Thread: Engineering cert for 50mm body lift vic?

My understanding is as long as your not 0ver 75mm from original ride height no engineer report is required but as you are going 2"body lift I would assume you already have a suspension lift which would then put you over the 75mm.

Check vicroads website for the modifying vehicle guidelines. check in section 13 is the suspension lift information.

Dont forget that you also have to take into account bigger tyres & not just body / suspension lift in your 75mm

Taken from the Vic Roads website,

13.2 VSB 14 Modification Code LS
The following modifications may be performed without certification provided they are carried out in accordance with Subsection 2 General Requirements and Subsection 4 Basic Modification without Certification of Section LS:
tyre and rim substitution carried out within the
limits specified
lowering and raising suspensions (by not more than one third of the original suspension travel in either direction provided the vehicle ride height is not increased or decreased by more than 50mm from the manufacturer’s specification)
shock absorber substitution
spring and sway bar substitution
track rod and strut brace installation
steering wheel substitution (See Section 13.4 below) power steering (manufacturer’s option) conversion
For vehicles fitted with Electronic Stability Control (ESC) also see section 13.7.
13.3 Raising of Four Wheel Drive Vehicles - Alternative to VSB 14 Modification Code LS
In the case of raising the height of an off road type 4WD of ADR Category NA, NB1, MC or MD, and only in this case, the following two options apply as alternatives to meeting the requirements of Section LS of VSB 14. These alternatives are mutually exclusive.13.3.1
Option 1
This option allows a combination of suspension lift and the fitting of larger diameter tyres that results in a total lift of up to 75 mm without the need for the testing and certification normally required by VSB 14 for lifts above 50 mm provided the following requirements are met.
The vehicle’s suspension may be raised by up to 50mm, provided that at least two thirds of the original suspension travel in either direction is retained.
Only commercially available suspension kits may be used. Such kits must be:
Manufactured and supplied by a Corporation;
Specifically designed and tested by the suspension lift kit manufacturer for the make/model/variant of the vehicle being modified to ensure no adverse effect on the modified vehicle’s propensity for rollover, handling characteristics, braking performance and structural integrity when assessed at the combined suspension lift (up to 50mm) and tyre radius increase (up to 25mm), i.e. a total increase in ride height of up to 75mm; and
Fitted in accordance with the kit manufacturer’s instructions, abiding by any conditions or limitations advised by the suspension kit manufacturer and include a written statement (to be retained by the vehicle owner) of the suitability of the suspension lift kit for
the make/model/variant of the vehicle being modified whether or not installed in combination with the permissible tyre diameter increase.
As per VSB14 Section LS, tyres up to 50mm larger in diameter than that specified by the vehicle manufacturer may be fitted provided:
The entire tyre cross section is covered by the vehicles bodywork in plan view with the front wheels in the straight ahead position; and
The tyres do not foul the bodywork or any suspension or steering component under any combination of suspension and steering movement.
13.3.2
Option 2
This option preserves the requirements of earlier versions of VSI 8 as an alternative to meeting VSB 14 or Option 1 above.
A vehicle may be raised by modifying its suspension provided the available suspension travel in either direction is not altered by more than 1/3 of that specified by the manufacturer. In addition, the original relationship between the front and rear suspension heights must not be unduly affected. Brake line length must be adequate for the range of suspension movement at the revised ride height. The vehicle must not be raised by the use of extended or adjustable shackle plates.
Replacement wheels and tyres may be fitted provided that they comply with the following requirements:
The width of any replacement rim must not be:
1 more than 25mm greater than the widest wheel
specified by the vehicle manufacturer for that model or vehicle series; or
2 less than the width of the narrowest rim specified by the vehicle manufacturer for that model or vehicle series
rims, which have been widened, must have no more than one peripheral weld. All welding must be carried out in accordance with recognized engineering standards, and the rims must comply in all respects with specifications contained in the Tyre and Rim Standards Manual published by the Tyre and Rim Association of Australia
the overall diameter of any replacement rim and tyre must not be:
1 more than 15mm greater than largest diameter tyre specified by the vehicle manufacturer for that model or vehicle series; or
2 more than 15mm less than the smallest diameter tyre specified by the vehicle manufacturer for that model or vehicle series
rim and tyre combinations must be in accordance with the recommendations contained in the Tyre and Rim Standards Manual published by the Tyre and Rim Association of Australia and have a load and speed rating equal to or better than that required by the standards
the wheels and tyres must not foul any part of the body, suspension, steering or brake components
at any position of the suspension travel or steering movement, and, when in the straight ahead position, the guard or bodywork of the vehicle must cover the section width of the tyre

That part mentions specifically suspension lift and tire diameter. I've read this before. It does not state anything about body lift. There is a section that talks about what body and chassis modifications are permissible without engineering. But i'm not sure if i'm "modifying" the body and chassis by installing a body lift kit. I've modified the body by fitting flares on the guards but i have not changed the body by lifting it.

Im also a little fuzzy on Vic legalities having just moved here and am finding it hard to find info on modifications permissable. When I was in QLD I downloaded a huge document from Queensland Transport about all this stuff went into full detail about suspension, tyres, body lifts, lighting absolutely everything however trying to find the same information for Victorian laws is quite difficult I have even walked into vic roads and asked about this stuff and they have no idea they sent me away more confused and knowing less than what I went in there for.

W.A. treat the bodylifts in the same way as suspension lifts, and I would expect the other states are much the same.

The bodylift becomes part of the height change calculation as other have mentioned. If you put a 50mm bodylift in, that 50mm is treated the same as a 50mm suspension lift.

In W.A that means legally you cannot put a suspension lift in a vehicle that already has a 50mm bodylift, unless you are prepared to submit the vehicle for the full monty. Swerve test, and engineering report.

You can't have your cake and eat it too!

This makes sense. I'm certain i read somewhere on the Vic roads website that something like a max of 100mm lift was OK. No more than 50mm body lift, no more than 50mm suspension lift as long as it is not more than 1/3 of the original suspension stroke and no more than 25mm lift by fitting larger tires. Why i remember is because if you did all 3 you would be too high. You could only manage a combination of 2 different lifts. But i'm buggered if i can find that document now. This is why i fitted a body lift to my car. Now i'm trying to find that document again and i can't. I though i saved it but obviously i didn't.
