Koni yellows for our application are the same as the non-ST version, as verified by Lee Grimes with Koni NA The only difference is that there's a removable rubber insulator on the base of the spring perch that needs to be removed on the yellows to be used with the ST. Also, the ST uses a couple removable harmonic dampers bolted to the struts, and the Konis have no provision to retain these, but it creates ZERO issue.
The needed part numbers are as follows:
(2) 8040-1419 (rears)
(1) 8741-1565L
(1) 8741-1565R
Tirerack doesn't have them listed for ANY application, but per email/phone call, their price is not competitive anyway. Best I've found so far is though LTB Autosports Inc. out of Florida.
www.LTBautosports.com or
sales@ltbautosports.com. The owner's name is Louis, and he is a SUPER helpful and prompt guy! My shipped price was $798 and was the best I found anywhere!
