Check www.Jaos.com they make real nice stuff, I guess if you have the $ to buy a Lexus you won't mind their high price. They are stainless and light compared to steel bars.n Nicest I've seen
i have no idea. the bars (center protector) alone should not interfere with that but you should be able to remove the oil filter thru the engine bay [i have yet to change the oil myself in the RX]. other than that the scuff protector (metal plate under bumper) might make it tricky to get to anything under it.
