I have a 2011 LS460L AWD..... I got a complete OEM Sport lip kit all around. 2 piece for front/3 piece for rear. The problem is, from looking at the Lip, It appears that I have to drill MULTIPLE holes through my bumpers to clip them in. Has anyone ever bought this upgrade and installed it themselves?

I can barely find instructions on installation which it did not come with. I thought it was going to be just clips and 3m tape.

 

Well thanks for the help ..... anyways found out how to do it on my own. And here is the outcome for just the rear 3 piece Lip kit. Dremel Tool works best. Needs a steady hand and some precision
There is gonna be a lot of holes in the bumper.

Fitment was perfect flush and very tight. No need for 3m tape.
Only thing I'm trying to figure out is the tabs that are on the bottom of the spoiler. Is it supposed to clip on anything else. maybe another lip on the spoiler?

 

I wish I knew enough to help. Looks good though! Good luck!

 

How did the front two pieces turn out? Any pics?
