Sounds like exactly what I want for my non ZCP/EDC E90. Currently on 19" ZCP 359 wheels with 265f/285r Continental rubber. Would this mix-n-match suspension combo be a good mix with 15mm f / 12mm r wheel spacers?

And further more...Anyone have pictures? I saw the one posted recently, but the rest of the links are dead.

I have this exact same set up, including the modifications to the top hats and bump stops. I absolutely LOVE it - shoutout to Malek@MRF for sharing this fantastic DIY and information.

It is comfortable enough on the street, much tighter than stock, but in no way too extreme. Yet it also does great on the track. Its the best bang for the buck suspension setup for the car in my opinion. Totally transforms it into a much, much sharper tool!

Pics below with 15mm F, 10mm R spacers, stock ZCP wheels & tires.

That looks great, 6ixSpd. It looks like 275 rubber up front (kudos to you) with the 15mm spacer. Any issues at all with that? What size tire are you running in the back with the 10mm spacer? I've been considering the 15mm F / 12mm R with my 265/285 tire combo.

Wondering how this will match with my E90 without ZCP or EDC compared to the intention of the thread on a ZCP E92. I'm hoping for similar (identical) results!

I should've clarified that the first 3 photos are with the square rear setup and 275/30/19. No front spacers.

All photos have 10mm rear spacers. Pics 4 & 5 have the stock rear 265/35/19.

The front 19x10 ET27 and 275/30/19 sits 99% identical in ride height and flushness as with the stock 19x9 ET31 245/35/19 + 15mm spacer set up.

So for illustration purposes, there is zero difference up front between 19x10 + 275/30/19 vs. 19x9 + 245/35/19 + 15mm spacer.

Car looks great! What springs did you end up going with?

Also, what rubber tube did you get for the rear coil / perch - Is that something you just picked up at a local hardware store?

I have H&R springs on my non-ZCP E92 , and they are nice on smooth streets and highways, but with anything bumpy including canyon roads with mid-corner bumps they hop around and really struggle to remain stable. I'm looking at a) this modified set up by MRF b) going back to OEM springs or c) going with OEM ZCP suspension.

To that end, can you actually install a ZCP springs/struts on a non-ZCP car? Any install issuess or concerns?

Thanks. It's on H&R Sport Plus (aka Race). Same drop as H&R Sport but stiffer. I absolutely love it and won't bother swapping to coilovers until the stock shocks give out.

I can't recall what rubber sheath I used for the rear springs.

Did anyone ever measure the front bump stop and the e36 bump stop to see the difference in length?

Awesome write up! I'm going to take this to the local Bimmer shop and have my car done right! I came close to getting the KW HAS kit for my e92 M3 ZCP. Glad I ran into this post.

Put them in a vice and use an angle grinder to chop of the desired mount. Use a file or a table grinder to smooth the cut.

I was fortunate and had access to a cnc-mill. Could likely modify one (stopping to compare against the un-modified periodically) and then match the height for both

The one aspect of this hack that doesn't make sense to me is the removal of the rear spring pads. The rear already looks or appears to be lower than the front, so why make the rear lower by removing the pads? IMO all the mods and/or hacks should be made to the front end. I installed springs the other day where I removed the rear pads and supplemented it with a rubber tube which resulted in the rear being much lower than the front. I re-installed the pads and now its back to what it should look like.

I also have the same question, I am currently retrofitting my E90 EDC non-zcp with e90 ZCP edc suspension. I am trying to follow the exact example:
1. Shave top mount
2. E36 Bumpstop
3. Spring pad (Need clarification)


I am planning to use the Dinan springs. These springs are meant for non zcp as Dinan never made a zcp spring. The question of concern i have revolves around the spring pad removal. In the dinan instructions it says remove existing rear spring pad and replace with the dinan rear spring pad. In the step by step, its suggested to remove the spring pad on the e92. Someone shed light on this.
