I am about to pull the trigger on a 911 front suspension. It is billed as being from a 72-74 911S (no the aluminum calipers are gone and I will be using regular A calipers instead) as it has KONI struts with the 3.5” spacing. Ultimately I am looking to install KONI Sport (aka Yellow) struts that have the adjustment knob on the top. I have read a few quality threads such as…
http://www.914world.com/bbs2/index.php?sho...c=390&st=20 This answers a lot of questions, but that thread mostly talks about Boge struts, spindle mods, etc. and doesn’t 100% clear up a question I have about KONI insert compatibility. My confusion comes from the KONI application guide http://www.koni-na.com/pdfcatalogs/2007applguide.pdf (approx 1 MB PDF). If you don’t want to look at the PDF here is a summary of the KONI document … 65-68 911 Boge strut 86-1394 Classic KONI strut 86-1308 Classic 69-74 911 Boge strut 8641-1039 Classic KONI strut 86-1638 Classic 75-89 911 Boge strut 8641-1039 Special KONI strut 86-1942 Special (footnote) 8641-1039 Sport 914 and 914/6 All (Boge?) 8641-1077 Sport To translate KONI types, Classic = “Black”, Special = “Red” and Sport = “Yellow”. The implication is that "it appears" that you are really limited if you want to use the “Sport” insert as they only list the “Sport” strut for the 914 and 914/6 as well as for the 75-89 911 (but with a cryptic footnote). The 911 footnote says… “Ext. adjust Sport alternative (both Boge and KONI) for OE KONI struts, gland nut 73.25.01.011.1 must be ordered separately” My confusion/questions…
One last thing… I have tried to document everything that I have learned on the 914 Wiki. Please feel free to look at that article and if you think you know what you are talking about, correct any mistakes. http://www.roadglue.com/wiki/index.php/911_front_suspension |

Eric, thanks for jumping in! (IMG:style_emoticons/default/biggrin.gif)
The photos of the KONI strut is interesting. You mention (and the photo shows) that they have a flare, but the Boge does not. Implication here is that the Boge strut has a smaller diameter than the KONI strut?? I wonder if this is some evidence toward my idea that the KONI insert that is designed to fit the more common Boge strut have a smaller diameter (same size as Boge OEM insert?) than the direct replacement KONI inserts for KONI struts. So if you wanted to use a Boge "style" insert (of which there seems to be more options available even from KONI) in a KONI strut, you would use the special gland nut they mention? Where I am going with this if my posts are not clear enough is that I would like to be able to use the KONI strut, use the special gland nut and then use the 914 KONI Sport insert that is already valved for the 914, but is intended to be used in a Boge strut. I am making a LOT of assumptions here which might be really wrong. |
