Nicely done Slicer and Malek. Glad this worked out. Not surprised to see Malek and MRF were able to make this work.
I only see one problem: that red Eibach spring really clashes with the purple KW perch. |

I actually prefer the Eibach ERS spring as it has a thinner coil which helps retain spring travel in comparison to most other 140mm length springs which have thicker coils. Not to mention they are lighter, and any weight saved off the suspension is always welcome.

Looks like this solution would work just as well with the KW Sleeve Kits, as I have the same issue fitting a 9.5 ET 22 wheel in the front. Hits the perch.
How much are these springs? Last edited by Ervin87; 04-23-2014 at 11:54 AM.. |

Price is approximately $100 / spring = $200 for pair.

Without having a sleeve kit to view, and just looking at pictures, I doubt a spring swap would work.

Slicer, in your first post photo, is that with a 5mm spacer?

No, a 10mm spacer with a 18x10 et25 wheel, 275/35/18 BFG G-Force Rival. The Rivals run wide. I couldn't even get the wheel on the hub with a 5mm spacer.

slicer, if you don't mind, could you please share with us your ride height?
Judging by the first picture, if the spring is short enough to have itself and the perch to clear the tire, the height adjustment range (top of the threads) is very minimal. Maybe 20mm max? Switching from 170mm to 140mm spring length, I assume you were able to retain your old ride height? Reason I am curious about your ride height is that some prefer higher while others prefer lower. Reduced adjustability might cause different people to select different spring length to cater for their preference in ride height. Seems like HR makes springs in many different lengths! Another thing to consider might be the reduced adjustability in height could affect corner balancing the car? Have you corner-balanced it? Or do you plan on doing that? |

My ride height prior to the spring swap was approximately 25 1/8" from the ground to the fender. That translated to about 5mm lower than KW's lowest recommended ride height setting. I raised the spring perch by exactly 30mm to correspond with the 30mm shorter spring. That setting cleared but the perch was only 1 to 2mm from the tire. I raised the perch another 5mm to gain more clearance. This resulted in a ride height setting equal to KW's lowest recommended and approximately 25-3/8" fom ground to fender. I had wanted to raise the car slightly so this was ok with me. In order to clear my tires, I can only lower the perch slightly from its current point. I also have about 12mm of upper adjustment remaining. That 12mm wouldn't necessarily translate into 12mm of actual ride height. I don't really see how any other spring length would work. A shorter spring would run into travel issues (see my earlier posts about travel), and a longer spring wouldn't increase clearance unless you ran at a much higher ride height, or eliminated the KW helper spring, or installed a shorter helper spring.

UPDATE:
I tested the new Eibach 90nm / 140mm spring on the track yesterday and it performed flawlessly. No discernable difference in feel or performance from my original KW 90nm / 170mm spring. *As stated earlier, the key is to set your ride height at a level that the shock bottoms on the bump stop prior to the spring bottoming out.

Slicer, thanks a lot for sharing your experience. I think i may go the same route as I want to get rid of a 5 mm spacer I am currently using.
Interesting how you measure your ride height. Isnt it a preferred and more common to measure from the rim lip to the fender indicating the size of the rim. I run 10 mm lower ride height than zcp and it is my best compromise for the roads around here, i want to keep that. Will i be able to keep my ride height if i follow your suggestion? |

Works great for street and track. It feels exactly the same as it did before the swap. Only negative is the reduction in height adjustability (as outlined above), but that is a non-issue for me because the available range is within my desired height setting.

Did you use the original helper spring still? Only changed the main springs?

IND installed Clubsports with the Eibach front spring conversion for me yesterday.
About 500 mls in -- highway, some terrible city streets, country road, and track today. Awesome setup. Ran 275 NT01's at the track with no issues. Thanks to Slicer and Malek for leading the way on this.
