Lowering Car (advice) Whats Legal

[R3TWO]

Gday guys,

I'm looking at lowering my car and need some advice on how low I can go (legally).

This is what i know (feel free to tell me i'm wrong if so!!)

1. Lowest part of car cannot be lower than 100mm from the ground

but i guess i dont know the measurements from the wheel's centre cap to the lip/guard.

Anyone know these meaurements?

Anything else I should know?

Im located in SA.

Thanks for all the hellp,

Much appreicated!

All the time these forums have been around, how come no-one ever bothered to ask these questions?

SEARCH - for threads involving SydneyKid, I'm sure the answers are in there somewhere.

One conclusion you should reach from the information in all those threads - what is legal and what is sensible aren't necessarily the same.

The centre of wheel to guard measurement is the one universally accepted in the suspension industry. It also appears on the recognition documents for new cars. But it isn't the only rule. There are couple of others that can override that;

Ground clearance, what is a legal 100 mm with a 2.5" exhaust will be highly illegal at 62 mm with a 4" exhaust

Headlight height, unless stated on the recognition documents 600 mm from the ground to the centre of the headlights

Suspension travel, 2/3 of the original suspension travel (to the bump stops) must be maintained.

As you can see it is impossible to give a legal centre of wheel to guard height. Although my recommendations would be not to go below 350mm front and 340 mm rear as it compromised the geometry and leaves insufficient travel to absorb the prolific bumps we encounter every day.
