Not that I have heard or read..... Assuming you do mean a Lexus dealership.... I do not recall ANY car dealership being labeled or promoted as being "mod friendly".... But, I am new to this so maybe some other members have suggestions.
I guess what you mean by mod friendly is that they will honor the factory warranty if you end up breaking it?
I haven't really heard of one. I bet if you were nice and professional to the service advisor, most would go out of their way to help you out.
This would be pretty much dependent on your "people" skill in negotiations. I took my car to Lexus of Stevens Creek for brake work. I bought a 350 brake caliper that was salvaged which started a slow leak. I didn't expect them to fix it for free. They changed me about 155 bucks to fix it. I thought it was ok since they have to dissamble the calipers and replace the seals and clean off all the leaked brake fluid.
At least they were not being total jerks and lecturer me about modding my brakes. They were nice about it by saying that my calipers were painted and warranty only covered original parts.

Lexus of Stevens Creek Service center has always taken care of me. I know plenty of other owners who have heavily modified cars compared to mine and they've never had any issues bringing in their car for service. Just remember to be specific with your advisor in your requests so nothing goes wrong. Things like not having them wash your car, being careful with your rims, not rotating your tires, messing with your suspension, tire pressure, etc.
