A car with hydraulics over the front and rear wheels is “juiced all around.” Lowriding is technically illegal in California, which prohibits any part of the car frame being below the lowest point of the wheel rim.

Lowering a vehicle by removing leaves from the suspension is considered desirable by some, but it’s also considered illegal if lowered by more than one third of its original height.

However, lowering your vehicle without proper authorisation may not only be illegal but can also be dangerous. In general terms, the road clearance of a fully laden vehicle must not be less than 100mm at any part of the vehicle except a point connected with the wheels or mudflaps.

NSW RTA To Require Motorists To Seek Approval Before Raising Or Lowering Suspension. Under current NSW law a vehicle’s suspension can be raised or lowered by up to five centimetres without an engineer’s approval, and by up to 15cm with an engineering certificate.

Duncan Gay, the Minister for Roads, Maritime and Freight in NSW, has recently announced via Facebook, that the laws surrounding vehicle suspension lifts have changed. Now, you can lift your 4X4 a total of 75mm: 50mm through the suspension, and 25mm through the tyres. …

The new 75mm lift rules will allow a vehicle to be fitted with a 50mm suspension lift kit and tyres that are 50mm larger in diameter than the standard items (only half the increase in the tyre’s diameter affects the height of the vehicle).

Paid installation Installing a set of lowering springs or coilovers involves dismantling the suspension either entirely or at least partially. Generally, a good shop can install springs on either end of the car for about £65 to £130, so replacing all four corners of the suspension will run anywhere from £130 to £260.
