I'll try to answer a couple questions, as I don't have much time to write...
-It's not absolutely necessary to move the battery, but it makes it better if you do... Cable length is just part of. Under the battery lies a great attachment point for the clam...
-Weight: It will be very light...
-We will "kit" this and make it available for sale. The final unit, like all our projects will be laser or water jet cut, p-coated, with high quality hardware...
-I'm quite certain that this will not work unless you have eliminated your rear panel. If you're wondering why, then just check out how many fasteners attach your rear panel to the clam
Don't go out and buy a rear panel elim kit to prepare though, as it will take a special unit to work with the flip-top lid...
-Will work with any exhaust as far as I can tell... but no guarantees...
- It will be pretty expensive. There's a lot to this kit, special fasteners, complicated hinge system (4 bar hinge), battery relocation, etc...
A couple things that I found about the Hypersport hinged clam. It doesn't hinge unless the wheels are off the car! It's super easy to make a hinge that works with the wheels off. If you look at any pic you see with their red elise at the track, they always remove the clam to work on it, not flip the lid. THe only pic where you can see their clam in action and tilting, there are no wheels on the car... There's nothing easy about making a hinge that is BOTH out of sight while the clam is the normal driving position and allow the clam to tilt with the wheels on the car... Finally, after the hinge work is done, there's the issue of attaching the clam back to the car well enough that you don't have anymore body flex than you had before...Also not easy...doable, but not easy...
I need to run. I'll try to get pics up when I can...
Best,
Phil
