Speed Bumps!!!

[Robbontherock]

Gents,

I'm a Vantage wannabe! Hope to buy one in the next year or two, after a house move.

That aside my new house is situated in a nice quiet street (still to be built), however according to the plans it is going to have speed bumps along the street......

So will this destroy any notion of me being able to own a Vantage, do they clear speed bumps??

Do they ground out on the chassis?

Will I have to resort to trig and measurements???

Thanks in advance guys.

Cheers
Andy

it's only really big speed bumps I have issues with. The standard big square ones should be fine.

Even the big London ones can be tackled diagonally, depends on how patient you are, and how often you will drive the Aston. If its a daily driver, and you commute I'd want to know how steep the speed bumps will be.

There's a plastic thing under the front airdam which gets scraped, but they're (relatively) cheap to replace.

Mostly, Yes, they will clear almost anything. Only the most extreme bumps will not be cleared. But you do have to take them slowly, if not, then you will hit almost ALL BIG bumps, it will be the front that will hit, not the back, the back will clear easy ....

Been over many speed bumps in my 06 V8V. Never once had it ground out so I wouldn't expect you to have any problems.

Ya beauty!!

Cheers lads, much appreciate the advice.

It won't be a daily driver, more like a mobile shrine

Game on

My DB9 has been lowered and doesn't scrape and there's some aggressive stuff round here

Trick is to be off the brakes when you reach it... If you're still braking, the front is dipping. A smidge of very gentle throttle doesn't hurt either to lift the front, we're talking mm here. Works for me!

Doesn't your lowering get cancelled out by the bigger wheels?

[Robbontherock]

Thanks again chaps.

Also while I'm at it, how wide is a vantage including the wing mirrors?

Only dimension I have so far is excluding mirrors:-

2005 to 2011 V8 Width: 73.5 in (1,867 mm);
2011-Present V12: 73.4 in (1,864 mm).

My new garage doors are 2225 wide, hence my concern!

Speed humps and cushions on public (ie. maintained at public expense) roads, have limits regarding their dimensions (in theory).

These limits refer to the height, and angle of the initial slope.

If the housing development you refer to will have private or unadopted roads, then it is a free for all. I have certainly seen some very severe humps on business park private roads.

With correctly constructed public ones though, Aston Martins seem to cope.

I am sure that you know of the tarmac cushion hazard. If you straddle those, it can shred the inner shoulder of tyres when the tarmac is worn. I creep over in first gear, with only the nearside or offside wheels going over the cushion, then full revs (if engine already hot) along to the next hump.

Man takes centuries to progress from cart tracks to smooth roads, then makes the roads artificially bumpy again.

From astonmartin.com:

Width excluding mirrors: 1865 mm (73.4")
Width including mirrors: 2025 mm (79.7")

So you will need either a) a very good aim or b) (more realistically) powerfold mirrors.

I have to fold my mirrors in and out every time I put it in the garage.

[Robbontherock]

Thanks for that, looks like power fold mirrors is on the list

No, they're the same as (or very close to) the original rolling radius. Increase the wheel size, decrease the tyre profile

Otherwise speedo wouldn't work and gearing would be all to cock.

Ah fair enough. I thought that you changed from 275/40 R19 to 295/35 R20. Does that equate to the half inch increase to wheel centre line? I thought it was only a 5mm decrease in tyre profile?

tyre profile is a % though. Haven't run the numbers, but 40 - 35 isn't as simple as 5mm.

I know that, but if you work it out it equates to roughly 5mm.

[KarlFranz]

Based on those numbers, his car would be 0.23 inches higher with the new DBS wheels and tires.

Oh wait, ignore me. I worked them out wrong! Its actually 12mm, which would take up the half inch extra wheel size to wheel centreline.

I've 13 speed bumps down to my house & 2 are quite large. No problems so far. Just take it easy
