Well, that's generally what anyone cares about for street use, so yeah.

"felt" sure... lots of things can change the feel of the brake system without actually impacting the measurable stopping of the car. (the high dust vs. low dust brake pads are a good example... car stops in exactly the same distance with either but the high dust ones feel a lot more grabby)

In regards to "braking performance" that would depend on your definition of it.

For normal street use? No... because the only measurable "performance" that would matter to anyone there is braking distance.

For track use (or possibly severe mountain driving where for some reason one refuses to use the paddles correctly despite it being one of the few times they're genuinely useful) then quite possibly it could make a difference in thermal management, but it still wouldn't ever let the car stop any shorter than it does the first time with OEM parts on it.

We'll be working with the IS350 AWD brake set-up shortly to determine fitment to the IS250 AWD.

sounds good as an alternative option but like i said in my earlier post. the current is350 rwd bbk already fits and has been done on a is250 awd. so it is confirmed to work with all of the hardware replaced.

Well, phooey! I guess we (its me) stand corrected. I'd like to verify it for myself but I don't have any AWD's in the shop at the moment to run a 350 caliper out there for fitment. After looking at the various parts involved with the kit again, I can't see any reason it would not work, but that darn wheel hub and spindle just has me confused because it's huge difference in size and shape. I've been wrong before!

Thanks for the follow-up everyone. I'll make the appropriate changes to the kit we're offering. I've also changed the pricing again as well. Just 599 for the brakes, 797 for the complete brakes with rotors.

Thanks again,
Darrel
