I've spent the whole day yesterday going through every single thread yesterday going over the issues of swapping springs/schocks/pads etc.
bottom line is, i dont want aftermarket components because i want the ride exactly as is. not any firmer or softer.
as for swapping the pads, they will drop it a max of around 21mm depending upon if i go the extremes from #4 to #1. but then again i have yet to figure out where these pads are and how i can count the numbers on them.
perhaps if there were factory specs available then i could swap the OEM parts for new OEM parts.
