If you've seen the swaybar, and where it goes, you'll understand his point. It's not cocksports problem, it's actually an issue with the mazda setup
If this is in fact the case, it is absolutely corksports problem. the factory sway bar doesn't bang the car if you're lowered... only corksports does. They need to at least clarify (that you can't go to the stiff mode), if not fix this.
In any case, I know CS tests their products, and I'm sure they tested this bar with their lowering springs. They went through the trouble of making and including billet brackets, if the endlinks were known to be a problem, they would have made and included those as well... Right?!
EDIT (after reading the above post). I'm coming across sounding like a jerk, and I'm not meaning too. I'm genuinely speaking from past experience, and from future necessity... I'm looking to order sway bars soon.
Here's my deal. Lowering springs aren't custom. There may be 5 brands available (other cars have 50 brands available), but the ride height is all within what, 1" form each other?! You're speak like we're custom welding rock-crawler suspension here or notching frames and running bags. Aftermarket sway bars should work with aftermarket springs. Period. Custom setups are different. Standard, off-the-shelf, lowering springs, are all standard enough.
My point will always come back to simply this: if Corksports rear sway bar doesn't work with Corksports lowering springs... they've failed.
The most simple solution (if this is all accurate) is that Corksport should make and offer adjustable end links. Throw in a note (on their website) saying they're required to run this swaybar with lowering springs, and boom. Done.
