    Question. My 82 Mondial QV needs the bushes replacing on the rear anti swaybar. I ordered the parts but they seem to fit a much larger diameter bar. Does anyone know if Ferrari changed the diameter during the Mondial production or have I been given the wrong parts? Thanks!

    QV bar diameter should be 13.5 mm

    No Ferrari I know of uses a 20 mm bar in the rear, the Mondi uses a 22 mm bar in the front though. Lot's of 15, 15.5, 16, 17, and 18 mm in the rear. Sounds like an aftermarket bar, unless your in need of such a large bar in the rear, it would be wise to remove it and use the 13.5 mm OE one in order to keep the car balanced. Poly bushings on all 4 corners are a better way to remove body roll without upsetting the suspension balance (95A is about perfect for a street car). Next step would be tire / wheel combination, 255/40-18 and 225/40-18 are about the ideal size for the QV, a dramatic improvement over TRX (I currently run Toyo in this size combination).

    jh355 is spot on: I'll go a little farther and say that almost any newer technology tire is an improvement over the TRX. For just for another opinion, I think at STOCK levels of horsepower in a STREET car, a 17" wheel with 215 or 225 sections in the front depending on taste, and a 245/45-17 in the rear.

    thanks for that, I've got the tyres sorted, gave up on TRX years ago! It seems I've been supplied with the wrong kit so new one on the way. Currently thats the least of my problems with the car, someone changed the antenna a while ago and didn't connect the drain tube. Result is that water has sat in that wonderfully absorbent material under the trunk floor, the whole under floor has rotted out, fortunately none of the frame is damaged so in the process of cutting out the rot. Why did they make the rear of these cars so complex?!! Scary pics will no doubt appear soon!

    I would agree snj5, 17" look the best, and have less room between the wheel and rotor, but I found the 17" tire and wheel selection rather slim (I didn’t want to go the 348 route), and therefore reluctantly choose 18". Now that 18's are on the car, it doesn't look as bad as I through it would; the only thing which I will change is the 1/2" increase in ride height. I personally prefer the wheel and top of the fender opening to be a little closer together. So I don’t mess up the suspension too much, a few more calculations will need to be complete prior to lowering.

    You would be hard pressed to “Spin” or fully use a set of modern 17 or 18” rubber on an older Mondi, but where the 18” really shine is in the corners. You can go in hot, negotiate around at nearly full speed. It’s not as fun as the TRX’s which will kick the back out with a small blip of the throttle, but much safer and faster.

    Sorry to hear about the power antenna, at least it’s only the floor pan which need to be replaced, could have been much worse. You will find as you progress through your project that your opinion of Ferrari engineering / build quality will more closely match reality.
