    I am having some bad rubbing on both sides when at full lock and going up a slight incline.

    Surely something is wrong - the ride height is stock?

    Anyone know what could be causing this?

    you might verify the ride height is stock. Previous owner may have put it at different height (i.e. CS height vs Modena). Also, what tires/wheels are you running?

    Stock wheels or aftermarket?

    Wider tires than original?

    Changed suspension to aftermarket?

    Lowered ride height?

    Badly worn ball joints and bushings?

    Might need to roll your fenders ... depending on where it's rubbing.

    Tyres are 215/45/18 P-Zero, and the arch height measured from the floor thru the centre of the wheel is 66.5cm.

    I had the same problem when I got my 360. It turned out the ride height was a little under the low point for factory spec. I had the dealership raise the ride height to the top of factory spec, which helped a lot. As I recall it was less than half an inch, but it made a big difference. I then had the dealership's recommended body shop roll the fenders. The body shop did a beautiful job, and between the height adjustment and the fender adjustment, it fixed the problem. But the dealership mechanic said it was not uncommon for the tires to rub when you have the wheels at full lock and are going up an incline (which isn't unusual: that's what I often experienced when turning into a driveway off the crown of one of our local roads). I'm glad to have it fixed but it was a pain to get fixed.

    I had read in various threads here that rolling the fenders should be cheap and easy. Perhaps because they needed to repair the damage I had done before these items were corrected, the project was neither cheap nor easy. But ultimately I was happy to have it done -- several body shops refused to even look at it, concerned that rolling the aluminum might weaken or damage the fender.

    Good luck. I hope you can resolve this easily. I would suggest starting with having a good mechanic check the ride height.

    I hear that a lot of people uses this with success:
    https://www.jegs.com/i/Eastwood/352/31158/10002/-1?catargetid=230006180000851894&CAPCID=174782688879&cadevice=c&catci=dsa-65422197566&agid=14687341031&gclid=EAIaIQobChMIno-mqNqB2wIVE6rsCh0aHAtSEAAYAyAAEgKC5_D_BwE

    You can probably find some Chinese-made ones that's comparable in quality at a cheaper price on FleaBay. Come to think of it, the Eastwood one is probably made in China anyway.

    Thanks for the replies, have contacted some arch rolling firms and will see how that helps

    Strange this is happening though as I have seen a lot of cars way lower than mine!

    I don’t understand where your tires are making contact. If at around the 12 o’clock part of the arch, yes, rolling the fenders is a good idea. Even with stock wheels and tires, they can make contact at that point when the car is driven hard and the suspension compresses. If you look at a lot of 360s, you often find bending or other evidence of contact at the 12 o’clock position on the fenderwell arch.

    As for cars lower than yours, I can’t really say without looking at what was done to them, but it’s not unusual for people who do extreme lowering 1) to not drive their cars hard enough to cause a problem with contact; in other words they do it for looks and use the car mainly for cruising; or 2) they have made other mods to account for the reduced clearance; or 3) the tires make contact and they won’t admit it or care. The front suspension geometry is such that at extreme compression, the tires come very close to the inner front fender lip.

    to the OP, Nothing is wrong with you car, all 360s do that,

    do not go full lock unless on level ground, go up steep angles at a 45 degree,

    the cars fronts are buried up inside the wheel wells by design,

    rolling the fenders needs heat and an experienced shop ideally.
