I recently purchased a 2012 ISF am interested in installing Swift Springs with Bilstein B6 Dampers. Looking at the Swift springs there are two distinctive Part Numbers (PN) for the different ISF Model years. The 2008-2011 ISF uses PN 4T906 and the 2012+ ISF uses PN 4T910. My understanding is that the difference between the springs is that the on the 2012+ the diameter of the shock perch side of the spring is smaller than on the 2088-2011 springs. The Bilstein B6 Dampers have only on part number for all ISF model years they are 24-155311 Front Left, 24-155328 Front Right and 24-155335 Rear Left and Right. Will the Bilstein perch work with both styles of springs, the 2008-2011 and the 2012+? If not, is the best option to purchase the 2008-2011 Swift springs and Install them with the Bilstein B6 dampers? Will his combination work in a 2012+ ISF with no issues? or are there other differences? If this topic has already been covered I apologize, but I could not find this information in any of the previous Bilstein/Swift threads. Thanks in advance for the information.

shocks will work on all year models, as far as the spring they are different after 12+

Thanks for the reply man I appreciate the info. After reading a bit more I think I may go for the BC coilovers with swift springs.

Hi,

I ended up going with KW coil overs. I have had them about 9 months and so far, not regrets.

Thanks,

Caleb
