I bought a set of these last week on EBay in the hope that I can use them with Koni FSD's which aren't available for the early 964's. I haven't tried them yet so can't give a definitive answer.

Chris Franklin @ Center Gravity here in the UK adapted Rennline mono ball top mounts to fit Koni FSD to my 1989 964. Brilliant set up. They are so helpful and friendly, turned my car ,which was dangerous at any speed on a bumpy road, into sublime, compliant, safe fast car! All the of the above is of course fairly academic if you're in the states.

Good to know. I am wary of going the KW or Bilstein route as I don't want a crippling ride and FSD's seemed to be a good compromise.

Thanks for the feedback guys.

Looks like my 4x4 days are numbered. Can't wait to feel the car drive like it was designed to drive.

+1 Looks like I'll be just behind you. Also thanks for confirming it's a real product.

I've narrowed my suspension choice to either Bilstein B6 HDs with HR green/purple springs. Or something from Koni.

Is the FSD damper a better shock than the Koni Sports (better quality, better damping)? With the FSD shock, it looks like the damping is pre-set and built-in - maybe this is a better quality design. Are they softer than Koni sports dampers? Koni sports have an adjustment **** at the top of the shock, but I'm sure it a set it and forget it thing...

Koni categorizes FSD dampers as "performance" and Koni Sport dampers as "sport and tuning". Maybe I'm reading too much into that...

It looks like neither Koni has a threaded perch to adjust ride height? Is this true?
Bilstein HDs have threads, that alone may be reason enough for me to go with the Bilsteins...

I don't want anything harsh either, just better quality motion control.

In the end it seems like there is little real world difference between either Bilstein HD B6 (with HR green/purple springs) or Koni FSD with Eibach springs.

Would love to hear any feedback.

From what I read the FSD's must be used with the OEM springs and not aftermarket lowering models. Obviously a drawback if you want a stance change.

I've used my FSD,s with Eibach Pro springs. Ride hight is RS + 5mm. Absolutely no problems.

Most of the ads I read say they must be used with standard springs which is a pain as finding new ones is hard. Good to know it's not true.

Koni FSD's can be used with lowering springs as long as they don't excessively lower the car such that it rides on the bump rubbers with frequency. The Eibach Pro Kit springs work perfectly with FSD and Koni actually packages them together for the 1145 kits.

Unfortunately, measuring bump and rebound travel is something that not even "pro" shops will bother to check, let alone 99.9% of anyone going after the lowered "look".

Jason @ Paragon Products

Stick with the Eibach Pro Kit springs and you'll be fine.

Are they Koni sport dampers rather than FSD? I am asking from a position of almost complete ignorance with this, I'm just trying to avoid making mistakes when I do this.

Jason @ Paragon Products

Yes sir, the 1145 kits do use the Koni Sport Yellow shocks but the springs included are the Eibach Pro Kit springs which work well with FSD as well.

ALSPEAKE

I can confirm they work perfectly well with Eibach Pro springs.

Has anyone had issues with these types of adapters above? I've only found them on Ebay. They do not seem too complicated, but curious if folks have had success with them to use shocks designed for the later model 964s? Really opens up options for us with the earlier cars.
