I’m not telling what to or not to do or endorsing what to do. You need to do your own research. Only sharing what’s out there. I’ve worked with concept vehicles over the last 4 decades with tire companies like Michelin. They’ve grooved custom treads, custom lettering etc etc. https://dbtires.com/ https://www.jalopyjournal.com/forum/threads/smoothing-tire-sidewalls-removing-lettering.848043/
I wasn't implying any of sort. Just surprised what lengths people will go to in attempts to create illusions. Probably the silliest example I can think of such in past couple of decades is "fake patina", but at least in most cases it's not as questionable in terms of road safety as removing (shaving ?) material from tires. OTOH, I've always said "People do strange things".
@Pantdino4 - interesting! Ever since watching this video I drive mine without the lid on the airbox whenever I get the chance: Always conscious of sucking who-knows-what into the engine though! Do you have links to your air filter? I’m keen to implement some sort of solution as the induction noise is absolutely epic!! Thanks!
