Fluid, if the drop only ends up being 0.5" I wouldn't see that as a bad thing. The konis already lower the car 0.5", and another 0.5" drop or so would be just about perfect.

Thought
Fluid:
If there is a physical limitation in the rear you are dealing with that will only get you to 260, maybe we can back off the rate on the front a little also. I want (More than anything) to have a well balanced car at the end of this.
Thanks.

Either way, as long as the final production spring rates are in this ballpark, we can always fine-tune the handling balance with swaybars, tire pressures, alignment, etc.

darn I was hoping for something in between the current Tein S-Tech and the now offered Auto X spring rates. Say 300/200 ish with a deeper drop for the street spec.
What made you feel we needed another very similar profile street spec to the already existing s-tech/GF210's in the market? What makes the street spec springs any different/better?

Brice,
1. When will the Autox/track springs be available?
2. Any chance of putting a group buy together for the first shipment of track springs? I know there are several guys on here (including me) who are interested. Maybe a "beta tester" special price break?

I will have two prototype springs that are going to go for $285 I have one customer that is near confirmed. If you want to be the other let me know.
This prototype is going to be the exact same as the production run.
There will be 50 units that I will need to purchase so the faster I can fill the list up and get some payments in the sooner I can get the ball rolling on this.
I will start a group buy after the 2 spots for the Prototype springs are filled.

And because most will be using Koni Yellow's we have changed the Drop of the spring so the end user will not experience a higher than desired drop.
The New Drop is
Front: -0.8 inches
Rear: -0.5 inches
When coupled with the Koni drop I think this would put the car at a sweet spot.
