Default 924 Strut Assembly on a 86 951

Hey guys just have a quick question. Can the 924 or 931 Strut Assembly work on the early (86) 944 Turbo? I know the early 944 sets will fit on an 86 Turbo. Thanks for your help!

nope- no early stuff- you need 87+ to work on a turbo/s2/968- i have a used set of 87 n/a struts if you need them.

Interesting.. I thought the 86 Turbos had slightly different set ups considering they also have the early offsets. I know the early A-arms fit the 1986 Turbo with the caster clips. I was just looking to remove my M474 suspension but it looks like it may be best to just cut a strut.

It's the strut flange that will be wrong. The spindles are different on the 86na and 86t. Yes your early arms will fit an 86t or 86na but the struts will only fit the 86na due to the change in flange measurements on the 86t.

Been discussed before and the general concensus is the doing it this way you are weakening the strut at it's most stressed point (the top flange bolt). Then to make it even more stressed you are adding more weight in the form of 86t discs and wheels to the already weakened area. Could that be the reason Porsche changed the struts/spindle bolt spacing for the 86t? My guess is yes.

IMO Best/safest way is doing it the way Porsche designed and use the 86t struts.

Maybe you can tell me why Porsche made the 86T spindles the weakest out of the entire range of cars. Maybe you can also tell me why they put a turbo under the intake manifold. I can go on about the ill "designing" by Porsche on these cars. All I know is that I did not notice a difference in strength when drilling out the holes. It's a cast hub sandwiched by two layers of metal on each side, with a bolt in tension and fully yielding the diameter of the bolt head and washer. The lower mount bolt is unmodified. I would not have done it if I thought it was going to be weak. If an actual engineer wants to roll in here and tell me that I am going to die from this modification, then I might just change it. Until then, I am going to run it. At the damper and spring rates that I am currently running, I am not worried one bit about that drilled out eccentric hole.
Cool, I admire your ingenuity. But why get so aggressive? This is a discussion board, we discus stuff, and I was simply giving you the consensus from past discussions. It's not the law, do as you see fit.

Hey Rob you happen to have a pic of your drill modification to the strut? I might try this, since you and others have had success.
