Yeah, you already have a 24mm front sway bar.

The Comptech setup is good. It incorporates the reinforcement kit, rear lower tie bar, and 22mm rear sway bar. It's also adjustable for stiffness. I think it costs somewhere in the neighborhood of $360? It might be cheaper though to get an OEM ITR sway, the BSQ kit and some other brand of rear lower tie bar (like Neuspeed). I would imagine doing it this way would cost you about $70 + $30 + $80 = $180, so you can see there's a major price difference. IMO the adjustability of the Comptech isn't that useful in your setup unless you get drastically stiffer springs in the rear, requiring you to loosen the back and add more understeer. If I had it I'd just leave it at the highest stiffness, like a regular sway bar. This is assuming you're trying to achieve neutral handling.
