We have, I think, 13 speed bumps over a 1/2 mile down to our house & as I am thinking of a AMV8V (2006-2007) early next year. What are the chances of getting over them? Currently I have no problems getting a mk1 TT & a M100 Elan over them (& a MK1 focus estate but we'll forget that, although it is a good car)

Thanks

Unless they are very aggressive it shouldn't be a problem. Just take them slowly and the large ones at an angle

What speed limit is it???...this will determine the height of the bumps.

I note you are from Essex, Stuart, so the bumps will probably be made from a soft silicone / botox mix anyway smile

Never had an issue in either of mine and they've been over some monsters! wink

the short wheelbase and the very short overhangs mean it should be no problem providing you take it slowly

I have speed bumps near where i live... Some are in the 30mph zone and some in a 5mph zone! I can get over all of them perfectly in my V8V but i do take it slowly!

The ones in North London are a big problem in a V12V.

I've already had suspension work done under warranty and I don't take them aggressively. Even so, some are so steep and large that I hit them even at single digit speeds.

Thought it was going to be a problem over the speed bumps in the Vantage, but have been pleasantly surprised as to how well they go over them - you should find it not to be an issue.

There is a 20mph hump zone near my home.

I even checked these with a timber template, to represent the front spoiler and ground clearance height. Rather laborious, but I did not want to test first with the car and risk damage.

There is a legal maximum height for humps on a public road, which I think is 10cm.

The asphalt pad type humps, particularly if worn, can be tyre killers.
If drivers straddle this type of hump, inside shoulder tyre wear can occur.
Some motorists, who have to drive over these terrors frequently, have been informed at service, that their tyres are ruined, even though there is plenty of tread remaining.

The only solution - one wheel over the pad.

I'm not going to argue with your personal experience as patently, you know it better than I do ! But I will say that my S had identical front & rear spoilers and similarly firm suspension to the V12V, which I've had very few problems clearing the speed bumps with

Perhaps it depends on the type of hump ? I've seen many more of the 'brick/paved' angled type in London than elsewhere and in any kind of car, they seem more problematic if taken just a tad too fast than the smoother, semi circular type that straddle the entire road or the square 'pillow' type that you often see on each side of the road

Suspension is admittedly a slightly different issue to hitting the front spoiler or grounding out the car. I am sure that use requiring regular passing over speed bumps does no good to the suspension at all, particularly of cars like these, as indeed you could argue about our roads in general (pot holes, ramps/drops for roadworks, etc)

It is the speed bumps on Private land that cause the biggest problems.

Such as Hotel Driveways. I often get scraped going over them, to the extent that my exhaust system gets pushed back a good 3 inches over time.

In my opinion any type approved vehicle should never foul anything in the road or publicly accessible tarmac. If it does then we should be able to claim and force them to lower them !!

Mind you this is the UK, so even if we had such power, nothing would ever get done about it.

It's irony that a lot of cars that foul end up being British Cars :-)

On the vantage the thing that tends to grind first is the aero diffusers in front of the front tyres

It's the brick, paved, angled type, often installed just before or after an incline. It is impossible to negotiate some of them without trouble, even at single figure speeds.

I've got a similar set up where I live - no problem at the correct speed. The Aston rides them better than the Golf smile
