I don't know about now but there used to be plenty of dodgy test centres in the UK. a garage I know just used to phone for a certificate on a car for sale and send the apprentice to collect it, the car never went near a test station. You also have the problem of testers finding imaginary faults to generate work.
It's a bit better in France, MOT every 2 years and the test centres are independent businesses and cannot be linked to garages.

I am not missing the point. Yes, lowering the hight reduces the risks of rolling compared to a coil sprung p38. But as with any high CoG vehicle you drive accordingly. Our team Landies are raised 2" and have a full roofrack which makes them top heavy. All drivers are blue light trained. If they were that dangerous we couldn't get them certified for blue light runs. Even our control vehicle is blue light certified, and that thingis so top heavy it is scary.

If you drive properly you massively reduce the need for sudden movements. For purist reasons, coils are disgusting, but they aren't the health hazard you all make them out to be.

If you are doing 70 mph on one of your blue light runs and you have to swerve because some other dickhead causes you to, you ARE more likely to roll the car on coils than on air. Does not matter if you are Lewis bloody Hamilton or how well you have been trained. Unless you do your blue light runs at 25 mph that is.

And if you swim in the sea you're more likely to be eaten by a shark than swimming in a indoor pool. Quick, ban the sea!


There is risk driving any vehicle at speed. If you're taking avoiding action at 70 round here, you've more chance of a head on or hitting a tree. Should we ban all blue light runs? In fact, lets ban cars while we're at it. An ambulance crash t'other day killing driver and cas. Ambulances are dangerous, ban them all!

I think you are all worried over nothing. If Mr American wants to coil his car, fair enough, have fun with it. Unless you go silly high the risks are minimal. You've got more chance of crashing by using aggressive offroad tyres on tarmac because of the increased brake distance.

I will say again. REMOVING the EAS and fitting coils REMOVES a built in safety feature from the car. It IS more likely to roll over. That is a simple fact of physics. It does not matter how good a juggler you are, it will always be easier to hold a brick in your hand and balance a broom handle on it, than it will be to hold the broom handle in your hand and balance the brick on top of it.
 
you have a very valid point, Wambo, but in fairness, so does a two, three or five inch lift. So do big tyres or removing anti roll bars. how many peeps do that, as well?

Maybe a few, but that is done mostly for a singular purpose, most of those cars will not be used for high speed travel.

Corrected for the sake of accuracy :).
I agree with you in as much as if you want a high speed machine, you don't want it lifted, but the OP says which is best. The answer is, as you stated, leave it as designed, however if he was to fit coils and lower it, then that might be different. Mind yu, it would look stupid :eek:. As stated the CofG is the critical component. Even air springs with a heavily loaded roof rack, would be stoopid if doing high speed manoeuvres. Maybe he wants a drag rangie?

If you have a coiled and lifted car you would be silly to use, and you would avoid a lot of high speed maneuvers. It's the unintentional forced and unavoidable ones that would give you a problem. Mine will stay on air. Providing it is sound to start with it can be maintained for several years for much less than the price of a coil conversion.

Funnily enough, a whole EAS system (sans bags) can be had on the bay from Emmotts for less than a good coil conversion.

I think you slightly overstate the rollover risks in running coiled. If you get a set that runs at offroad or higher modes, then yes, big risks. It is why RR won't let you ride that high over 35MPH. But at standard hight, the risks are marginally increased. Although the interrupted areo will cost you in a smudge of fuel.

Wait, how much are conversion kits over in the UK? Here they can be had for a couple hundred bucks.

A good set can be had for around 300GBP (about 50USD these days).

The collection of EAS tricks goes for about 280GBP on the bay.

The roll over risk is greater that is the point. No need to explain to me how the suspension works i already know.

Roughly the same here in pounds as it is in dollars over there. Something that say costs you $100.00 in the states will cost about £100.00 here. It's not called ripoff Britain for nothing. :D:D
