Surprised they are narrower (BMW probably being a wider car), the 18mm one will possibly cause all sorts of stability problems. I recall fitting lower rated front springs to my Calvy Mitchel, which resulted in more body roll (than the MGB GT ones previously fitted) and the result was a much nicer handling (less understeer). The guy who fitted huge anti-roll bars to his probably ended up unable to get around bends! Someone once stated “we moved away from solid axles to independent suspension, and then put anti-roll bars on, thus reverting back to solid axles!” That’s an extreme statement, but indicates that there’s a happy medium to aim for.

I am using a BMW rear bar from E60/61. There are several sizes ranging from a 12mm to a 18mm depending on engine size. It is narrower so you need new brackets on the axle But they are cheap, very cheap. According to the roll bar calculator a 12 mm works out the same torsional rating as our 14mm, the 18mm I got from an M5 calculates as being just over twice nearly three times! I also have a 12mm so will see how the two differ. On Mon, 2 Nov 2020, 10:45 Jim Hearne, <j...@quantums.info> wrote: On the saloon only the ARB itself and the rubber bushes are Mk2 Fiesta. There are no mounting brackets like on the Fiesta, the clamps bolt directly to the floor. And the Clamps are top hat shaped clamps with 2 bolts rather than P shaped with 1 bolt on the Fiesta >From memory they came from Mk3 Fiesta but i might be wrong. Jim From: John R Sent: Saturday, October 31, 2020 4:21 PM To: Quantum Owners Group Subject: [Quantum Owners] Saloon rear ARB mounting hardware Hi All Are the saloon rear ARB brackets, P clamps etc. custom QSC or standard Fiesta MK2? I do have a build manual but it does not seem to specify. Currently running what looks like a standard XR2 ARB 14mm diameter but as I will be rebuilding rear suspension soon thinking of upgrading it.
