Yeah that is something I will have to keep an eye on. No great alternatives right now.The problem with the GT350 ducting is that the wheel blocks flow under steering input during trail braking. Your ducts are further inboard and that will reduce the effect. It's not a huge issue on the 350 OE brakes because of the high mass of the rotor (30 lb) and it's physical size makes it a big target for non-directed flow. But when I went with the (smaller, lighter) AP Brakes and stock cooling, I averaged only 5 hours on front pads and 7 hours on Rotors with 350 cooling. Adding directed cooling to the inner rotor vanes more than doubled rotor life and increased pad life by 50%.
It used to be on the Cortex site, I always like the simplicity of that design.The SLA is on the website for sure, in two flavors. The bar is not there as that is “made to order”. The really nice thing about it is it adjusts with quick release pins. Very fast adjustment.
