H&R springs or Eibach springs?

I would not be surprised if the OP discovers that the Eibach dampers are leaking. My rears only lasted about 23K before the seals gave up. Eibach was not at all helpful. They were just out of warranty - fair enough - but they would not sell me new replacements and wanted a long time and a kings ransom to rebuild them. I went with TCK SA.Old, not obsolete.

Yeah to my knowledge Eibach themselves provide guidance on bump stops for spring applications to other cars, but in my searches I haven't come across an official confirmation either way for our platform.
Given they're very slightly stiffer than stock, maybe they aimed to compensate for the drop all else the same? I guess at the end of the day it's unreasonable to apply lowering springs in isolation and expect a 1:1 ride. This setup is the only one I've known the entire time I've owned the car, but the crashiness has never sat right with me.
Anyone out there want to bench test the least sexy aftermarket combination for our cars? It's always been a burning question in my mind even if the actual answer is to cut 0.5mm 😂

Seems the real answer to regain that travel is camber plates, but given I have no other practical reason for them, that'll probably wait until I have a wheel setup that necessitates them.
Which leads me to think that maybe Eibach determined that there wasn't a drop spring + bump stop solution that worked well enough to hit a sweet spot on our cars, and in the absence of one advising to leave as-is was less liability for them whereas a decent compromise can be found with applications to other suspensions.
Funny how Koni / Eibach has been the go-to for so long as a no-brainer upgrade, but after all these years we find that it's a pretty significant tradeoff to get that mild drop. Maybe we're all just getting old.'04 LSB Coupe 6MT

As to being the go-to, who even started the whole idea that lowering was so great for the car? Companies selling springs?Last edited by 01SG; 08-07-2024, 12:24 PM.

But with regards to our cars I imagine it became so because Konis are an affordable replacement for tired OE shocks/struts with slight adjustability, and Eibach is the path of least resistance to achieve a mild drop on a car that has a bigger wheel/fender gap than most of us want.
Upon further thought I'm going to revisit the settings on my fronts, as perhaps a stiffer than average setting would go a ways to mitigate some of the bouncing and chassis shattering impacts from full compression scenarios. I've been mostly thinking about bump stops and ways to increase suspension travel but that's probably the first place to start. A lot of general advice or discussions in the 20+ years of archives have come from the angle of dialing it towards OE-like stiffness for 99% of drivetime scenarios, whereas the thing that bugs me most is the 1%.Last edited by dukeofchen; 08-07-2024, 02:13 PM.'04 LSB Coupe 6MT

While I dont have any experience with the Eibach springs, I have no complaints with the HR sport springs. Has a good stance, and ride is not overly stiff on the street. Sure, it could be lower, but when drifting and the suspension is fully loaded, it tucks nicely and I havent had any rubbing, front or rear, on 18x10's square. I also dont have to worry about getting in and out of driveways.
