So I've just ordered an AP shocks and springs combo from DPM, and want to know what else I should change while I have it all out such as bumpstops/spring seats/ rear top mounts etc (basically stuff I haven't thought of that is worthwhile changing) bearing in mind the 30/20mm drop that will accompany the new suspension.

Recent parts already on the car:

Standard front top mounts: 8 months old. (thinking I should change them to LCR while I've got the opportunity)
Standard front rear non voided bushes/powerflex on control arms.
New ball joints/tie rod ends/droplinks

Gruvenparts poly-bushed adjustable lower control arms.

Any suggestions would be greatly appreciated!
