Stock Sierra Suspension

Post by greg »

I just had a question from a Vehicle Engineer (VASS) about my car.

He wanted to know how much more suspension lift my car had over a standard sierra.

Apparently the rules in Victoria are that you can lift the car by no more than one third of the original suspension lift of the car before you need to get the car engineered.

Does anyone know what suspension a lift Stock Sierra had? i.e. perhaps what was the distance from the bump stop to the springs at ride height? (it think that is how it is determined?)...

Thanks.

Here's the sort of thing i'm talking about...

From this site:

http://www.vicroads.vic.gov.au/vrne/vrn ... ment&Area=[Road+safety+hidden+documents]


Quote:
A vehicle may be lowered or raised provided the clearance between a suspension component and it's associated bump stop is not altered by more than 1/3 of that specified by the manufacturer. In addition, the normal relationship between the front and rear suspension heights must not be unduly affected.

I'll measure up for you tonight when I get home.
But I would imagine that my springs are a bit sagged especially at the front.

Thanks dewse...

If it's not too much hassle - perhaps you could jack the car up a tad so that the shackle is verticle-ish (or the springs are at least flat rather than inverted) - that would kind of simulate the springs when they were new i reckon.

Wellt the front ones are close to flat and the rear have a tad bit of arch. they have been reset before so they should be pretty close.

No hassle ;)

Well the front is:

170mm from the top of the spring to the end point of the rubber bump stop.

The rear

230mm from the top of the spring to the metal plate that limits the bump stop.

Also I measured the distance between the end of the bump stop and where it contacts. The front was 90mm and the rear 110mm

Well they have been reset before but they are still the the stoch springs. They were reset over a year ago so I would assume they have sagged.
