I thought I'd give this a little bit of an update. I recently took my shocks up to Fortune to get them rebuilt for some Swift springs. I went from a 9k/7k set up to a 10k/9k set up. I haven't been able to drive on them yet, I just got them on the car tonight and its raining until Saturday.
As you can see the front swift springs are 1" shorter then my old ones:
The car on the ground:
If you were running anything other then OEM aero this height just wouldn't be possible. I can't even get my finger under the lowest parts of the side skirt:
As you can see the front fender (which has been flared and therefore the edge of it is up higher then a stock fender) is ~22.5" off the ground. The Fender is resting right on the tire at this point.
A side shot:
If you had a stock fender beam the tire would be resting on it for sure. I have about 1-1.5" of clearance and I have shortened mine by ~2".
Here's my shock dyno, it got a little damaged in shipping, but you can clearly see the digressive compression curve on the top part of the dyno - this is something no other coilovers have in this price range.
Terry at Fortune made a video of the rebuild process, and outlined what they do and why its so special:
I will be sure to update the thread with my thoughts on the springs/rebuild after I drive on them.
