Lowering springs

[Marlon]

H&R or Eibachs?
Looking to improve the aesthetics and reduce my arch gap, however its a daily drive and I commute through speed bumps and poorly filled potholes. Currently on SE springs and rides quite smoothly, so not wishing to compromise too much but really want it to sit a little lower and improve the stance. I'm really only wanting to swap the springs, I don't want to tinker with anything else on the suspension.
These are the H&R springs I'm looking at - its a 35mm lowering, which doesn't sound much at all?
Comments, recommendations please

H&R all the way if keeping stock shocks. Far more compliant & less crashy than Eibachs, the cheaper stuff is just avoid

[bobo075]

I would say eibach pro kit... I find them softer than the H&R...

When I was researching this I thought the H&R were generally regarded as being much firmer and also lower than the Eibachs?

I went Eibach and they are great. Being progressively wound they are much better at soaking up the smaller bumps whilst being firmer under load compared to standard.

H&Rs are designed for compliance & comfort until you hit the twisties then they stiffen on sideways pitch , Eibachs in my experience give you little damping on the front & any decent ridge or hole will feel like its damaged the car
had 2 Zs on H & RS / 2 on Eibachs , i would never purchase Eibachs against H&Rs unless with the Bilstein dampers .
Driven a good few miles in Number5s Z4 with that set up & it really is quite impressive compared to stock Msport shocks & springs

If you're worried about hitting speedbumps, ignore the h&r's. They are far too big of a drop for daily driving where speedbumps become a factor. Jonny Essex had them fitted to his Zed at one point and it was much lower than mine with Eibachs.

I do around 100 miles a week in mine. Not huge mileage, but it's driven every day to work and back, including on a huge private work estate with massive speedbumps and even across train tracks, no problems here if taken at a steady (slow) speed.

I did mine a few year back with H&R after a month had em taken off sick to death of grounding at every speed hump.
Tbh my mtech springs are good all rounders .

Definitely Eibachs, H&R are know for being lower and firmer

Eibachs with Bilsteins though , the ideal combo

[mr wilks]

Pic from this years France trip , H & Rs on the left 2 cars & Eibachs on the 2 silver ones though the Alpina is on Bilsteins , can't recall any issues grounding with any of the cars same on a recent run in the Dales with Z4MO who i think is on H&Rs

[mr wilks]

Worth a read here Colin before you make your decision , the description of the Eibachs crossing expansion joints in road or patchy tarmac is typical of my experience with them & that the H&Rs closely reflect the oe spring rate whilst under normal driving

Personally I hated eibachs on bilstein b4, crashy and didn't last more than a winter on the Zed. No experience of h&r, but 35mm seems quite a big drop

[Marlon]

Lots to consider, thanks everyone. The more opinions the better imo as I can make a more informed choice.

Did the springs snap or did the shocks give up? Only asking as I replaced my shocks early this year, so will keep an eye on them.

Can't say it feels crashy though. The ride is quite forgiving with the eibachs/B4 combo. 3 of my sport shocks had completely failed though, so anything would feel great compared to that

B4 with eibachs were noticeably harsher than the b4s with se springs, although eibachs and fresh shocks b4s were miles better than knackered shocks and M sport springs. I think the bilstein/eibachs combo Mr wilks is referring to in relation to Number5's car is the b8 shocks also know as the b12 kit. This does give quite a firm ride.

Never tried H & R myself so it's interesting to hear what Mr Wilks is saying with real world experience of these. I've always been led to believe on here and other forums that both E85/6 specific and generally H & R were harsher than Eibachs.

What I can say is Marlon the comfiest setup is what you currently have now (se springs) so if you value ride quality it might be better to stick than twist. It's also better on poor bumpy country lanes etc (no bottoming out). Its not as aesthetically pleasing but it certainly is form over function. I know its not what you want to hear but at your cars age/mileage the single best thing you could do on the suspension is change the shocks, they're bound to be knackered, which might not be apparent till they are off the car so if you do buy springs be prepared to hear you need shocks from whomever you get to fit the springs. M tyre sizes might be a better way to fill the arch gaps somewhat (I've gone this route) but they bring their own issues, its part of the reason I put a 3.64 diff in mine. The chunkier tyres will fill the arches a bit more though and do give a bit better ride quality.
