Ordered by TRE who is doing the work on the car. I just sent in a big check but think parts alone were around $5k ...tax and shipping but no installation.
Those look interesting, but not a lot of information on their site specific to the 964.
They at least say they have an application for it, but not for what years, C2 or C4.
Did you buy a set of the JRZ's? Their site doesn't have any info on prices. I guess you have to go through a distributor?

So, I started my installation of these great looking coilovers and have a question.

After preloading the spring, how do I determine the overall length of the shock to give a specific ride hight?
Here is a picture of the stock and Godspeed coilover setup for comparison.

In all of the coil overs that I've ever used, the ride hight is adjusted by raising or lowering one of the spring perches. In Godspeed's case, you adjust it NOT from the spring perch, but by adjusting the bottom mount of the strut.
This is odd to me, but do-able. But I imagine makes it impossible to make adjustments at the track.
If any of you have installed this, can you tell me how long you made the assembly before installing it into the car?
I'm hoping I don't have to pick a length, then put it in, drop the car down on its wheels, determine that it doesn't suit me, then have to take it all apart again to adjust once more. I want to avoid that.
Thanks!

I don't have these, but I would set somewhere in the middle, or little lower depending on how you want your car to be. But, in theory, springs 'should' settle and change the height a bit anyway. I'd set the middle, ride around for atleast 500 miles then re-adjust and alignment.

Mr Alex, that's what I'd normally do. As far as spring settling that's what I'd expect too.
But regarding the initial setting....there's no easy way to determine what is a mid setting.
When comparing these to the stock coil over in the front, these are much much shorter. About 2 inches shorter on full extension.
What I ended up doing is coming up and a system where I just screwed it all the way down to full extended and measured it, then screwed it back up to fully short. The travel amounted to about 4 inches.
I shot for the middle which turned out to be about 9 inches when measured from the bottom of the spring perch to the bottom of the shock. This turned out to be too tall.
So, undid the bottom leaving the top in place and screwed the bottom up to about 8 inches. This was better but not good enough.
I finally set it to totally screwed to the top which is 7.5 inches. This turned out to be nearly perfect. I think I can dial in a little more once the springs settle by adjusting the spring pre-loading.
Here is a picture of the front with the Godspeed coils at its shortest where the spring is pretensioned by one turn.

Another with the stock rear shocks still in.....massive rake!

Now on to the rears!

i have a few non stock items on my 964.
msd coils
five o motorsport injectors
pbr ceramic brake pads
alpine stereo deck
so... willing to try lesser expensive items esp. when i am not trying to shave 2 tenths of a second off my lap time... and no concourse winner either...

I've had the Godspeed Coilovers on now for probably 12 months, about 4000 miles - UK roads / motorways.
The units themselves still look like new - no issues at all.
Ride - I tried, (ONCE!) to have them on something other than the soft setting, and within about a mile, stopped and put them back to where they were. UK roads around me are not really up to much and they crashed and banged a little. Motorway travel and it might be better.
Not been tracked - although handling seems balanced and precise.
But I'm not a racing driver.... just like to go out for a ride :-)
