Cool. This was exactly the feedback I needed. I'll order the rear spacers only and wait on the fronts. I agree that 5mm should be avoided on the fronts because you don't get hubcentric. Gotta go 10mm to start getting that.

On the rears, I'll get the H&R DRA kit. In either 25mm or 30mm this kit bolts to the car's hub flange with included silver bolts, then you bolt the wheel to the spacer with the car's stock bolts. You pick up another quarter pound of weight from the extra bolt heads and the steel thread inserts, but it is a veeeery solid setup. Plus the added weight is at the center of the wheel.

Yeah.. 25mm or 30mm. Torture decision. I've determined that 30mm is not too much. The problem is that if you go 30mm and no front, you're introducing a tad more understeer. I replaced the suspension on the Coupe and drastically reduced understeer (and actually have oversteer now). But I'm sticking with stock suspension on the X so I don't want to induce much of a change. But If I do get front spacers after all, I'll probly wish I'd gone with 30mm in the rear and not 25mm HA!

Thanks for the advice.
