    those are really nice rims, exceptional. I have no idea if they will fit, sorry.

    im just going to try a different look and will set aside my VX rims for a while.

    I'm afraid the offset on those wheels is completely wrong. Standard offset on the Mirage is positive 46mm. A negative offset of 6 mm would have the wheel 52mm outwards from where it needs to be.

    I dont know offsets and I'm really bad at maths, but shouldnt +46mm (stock) replaced with -6mm have a difference of moving the wheel/tire 52mm out?

    I would encourage the OP to use the website below:
    https://www.1010tires.com/Tools/Whee...et-Calculator#

    Pushing the wheel out would likely have a "poke" stance. I'm personally not a fan of wheels/tires poking out of the wheel well, but to each his own.

    You are absolutely correct Ares! My finger or my brain must have slipped when I was typing. I've edited my post to the correct math.

    Will there be something like a difference of weight distribution to the tires, shocks etc? will there be any concerns when using a negative offset instead of the normal offset?

    ANY change to the stock specs will affect the car/parts negatively. The engineers who know maths built the rest of the suspension/steering parts with the stock wheel/tire specs in mind.

    Case in point: I've had to replace the ball joint (LCA) sooner than (i believe) most people on here because of the wheels/tires I've been using. But I'd pay that price for both the better look and better performance that I get with my aftermarket wheels and tires.

    A possible concern could be shortened front wheel bearing life. The front wheel bearing on the Mirage consists of two ball bearings sandwiched together into a single outer race. In the standard configuration the offset of the wheels places the centerline of the wheels directly in the middle of the two ball bearings so that each ball bearing is carrying half the load on the front wheel. With the negative 6mm offset wheels it places the centerline of the wheel 52mm outwards from the middle of the two ball bearings. In effect the outermost ball bearing is carrying probably all of the load on the wheel and the inside bearing carrying hardly any or possibly even a negative load (upward instead of downward). Actually, it will place the centerline of the wheel about 34mm outside of the wheel bearing assembly, instead of in the middle of it. I'm certainly not saying it won't work, and it will surely look pretty cool, but this doesn't really bode well for the life of the bearings.
