Got myself a 2016 IS350 and I'm looking into spacers as well. Question is have they shown any signs of wear and tear yet? I keep seeing friends with spacers having to replace them as often as brakes.
Ive had them for a few months now and so far theyve been very smooth all around. The biggest factor would definitely be getting a high quality brand of spacers rather than looking for a cheaper option and running into problems sooner
Yea I have a 2014 IS250 Fsport and used 15mm spacers and had to trim the studs to make the wheel sit flush. I recently removed the old studs and out new OEM ones back on and am thinking to run 20mm since those should allow the wheels to sit flush. I have other guys with the 2017 IS use 15mm and they fit flush so I’m not sure what’s going on lol.
