Brera 2.4 Wheel clearance issue
I own a gorgeous 2007 Brera 2.4 JDTM with after-market 20" black alloys. The problem is that one of the wheels (apparently) cracked and I went through 2 new tyres at £300 each. Had the wheel repaired and was Ok for a year but I've recently got a flat again on the same wheel and I suspect that it's cracked again. I don't particularly fancy forking out £300 every time this happens so I've decided to downgrade to some semi-sensible wheels (17"/18"). The problem is that every alloy wheel company I contact gets confused when I say the word "Brera" and struggle to find anything to fit. Apparently it's due to the large Brembo brake callipers on my 2.4.
Does anyone know what clearance (ET) I would need? What about the use of spacers? I have no experience in this area at all so any help would be appreciated.
I was particularly thinking about these wheels with an ET of 35: 8x18 Inch Wolfrace Assassin Black Polished Cap Alloy Wheels, fitted with 2354018 tyres.
