Throwing suspension on. Daily driver. Will be using H&R Race springs 50404-88. Most likely going with Front Shock: Koni: 8641-1210SPORT and Rear shock: Koni: 8041-1186SPORT.

Car has new Revshift 95A green subframe, trailing arm, and diff bushings. Has OEM BMW offset control arm bushings, but I may replace those with the Revshift offset or regular CAB’s. Has stock IS sway bars. Has a Z3 2.7 rack. Will most likely use Revshift 12mm RSM’s.

I’m wondering what MM spring pads to use front and rear? I am looking for driveability over looks, although I do like the lowered look, I would like to avoid scraping the oil pan etc. due to going too low. What spring pad sizes do you guys suggest to go low, but not so low that it will cause problems? Any idea what the stock spring pad thickness is front and rear on a stock 1989 BMW E30 325IS?

I believe I will be using Leomferder upper strut mounts, Or would camber plates be better? I’m not that concerned with adjusting the camber.

Also wondering if using these front upper strut mount reinforcements is a good idea to help strengthen the front shock towers? https://www.fcpeuro.com/.../bmw-strut-tower-reinforcement...

Any other parts/hardware I should get to do this?

More detailed: I'm saving up to eventually do a rack swap because my original is slowly on the way out and I want to pull and rebuild the sucker myself or have it done locally, but there doesn't seem to be a way to filter for the right spec of rack or search by part number on the likes of car-part junkyard search. Is there a way to easily identify ZHP cars or do I just have to get under all the damn E46s in yards local to me to find the right rack?

Should I put the stock springs back on or is there some other solution to this issue?
Thanks
