Installed Eibach Z4 3.0 lower springs .8” drop

[Sereph102889]

No just the fronts, I’m doing the rears later this week. I’ll see if I can get to them for trimming but I’ll anticipate pulling the shock out. No big deal. The rears don’t loo too bad.

The rears are easy until reassemble. It takes maybe 15 minutes total to remove the rear shock once the spring is out, it's only held in by 3 bolts that are very low torque. Once it's out, hit the perch bolt with an impact until it comes off and then you have straight access to the dust boot and bump stop. I think this will be easier than trying to finesse the bump stop out of the dust boot and down the shock body far enough to cut it. Once that's done just reassemble the shock and put it back into place.

I pray you don't have the issue I had when reassembling the rear. My bottom shock mount wouldn't line up with the bottom hub mount pivot hole and it caused me some serious grief. I had to go buy a pry bar and cry in a corner until I finally got it to work.

Thanks for the info I fully suspect I will need to use a prybar to line the hole up.

Finished the rears yesterday morning. So Z4 springs, Whiteline adjustable front sway bar and end links, SPL rear adjustable endlinks.

These pics were right after install (I also have Burger 13mm fr, 15mm rear spacers), so I expect it to settle some more, then an alignment next week. Zero issues, no clunks, squeaks, rattles, etc. I was very careful to torque everything down. Car has less roll and turn in feels faster. I’m really happy.

hello! i have 275 front tires, does anybody know if using this eibach z4 springs cause any rubbing issues? thanks!

Those of you that drive a bit like hooligans, have you noticed any negative effects such as increased wheel hop or anything of that nature? This can happen when a spring is not properly matched to a damper.

I'm looking to get rid of a bit of wheel gap but don't want to compromise as I quite enjoy the stock setup, comfort, breakaway characteristics, how easy the car slides and what not.

I don’t launch my car from a stop so I can’t comment on the wheel hop issue, but I do track my car. The car is less prone to being unsettled over rough patches (like ruble strips) or sudden suspension unloads and reloads (like cresting hills), and the oversteer from things like trail-braking is still very controllable and useable. Comfort feels the same. I really like the setup, but it still has too much body roll for me so I’m installing adjustable sway bars tonight.

I don't launch either, still it would be comforting to know that it doesn't hop if it breaks traction going straight ahah.

~ As the OP… I can assure you the car doesn’t hop at all when launching aggressively from the hole. The cars rear end simply squats and squirms right and left seeking traction as stock.

Looks like I can finally join the club. Wheels are 18s which is why it doesnt look lowered.

Edit - better picture.

Just to confirm, this is the correct spring?

Figured I'd buy directly from eibach and it's a little cheaper than ebays listing

Another project complete... daytime photos to follow (now attached). Worked late into the night.

The revised ride height looks great!

Amazing!! Worth the hard work!

Sweet. Just placed my order.

With that kit you can also go for 20” wheels without problems
When changing the springs you can also go for spacers.
Installed mine this wknd and can recommend

~ Spring can’t come quick enough… ready to install these staggered 20’s on my Supra. Can’t wait to ditch the oem black wheels. These should transform the car.
