do i have the right struts?

Recommended Posts

Hi all, Ive been working with a suspension vendor to get a set of re-valved Koni Yellows. they sent me struts that appeared to be fine. I intend on using the stock springs and compensation disks with the Konis so that i dont have a ride height issue/imbalance (ive heard about some nasty tolerance issues with H&R springs, but i guess thats just the nature of working with an anal retentive suspension engineer). He calls his contact at Koni up, they work things out and i get a fresh set of yellows. i was changing brake fluid and broke out one of the struts just to see whats what for the install (not installing till spring, might as well beat up whats in place over the winter), and i notice there is no provision for the sway bar end link on the lower spring perch of the front strut. the rears look fine on the yellows, they have that cup where the rear end link bolts in to. but the fronts have no provision on the lower perch. i dig around online for pictures, and i keep seeing replacement struts that have no provision for the end link. im not the first owner of the car, and i have no info on mods. i called my vendor, and he inquires if its possible that i have a gt3/rs/gt2 suspension installed? well i dunno, do i? please see the attached pics. if this is in fact a stock suspension, what do i have to do in order to attach the factory end links to the yellows (ie, when i coordinated with the vendor, i told him its a c4s, same as a 911 turbo for cross reference)? should i ask him to cross reference with the 911 C4 instead of the turbo? do i have to go aftermarket end links (i didnt want anything aftermarket becuase i drive my car 4 seasons in New England, and i dont want spherical ends getting all rusty and noisy)? sorry the photo isnt rotated. if there is a serious issue here, could i have my suspension guy knock off the koni lower perch, and swap in the factory lower perch? I REALLY dont want to go down that road, to many opportunities for errors in alignment, and breakage. my car is a 2002 911 C4S (6spd).

C4S and Turbo (both widebody cars) share the same suspension design/fit. Spring rate are likely different due to weight differences but physically turbo parts will fit a C4S perfectly.

and that was my approach, yet koni (not my vendor) sent over a pair of allegedly stock 911 turbo fitting struts... so where do the end links go?
