Thanks for these. I already wrote a small spreadsheet to compare rolling diameters and such!
The problem here is that I had not initially realised that the offset was different between the Fiesta and Focus wheels. That's not in itself such a bad thing; it means that even with 10mm spacers at the back the tyres don't stick out past the bodywork, but does make the panhard rod location (or length) critical, as I discovered. My main issue is at the front, though; the larger offset - naturally, that makes the inner edge closer to the bits and bobs inside the engine compartment - means that the tyre is interfering with the end of the gearbox on full right lock. (The engine and gearbox is wider than the original). I think I'm going to have to get these wheels back on ebay and look for something 15" 6" wide, 38mm offset and accept them sticking out a little on the bodywork. Part of my problem is that I'm trying to get closer to the default wheel size for the Fiat Coupe to keep the gearing and speedo somewhere close - it's a 16/205/50 with a diameter of almost exactly 24 inches. 15/185/55 comes out half an inch smaller - about 4 percent - and also ends up 5mm narrower per side than the 195/55s which are on there at the moment. -- You received this message because you are subscribed to the Google Groups "Quantum Owners Group" group.
