Hi, I've got a 2004 996 turbo, 69k, and am giving it a suspension refresh.
I've decided to put Bilstein B6 shocks on, which I've been advised is a tidy, easy small upgrade, in place of B4s which I understand are standard.
At the moment I'm doing the rear, it'll be front next, so maybe more questions then, but...
1. Am I right in thinking my old springs will fit on the B6 without problem, or do I need new springs?
2. Is it a false economy not to buy new springs anyway? My original rear ones seem fine with just a tiny bit of corrosion at the base, which should clean up.
3. Is it also a false economy not to buy new top mounts? The fronts are worn and will be replaced but the rears look okay. Maybe it's daft not to change them though while I'm in there doing the job. (And are the Hamburg Tech ones any good? Or stick with OEM?)
4. Is it a must to replace the hardware - hexagon top nut, washer etc? I know some parts like these are sacrificial. But for eg. the top nut is only circa £2, so again, daft not to right?
I'm replacing the ARB droplinks too, and will probably fit new ARB bushes while there.
Is it worth going polyurethane eg Powerflex if all the other bushes on the car are standard? Or should I not bother?
I'm going to replace the coffin arm and lower control arm, although I've been told you can get the bushes refreshed on your original arms by sending them off to some places.
Grateful for any advice.
Thanks,
Will
