Hi have quick question

Will 2008 IS350 Rotors and Calipers fit the 2008 IS250? As in direct bolt up?
I Think the IS350 rotors and calipers are larger as in double piston.

Thanks for the link. Just had a few more questions.
1. If i purchase the IS350 rotors/calipers new, will the dust shields that go along with those work or is it better to go with the oversized ones. Also can i just change the fronts only and leave the rears ? Are the IS350 rear rotors vented ?

I didn't replace my dust shields on my IS 250 when I swapped 350 calipers and rotors on. You will have to hammer/bend/cut the shields for rotor clearance. Yes, you can change just the fronts if you want, doesn't make a difference since the weight and power of the car is the same. Not sure if the rear's are vented, don't remember, haven't had to work on my brakes since I did the swap.

So clearancing the 250 dustshields isn't that big of a deal, but I ended up taking the fronts completely off when I couldn't get them to not scrape the rotor at speed. Rears still will on occasion, but rarely enough to notice. I will be, at some point, installing the appropriate sized shields, since they're actually fairly well designed at helping cool the rotor surface.

Before swapping, I was unable to get PS AS3+'s to activate ABS without the road being wet. After the swap, a good pedal stand will massage your foot.

As an aside, I bet the cheapest 6-pot Brembos you find on Ebay from Cayennes and Touaregs can be adapted fairly easily, and Mustang 350mm rotors can be used to make a poor man's F-sport kit.
