On of the Nator NYC members introduced this to me over 4 years ago and when I installed it...talking about great added cornering of course install and the other components from CS.
Is it possible to make one for the 2004-2009 Mazda 3s sedan model? PLEEEEAAAASSEE?!
Any Chance of Offering the 4 piece rear chassie Brace again? That was a sick setup, and please if your not offering it anymore, why not?

CorkSport Reply:The 4 bar setup has sold out of stock and we are not offering it anymore. Demand for the kit was low.
If this is the same bar as the set comes with could you not still use it on sedan because the set can be used for a sedan which a little more work to it?

CorkSport Reply:The chassis structure in the rear is different between the hatch and sedans. We have had people install the bar but it does require some work beyond the installation instructions.
will there be one for the sedan model?

CorkSport Reply:We have no plans to.
This brace is well made, perfect fit, adjustable and probably the most noticeable upgrade to my 3. Car rides much with much less flex on all the twists and turns on my commute. Would highly recommend if you're even contemplating this purchase. You will not be disappointed.
Great product! Feels very solid, less roll/flex and is easy to remove if needed! Installation was easy.

How tight do you twist the bar, and the securing nuts? I'm guessing they need to be pretty tight so the bar is applying some force to the brackets.

Hi guys! How easy is it to remove? I mean aren't you supposed to torque it so that it's locked in place strong and not just hangs on the pins? And if it's torqued - how do you pull it out without untwisting the nuts first? I'm really interested in the part, but I use my trunk a lot and it's kinda important question for me. Thanks!

Do you an updated version of the install for the rear hatch/chassis bar? The link currently takes you to instructions for the old 4 bar design.
