No, the rotors are much larger on the IS350 than they are on the IS250.

So it is worth upgrading it to IS350 ? Any significant difference ?

^I'd assume it's mainly for looks and improved brake pedal feel.


Going to get a shop to do this. If I don't want to cut the dust shield, is this the complete assembly of parts that I need to acquire?

IS350 Calipers
IS350 Rotors
Brake Pads
Dust Shield

-Not sure what the Fit Kit Hardware is. Would a shop typically have this on hand? Is this specific to this brake upgrade?
-When buying the calipers, I just need to ensure it comes with everything intact including the retention pin & shims?

The fit kit is specific to this brake upgrade. It's the clips and pins required to hold the pads in the caliper. Unless your calipers come with this. Some aftermarket remanufactured calipers do.

I did this upgrade on my g35 because the newer dual piston brakes did not dust or warp the rotors prematurely.

Do the dual piston is350 front calipers dust as quickly as the is250 front calipers?

Also, what year is350 front calipers should I be looking for?

The IS250 and IS350 both used the same pad material, which (for certain years/countries) do tend to dust a lot. That said, due to the design of the IS350 calipers, I find more dust hits the wheels and they tend to dust more than with the IS250 calipers, both using the same pads.

If you're looking to reduce the amount of visible brake dust, get different pads. Whether you change the calipers or not, get different pads if dust is a concern for you.

Great Post. I had a quick question about the front calipers tho. The mounting holes for the front 4 piston caliper dont quite match the mounting holes for the single piston caliper that the car comes with based on the pictures. so did you have to get any kind of mounting bracket for the front or did they got on the factory hub without a problem?

The mounting holes are the same. No mounting bracket or modifications are required.

On my 2014 IS250 F-sport I got from rockauto.com, a set of drilled rotors, calipers and pads for a 2015 IS350 for about $500. No modifications needed just push back the dust cover shield.I will post a ending result pic, good luck.

Purchased a set of front and rear calipers off a 07 IS350. I was taking them apart to start prepping them for powder coating when I noticed one of the rear calipers is somewhat seized. I was able to able to expand the caliper all they way outward with a C clamp, however I have not been able to push the caliper inward. This project just got complicated -__-
