I just replaced my front inserts with Bilsteins. I had no idea what inserts were in the struts but, the PO sold me the car with KYB's on the rear and 50 series tires all around. My ride was HARD until I switched to the Bilsteins. Kill Your Back is right, along with other parts of your anatomy! I only changed the fronts but, the ride is MUCH better. DO NOT USE KYB!
Depending what struts you have in front (part #) will determine what options you will have to work with. Maybe. I say maybe because I could not find my strut p/n anywhere online. I still don't know what car my struts originally came on. I took a chance and bought the struts for the closest similarity I could find to my p/n.
Good Luck!
Oh yeah, for those that still debate whether to put oil in the strut tube, my drivers side had oil and the passenger side was dry.
I agree with the NON use of KYB's ,I also have discovered to my dismay that 914 strut housings ( espeically 73 &74 ) have holes in the bottom where the balljoint pin sticks up into , basically what ever fluid you use in the housing to cool the insert will eventually leak out . The 911 struts that I have delt with , 911T '70 , 911 later '89 have no hole in bottom , not sure of other years , but the point is 914 strut housings have holes in the bottoms= Leaky.
