So how much do the different springs drop the car? Eibach, H&R, RD-SPort?

aus · 10-07-2009, 08:29 PM

I'm just wondering how much these springs actually drop the car?

I've seen pic's and it seems like the drop is Eibach with the least drop, then H&R followed by RD-Sport with the most drop, but how much do they lower the car? Anyone measure the differences front and back?

This post helps, but any info on the RD-Sport?

too bad RD doesn't offer specific springs for the E93

Vic55 · 10-08-2009, 10:01 AM

No measurements but the RD drops the car approx:

1.2" Front
.9" Rear

SV Concepts III · 10-08-2009, 12:03 PM

H&R rates their springs at 1.0" F and .6" rear. The Eibachs are listed at .8" F and .6" R.

and do they recommend putting it on E93 or no?

I hear a lot of good things...

FruitCake · 10-10-2009, 03:30 PM

based on my research and previous experience I would say

Drop (highest - lowest): Eibach > H&R > RDSport
Performance (best - worst): Eibach > H&R/RDSport
Comfort (soft - hard): Eibach > H&R > RDSport

Yes, my conclusion is that Eibach's will perform the BEST out of all the springs, maybe only surpassed by Dinan but only because Dinan comes with different mounts etc.

so guys what about AC Schnitzer lowering springs...i "think" they are made for ACS by Eibach, iirc, and drop the car alittle more than Eibach, but not slammed like HR and RDS...and I "think" ACS springs are spec'd by ACS to be more agressive/sportier than Eibachs...I don't have them but there's a forum member with a blue E92 who has them...(forgot his forum name though)

i know ACS isn't the popular choice around here, but any ACS spring owners out there?

aus · 10-24-2009, 09:37 AM

I thought ACS only had coils? They have springs too?
