Default 2018 Lexus IS exterior difference compared to 2017 model

Hello,

I recently bought a 2018 Lexus IS300 and would like to know if there are any difference in the exterior of the trunk compared to the 2017 model.

I would like to know as I am thinking of purchasing a lip spoiler for my car off Ebay and they only offer lip spoilers that fits up to the 2017 model IS.

But the tail light housing is deeper from 2017 and up. I' saying this because I purchased a 2014 and up carbon fiber trunk from seibon and my tail lights did not fit. The 2014 to 2016 trunk housing is is too shallow to house the 2017 and up tail lights. Also if you are getting coil overs the front struts changed in the 2017 and up is f sport and the lower control arm is aluminum and different as well. I just bought ksport coil overs that were supposed to fit 2014 and up lexus IS. Still waiting on replies from other members if gs or rc struts fit. The are identical to our new front struts.

The first pic is the bottom part of my front shock from my 2017 is350 f sport. Other pic is of the k sport coil over front shock. The are different. I noticed the 2013 and up gs350 f sport front shocks look like mine but waiting to see if any members can confirm.

2018 IS350's horsepower got bumped up to 311 IIRC, just like the refreshed GS350 did a year ago.

That's because your car is AWD.
