Yeh, you a probably right. Maybe thats why I like it so much. I was dreading a horrible ride that the wife would hate and make riding in the back unbearable for my 15 yr son but we all love using it, even for long journeys.

Not having it for a week is so hard!!!

I know exactly what you mean. I had a Mk1 Focus RS which I modified to bits, and by the end we didn't take it anywhere because it felt like a pestle and mortar for your hips :D I don't know why we do that to our cars to be honest.

I feel out of the loop! What's it in for?

A general reply to this thread. Suspension has to be stiffer on taller cars so they don't fall over. The Merc A class is a case in point because the Mk1 version really did fall over (failing the Swedish Elk test) and they had to stiffen it up.

It follows that low slung cars don't need really hard suspension, especially if they are mid-engined (meaning very little of the weight is at the ends of the car). The best examples of this are Lotus (Elise / Exige / Evora) and any McLaren.

You get a better ride when the weight of the car body is very big in relation to the weight of the unsprung components (mainly the wheels/hubs/brakes). Old Jaguars and Rollers rode really well because the body mass of those cars was so great. You can improve the ride of a car just by fitting a lighter wheel and tyre combo - or lighter carbon ceramic brakes.

Some car manufacturers do not test their vehicles enough on our type of B-roads. Although their cars may ride well generally the suspension gets all caught out by the frequency of the bumps that our rubbishy surfaces contain. If you spend a lot of time on those sort of roads some German cars can make you really tee'd off. (Think Audi A3 and A4 here). Damping for the occasional big pothole is only one part of the solution!

Finally it is not safe to assume that one car with a 19 inch rim will ride worse than one with an 18 inch. Why? It would be true if all cars had the same overall wheel diameter. But modern cars tend to have bigger diameters than before. Look at a current Porsche 911 which has 19 inch wheels as standard. The 996 of 2000 had 18 inch wheels in some variants but it had just the same aspect ratio (the side wall height in relation to width). So you would expect the ride of both to be about the same.

I can't wait to see what my 'Stang is like!

Don't the UK mustangs have an even stiffer suspension set up than the mainland euro models?
