This needs the ability to be much softer than the Gendron rear bar, probably softer than the miata bar. If the design uses universal center sections as your front bar does, this shouldn't be a problem.

 

If you calculate the rates, softer than the Miata bar and small Gendron rear bar is next to nothing in light of the geometry. I just disconnect the bar at that point. I like the Kacepts because of the careful to detail/quality. If I didnt already own the Gendrons and Comptech, I would purchase one!

 

Yes, the small Gendron rear.

 

Personally, I agree with this, as how it suits my driving and setup, and since the Gendron rear targets a stiffer range, I will make the Karcepts rear bar start at a point definitely softer than the Miata and then make the range sweep as high as possible from there.

 

Estimated price?

 

Aiming for as cost effective as possible... Most likely somewhere around $350. Will plan to offer a combo with front + rear for under $1k.

 

Awesome!

Since the coils came with a square setup instead of being heavier in the front what sway bar setting should i try out? Current weights of the bar are 1-566 lbs, 2-644 lbs, 3-739. People mentioned that i could compensate the lighter front springs with a heavier bar setting but i don't have want to under steer the car too much. I can also play with rebound and compression, but any thoughts would be appreciated.

Here are some weight breakdowns:

OEM 295
Moddictions 1-566
Moddictions 2-644
Moddictions 3-739
Gendron 1.25 1-367
Gendron 1.25 2-389
Gendron 1.25 3-399
Gendron 1.25 4-477
Gendron 1.25 5-526
Gendron 1.25 6-582

 

I'd like to know where the posted rates for the Saner/Modiction bar are comming from.
I've seen the following posted:
S-566 lbs/in
m-644
H-739
When I use Phun formula with .7 front Motion ratio and .67 rear I get:
S 823 lbs/in
m 959
h 1107
Anyone have some input on this?
Thanks

 

The Phun formula assumes the endlink is fully vertical, but we know that this is not true for all settings. So your calculations are probably high, at least at the stiffer settings.
