First off, it's my first post :^)
I've tried to do a search on the forums about the topic, but I couldn't really find a thread that answered my question.

I have a 2015 IS250 F sport, but I've been really digging the front bumper of the newer (2017+) IS F sports. I've just gotten into modifying cars, so I'm not particularly familiar with fitments and the like. If I were able to get my hands on the newer F sport bumper, would there be a substantial difference that would make installation difficult?

 

welcome to the forums.

For your question,
you will also need to change the headlamps if you want the 2017+ bumper and grill.
Headlamp wiring is also changed so difficulty there to make some wiring adjustment to get everything in working order.

 

in addition to the bumper you need the 17+ hood, fenders, and as Spec as mentioned, headlights

 

There was no change in the Hood and Fenders in 2017.
It remains the same just like 2014-2016 year models

Good read if you are bored.

Interesting
That's a lot more work than I anticipated.. I'll probably just keep the thought in my head once all the important changes are done haha
Thanks guys!
