You might see it with the corner jacked up, if not it's a wheel off job, but it'll be obvious when you do see it. If you're really low the 275/40 might be too wide anyway, but it's worth a look in my opinion to delay the outlay of several hundred ££££ if you can. Are your B14s all the way down?Thanks very much. Probably a daft question but presumably to confirm exactly where they are rubbing I'll need to get a good look inside the wheel arch? It's also rubbing on full lock which would make me think it'll be on the inside. It's sitting very low so will likely need to jack up the front to have a look in the wheel arch.
