I've had OEM 350, Rotora, and F-Sport currently. They all work the same. Pick which one you like best for looks OP

 

anyone have any idea if the f sport brakes can fit the is 300

 

Based on your profile, I assume you are referring to the 1st generation Altezza/IS, in which case, no they are not a direct fit.

yes

thanks for the reply. and yes i am talking about the 1st gen i wondering if there is a way to modify them to fit

 

Got a few question/problems:
1) I am having rattling in my front passenger brake. It's a light rattling over uneven surfaces. I did some research and seems like some aftermarket pads rattle. Anyone has/had this problem? I have Akebono front pads. I didn't have this rattling before doing the swap and I'm sure nothing is loose on the caliper because I double checked the torque specs on the bolts holding the calipers to the knuckle. I am using the OEM pin and metal clip for the front as well.

2) Is this normal? Seems like the rear pad doesn't cover the entire rear rotor (Stoptech). I went to autozone thinking the IS350 pads were bigger than the IS250 but they said it's the same part. I am reusing my rear IS250 pads. Are there bigger aftermarket rear brake pads?

 

1. I have only used Lexus pads, but haven't experienced any rattling or odd noises of any kind.
2. Yes, that is normal for the pad contact area for the rear.
