Title: Lowering springs
Post by: miggy on 03 June 2010, 17:07:13
If i fit a set of lowering springs (PI 35-40MM) on the CDX will it mess up the auto headlamp levelling system. :-/

Know about the insurance but it would stuff up the auto levelling system on the headlights then??

I think it would yes, purley because it'll still be adjusting them for CDX height which'll be 35-40mm out  :-/

Yes of course it will.

Not sure how you would readjust on the wishbones but I think you can still compensate on manual adjusters on the back of the headlights.

My Elite I think the beam adjust could be higher, and when I have passengers it goes even lower.

So if the auto adjustment chan be changed then I would do that 1st/

But in all fairness, I dont know if it can be altered, it it can I would know which way to adjust it.

If it can be done, then prespray all koints a few  times days in advance with plusgas

Cannot understand what to do, i believe mike dundee has the same car and i am sure his is lowered?? i may give Vx a call, hope they can shed some light (Not banking on any info from them though)

Will it though? It'll be as if you had a very heavy load on the car, and adjust the headlights accordingly won't it?

before you change the springs, make marks on an appropriate wall of the headlight cut off points. change the springs and see what you got. try manual adustment as someone has mentioned. failing that "manipulation " of the wishbone levers. :)

I dont think it matters. As long as the back and front are dropped the same (40mm) it will be ok.

If the car is lower all round, then whats the effect?

If you put three Bat Fastards with luggage in the rear would the headlights point to the moon?

If the car was lowered squarely across the axles then the hit of the lights should remain the same, surely??

In theory yes. 

In practice, mine with 3 people in gets worse,

Maybe it's not set right to start with, so what do I adjust, the wishbone link or the headlights.

That was my point earlier...
Having said that, my lights are correctly set up, presumably, because I haven't got any MID warnings, but they seem low to me, they don't reach very far in front of the car

As far as i know the light adjusters on the wishbones let each other know what position they are in. So if some heavy chicks get in the back the the head lights lower .I would have thought that by dropping the car by 40 mm all round it would not matter. What if the car has a full load with a roof box ? It drops? same thing. ;D

Same as me.  Hacks me off when an audi or toyayota behind me outshine my own lights

the "constant" ( unless your fitting tractor tyres as well ) is the wishbones. always the same distance from the road.

the variable is the body height.

with just the driver and no load, ideally you want the headlights to hit the road 25 feet in front ( mot tester come in here)

lowering the body , the adjusters asume load/weight and dip the headlights further.

put the bat fasterds in and even further downward adjustment of the beam.

unless im totally wrong? :-?

But you've got front and rear sensors, it's the relative position of the body of the car between the two that determines the angle of the headlights, if you're lowering both sensors, the level of the headlights should be about the same, possibly a little higher...

unless I'm totally wrong  ;D

ok, could you run out of scope/adjustment then? :-?
Title: Re: Lowering springs
Post by: jonnycool on 03 June 2010, 23:56:53
Possibly, maybe someone who's already lowered their car should try to confirm or deny this. Sorry if I've sounded like I know what I'm on about, I don't  ;D
 I'm just saying what I believe the height sensors are designed to do

Thanks for all your input chaps, i have sent a PM to Mike Dundee as i believe he has the same car and lowered, see if he can shed some light on it (Excuse the pun)

I've had my estate lowered since Dec last year and to put it simply no-one has flashed me at night.  Knowing that there are several million drivers out there just itching to flash you for leaving your beam on I think there are no adverse effects...
