I've been searching for a pic of IS-F front bumper, bottom view. I'm trying to figure out whether the bumper tabs go under or over the under panel. Please help. Thanks.

 

The tabs go under the panel so they are not visible.

 

As Reaper21 said - they go under the panel, where they can of course. Pics as requested

 

Perfect! Thank you so much~ BieberNutz!

 

Welcome! Glad I could help

 

Can you help me by providing the part number for that very same panel? Mine ripped off a few months ago while I was on I-95. The car is lowered on swift springs and unfortunately made contact with the pavement. I'm gonna end up having to buy a new bumper as well as all the tabs ripped off the bumper too. Thanks in advance!

 

@SoulFreak - sorry to hear about that. It looks like that panel comes as a single piece (51441D or 5141053080 @ Sewell). Hope that helps!

 

51441D is the engine undercover. There is another cover in front of that. Depends which one you need.

The undercover isn't cheap, AMHIK.

Just did a quick check - the '08 and '09 use the expensive one. They changed it for MY '10, and it's a lot cheaper. Not sure what is different though.

 

Thanks for the replies and input guys. My model year is a 2011. Hopefully it ends up being cheaper than the older MY's. I'm gonna weigh a few options before making the purchase. I want to keep my car prestine as possible.

 

Plan to buy a bag of the green plastic inserts for the screws holding the cover too. They are too easily damaged, and even Lexus techs strip them out (there were two completely useless ones on my undercover, and only Lexus had this cover off previously for the coolant pump replacement). They are part 90189-06066. I bought a bag of 10 of them and I've been through 4 already - two from Lexus and two of my own. They're very easy to overtighten and strip.

 

Thank you lobuxracer, duely noted.
