Couple of questions about lowering my 2014 991 C4S Coupe. I am a DIY'er, and have the appropriate H&R Sport Springs for my '14 C4S coupe. I've lowered cars before, but not a 991 and not an all-wheel-drive car.

I am looking at the shop manual for Porsche 991 front spring/strut removal, and they instruct that for an all-wheel drive vehicle (like mine) "before raising vehicle, loosen the drive shaft mounting on the wheel side - get a second person to assist by operating the brake." I am not familiar with this at all. I don't think this is necessary, but thought you might be able to advise?

Also, another question about the instructions - After removing the wheel, the instructions specific to all-wheel-drive cars refer to "carefully press the drive shaft journal out of the wheel hub until the shaft can be moved by hand." There is reference to using a puller tool with pull stud to do this. Again, I don't think this is necessary, but on all-wheel drive cars maybe so?

Really appreciate any help to be offered??

Happy New Year!

 

Not sure why you seek to skip steps the factory manual lists.

Why not just follow the steps and let someone else use his car for a guinea pig?

 

Thanks Macster - appreciate the comment but I was looking for something a bit more helpful... I probably should have phrased my questions better. What I am really asking is the how rather than the what specific to the C4 AWD steps mentioned in the manual... As I am swapping springs only others have suggested that I don't need to actually remove the struts at all, but merely need to lower the strut far enough to remove the camber plate and then pull the spring out through the hole. The Porsche shop manual is for strut and spring removal and basically has you disassemble all suspension and brake components. As far as I know Porsche doesn't have official instructions for swapping springs with aftermarket.
So anyways I am able to get the wheel carrier to drop a bit, but appears that the front drive shaft may be prohibiting the wheel carrier assembly and strut/spring assembly from dropping far enough so that I can get the top of the strut with PASM cable past the camber plate. I'm talking within maybe 15mm.... So close yet so far!

So I am hopeful that an expert in this technical forum may have done this before and or can offer advice. I mean I know people have lowered C4s before me, so please help a guy out as he wants to learn? :-)

Thanks in advance!
