what is the max mm of spacers we can add before adapters? 3mm?
If you mean, what's the max non-bolt-on spacers? I've gone with 5mm on my past IS and and no issues. In this configuration, it allows for ~7.5 turns of the nuts. Without the spacers it's ~11.5 turns.
But with 5mm, I had to add (made my own) concentric rings so the wheel's center bore would fit tightly over it allowing a smooth vibration-free highway drive (See here: https://www.clublexus.com/forums/bui...ml#post8129179)
Is 7.5 turns safe for "Lexus" spec? I know its safe in my own judgement, I've done track days with slicks with only 3 turns (hard to find 18" wheels/slicks fit over 15" Brembos) and it was still fine so I know that is plenty for short term. I don't think people make universal rings they are all hubcentric nowadays so its not a worry for me. I think the NX would look really good with a RSR drop and 10mm spacer all around.
No, 7.5 turns is not Lexus spec. For me, I never had issues in normal city driving with the occasional aggressive driving. Lexus (and Toyota) would likely say it's "not recommended" and state there's a reason why it's engineered (perhaps over-engineered) to take on the loads on 11 turns.
Is it possible if someone can link me the proper wheel spacers that I can get Project kics preferably in 15 front and 20 rear on the lexus nx and where I can buy them? I wanted them because I want to add the wedsport brake caliper covers on the nx. Not sure if it will rub the wheel but I am currently sporting a stock lexus nx f sport with stock f sport 18 inch wheels. If it is okay that I can put the caliper covers on without spacers, that would be great. But i havent seen anyone here to my knowledge have sport those covers without the use of spacers before.
