We corner-weighted a Montreal to find surprisingly favourable weight distribution figures, dispelling the ‘nose heavy’ myths! From these figures we were able to use our considerable 105 Series setup knowledge to calculate the optimum spring rates in order to achieve neutral handling characteristics, whilst retaining the renowned good ride quality of all our handling kits.
Montreals have chassis legs further apart than normal 105 Alfas to accommodate the V8 engine and, as a result, we have developed a special 30mm front antiroll bar (mounted in the standard position) to ensure the optimum front roll stiffness. During development, we found that the 29mm roll bar which we use on the normal, lighter 105 Series cars (GT, saloon and spider) and which others choose to use on Montreals, was simply inadequate to control the body roll in cornering.
We also found that the standard rubber drop link bushes were unable to cope with increased forces generated due to the extra weight of the Montreal and were liable to tear out of their housings. As a result, we have designed our Montreal roll bar with special fittings to convert to the ball joint drop links that we use on track day 105 GTs; these are far more durable than rubber bushes. The kit is designed to be used with the standard rear roll bar, which results in beautiful steering feel and poise in corners. The result is that we have made the Montreal handle just as well and corner just as fast as our track day 105 GT & spiders!
