spring rates for the 09+ sedans. Too bad they don't have an application (or at least one we're aware of) for the X coupes, obviously they're missing some decent sales.
