What size spacers do i need if i have 360 wheels on my 456 1997?
I looked into this possibility when I first got my car two years ago because I liked the look of the Challenge wheels on the 456. In a nutshell, It's a bad idea. The 456 is already set up to understeer, and the 360 fronts are 1" narrower than the corresponding 456 units, so it makes the push obtrusive, according to more than one guy who tried it. Much better to go with 550 or 575M wheels, which are the right size and offset. There are several choices: 1] Stock 550 18" wheels 2] 550 Barchetta 18" modular wheels 3] Stock 575M 18" wheels 4] 575M 19" modular wheels (Wicked expensive new, hard to find used). Any of those would be an improvement on the look of the stock wheels, but the stock 17's do ride better than any other choices. Of course, there are aftermarket choices, but I prefer OEM Ferrari wheels. Cheers, George
+1, generally. Stock 550 18" wheels are available new for around $11-1,200 shipped, but I found them kind of plain. If you share that opinion but still want to keep the cost down, you can get a used set of NF2s on ebay or a new set of OZ Superleggeras from Tire Rack for around $3,500-$4000.
The width of the 360 rims (and of the 430 as well) is not wide enough in the front and the offset is way off in the rear. The 360 is light in the front, so the rims and the tires are comparatively narrow, while the 456 has the weight of the engine in the front and consequently rims and tires are beefier. You may have premature impending lock-up in the front under hard braking and you would need to use extra thick spacers in the back.
