Installed Eibach Z4 3.0 lower springs .8” drop

[kappa_md]

Other than the kerb weight, dampers have been revised thus accounting for the height differences. I’d still go with US Spec for the MT.

Nope. My only suspension mods are what's listed.

What's your assessment of the Eibach springs combined with RE71RS in autox? Did you find that the Eibach's soft springs rates overwhelmed by the RE's grip?

Love them. I’m not fully prepared to SST rules but still pax top three at my local club events and around top 10 or so at a couple bigger regional clubs I’ve gone to this year. If you want to go all out and prep the car to the max under the class rules then a more aggressive spring or full on coil overs is a better choice but if you just want to be “competitive” but still very much DD comfortable then these springs are gonna be hard to beat.

Quick question, my E10-20-046-02-22 springs arrived today . Surprised not to see any bump stops in the box, I know some people have trimmed them, but also that others have new ones supplied. Expected the newer kits to come with. Odd it's so inconsistent. No spring isolators either, assume I just move those over from OEM springs and fit in the same place?

Cut off the bottom donut and reuse everything.

I have RSR Down Springs, 0.6 to 0.8 drop, similar to the Eibachs.

Tires are 275/35/19, 305/30/19

Front

Any rubbing issues up front? I'm wanting these springs and run the same size up front with a 295 on the back.

I have same springs installed. Mine came with rubber/plastic silencers on rear springs. The install shop cut smallest (bottom) of the 3-part shaped bumpstops all around. The ride is so great!

Thanks for confirming, this is what I thought, some kits have, mine doesn't.

If the coils are a different thickness I won't be able to transfer my spring isolators Will need to look into it and contact Eibach.

You can look into amazon or ebay for Tein isolators large size, make sure large

Using time off work to get the springs fitted. Fronts done no problem.

As for the rears, can anyone confirm it's here I cut the rear bump stop right?

Also, what a nightmare getting the lower arm bolt out, dreading putting it all back together based on comments here. Going to order another as the impact gun made a bit of a mess of it. Anyone know the part number?

Edited - I think it's 90118-WA291

Yes on the cut. Also not as bad as it sounds lining the rears up to reinstall the bolt. I just used a long screwdriver. Line it up best you can then put the screwdriver in and use it to line it up further. Bolts went right in. There’s also a specific tool you can buy for this purpose but a plain old screwdriver works just as well.

Thanks for the advice. Did you reinstall the bolt before or after reattaching the shock absorber? Not sure what order is easier.

Did the instal a while ago so my memory is a little hazy but I’m thinking those bolts were last.
