Springs are sold but for 50 euros you can have the advanced alignment specs and step by step instructions on how to modify the geometry. It's a lot more than just removing strut pins, more modifications are needed and the specs are derived from a racing co in germany.
Due to new parking configurations I sadly had to revert back to the stock springs and give up the balanced handling and classy drop. Take my word for it they were even smoother than the oem springs of the adaptive suspension on road imperfections.
Anyways up for sale my Eibach Sport springs kit designated for 35i and 35is in top condition and in original package. They have been serving their purposes for a year and a half and have covered 6.000km.
The price is 140$ and shipping cost worldwide is 85$ (a rather big box weighing 9kg) for a total of 225$. UPDATED PRICE 125$ + 75$ FOR SHIPPING
As a bonus I will give you for free an alignment recommendation for which I paid 200 euros to a racing team in Germany - and I mean I paid 200 for the information only - that gives more camber to the front wheels, even more than just removing the strut pins and results in eliminating understeer but not losing balance and top speed stability.
Price in euro is 110 and 65 respectively.
Thanks for watching.
