    I installed 360 modular wheels on my testarossa , the car looks great, the tire fills the arch way more and it actually looks lower and the tires wouldn’t touch the inner fenders even at full lock.
    The rears poke out almost 21mms which make it look a little bit more aggressive without passing the wheel well.
    Now the fronts poke out just a tiny 3.65mms less than before, which is very little, but comparing to the rear I am wondering if I might need to install spacers in the front to keep a consistent stance (the car handles great so I don’t think the geometry is affected) so maybe it is more for aesthetics.
    I don’t want to go with 25mms spacers to poke all 4 tires the same, but maybe just a tiny bit (5mms) to keep the front wheels like OEM.
    Now I know spacers are needed to avoid rubbing of the wheel with the suspension strut, this is not the case as the wheel is around 9mms further.

    Here you can see the front and a rear difference, and the rears flush with the wheel well. And a couple of 3/4 pictures from front and from the rear

    Be careful with the spacers, because you can risk the tyre to rub and damage the fender if you go trough a bump very aggressive and fast.

    No if I just go enough to center the wheel to where the original 16 was poking, it is a difference of 3.65mms so I was thinking 5mms as I don’t think there are narrower ones. Also the new tire diameter is only 19.3mms bigger so there’s still a lot of space between the fender and the tire.

    I am not sure if the pros of those 5mms (aesthetically) offsets the cons of spacers (especially in the front)

    Anybody knows the length of the front wheel hub in mms?? Where this little green mark is? The shop that makes spacers need to know this info to see if they can custom make a tiny 5mms spacer.

    If they are only 5mm they can not be hub centric. But of course you can try and test and see if you will like it or not and if there will be any issues or not.

    When you say they cannot be hub centric you mean they should be a flat spacer (no lip) and the wheel would still be centered on the original hub??
    I asked a seller on eBay selling a hub what was the length of the hub and he replied 16mms, I haven’t been able to confirm this number (I haven’t taken out a wheel yet), but if this is the case I’d still have 11mms of hub flange remaining for the wheel to sit on.
    Is my reasoning about this correct?

    Also regarding the pictures, would I have an improvement in geometry to center the front wheel as close to OEM specs as possible even though the rear wheels are poking an extra 21mms than OEM? Or should I go with a longer hub centric spacer (with lip) to compensate the extra poking of the rears?

    Update on my previous post, the information I got from the eBay seller was incorrect, I removed the front wheel and the whole hub flange is at the most 10mms so a 5mms slip on will not work at all. So the only option would be a centered hub spacer of around 11mms like the Hill engineering one, but poking out the front wheel aprox 7mms more than before might affect the steering feel and maybe would rub so I will leave it as it is.
