Ok let's start a list of who's interested, consider this a pre-buy since they are going to be produced anyway...

Intro price will be $260+ship

Installation:
1. cutting strut tube
2. drill a hole in the bottom
3. clean everything thoroughly with acetone or other potent solvent
4. installing the adapter oriented correctly with panelbond or equivalent glue
5. torque bolt with stainless spacer underneath to 150ft-lbs, locktite recommended

Requires:
1. almost any front s13 coilover or other coilover with s13 lower bracket
2. suitable 240Z top hat for coilover (or universal)

*** I will be producing a batch of stepped washers to use s14 brackets on s13 spindles or this adapter for extra cost...

Benefits:
1. will allow up to 9 degrees of camber adjustment depending on coilover bracket
2. doesn't require camber plates
3. has set screw on adapter to mark camber locations for disassembly
4. pre-set screws can be made for quick road or track alignments
5. lightweight aluminum body, stainless lower plate, oversized retaining bolt, approx. 700grams total
6. adds up to 1.5" of backspacing depending on wheel used
7. allows really wide wheels

Couple of stupid questions.
Is the hole at the bottom to be the diameter of the adapter of just the diameter of the through bolt?
Is there a machined "shoulder" at the top to prevent the adapter from falling through the hole?
Is the "shoulder" and or the bottom plate have a machined serration to prevent rotation?
Why bond it?
Could also drill a hole in the side for a set screw to prevent rotation. I'm sorry I just don't like the idea of gluing parts, either they are welded or serviceable, glue is just an unhappy medium for me.

The main discussion thread for this is actually here: http://forums.hybridz.org/topic/119399- ... s-bolt-on/

But to quickly answer, the hole in the bottom is only for the M20 bolt, there's a stainless sandwich plate that gives the head something nice and level to sit on, the bottom of the strut tube is convex when seen from underneath.

The glue is backup and corrosion protection, that step was included when the adapter material was changed to aluminum instead of the regular steel to save weight. I'm sure you don't want the dissimilar metals eating each other do you?

I have an account there that predates my account here by about 8 years. We can't just defer a conversation from our site to theirs just because there is a similar discussion. Just as you took the time and made the effort to advertise your wares on multiple forums because you know not everyone is on every site. Should you not address all questions and concerns from all the forums?

You're taking it entirely the wrong way, I am advertizing it where I can, and taking questions anywhere people ask... for people that do have an account there, it saves them the trouble of asking here if it's already answered.

Now, did you have any other stupid questions? :)
