Hi everyone
Hope someone can help.
I'm looking into tray backing my r reg disco but having lots of issues getting my head around this iva testing malarkey I assumed it would need one however I found this info on there website stating that vehicles older than 10 years do not require iva test or am I getting the wrong end of the stick.
I want to stay on the right side of the law however £450 for someone to tell me the redundant foot of overhang I will have cut off has made no alteration to the strength of the chassis seems like a monster lay out. Anyone experienced in any of this I would appreciate your input

Thanks
James

I think as a rule it should not need an IVA if you haven't cut the chassis between the axles and it still has the same engine/gearbox.

But best I can find is, "only VOSA can decide if it needs an IVA or not". However I have no idea how you get this answer without actually going for an IVA in the first place.


That all said and done. I struggle to see the point in tray backs. They are hugely UGLY things and really offer nothing other than more work and less practical use than either bobtailing or pick up'ing a Disco.

And it's largely the "tray-back" scene that has caused most of the issues with VOSA/the Police when used on the road.


My advice would be - don't be a sheep and tray back just because you think it's the "hip" thing to do and have seen others doing it.

And if you are doing anything so "extreme" that you really must have no bodywork. Then the front body of a Disco isn't the vehicle to be using anyhow. And you should probably be looking at a non road going vehicle, something more bespoke, in which case should then be inspected.

The rules on IVA are simple - any amendments to the chassis in a build process will trigger an IVA inspection.

There is a myth that this doesn't apply if the wheelbase is unchanged etc but unfortunately trimming the chassis rails at the rear for a trayback is deemed to be a significant change. If you think about it, the fuel tank (when full) is a fair old weight to support and the dangers of a loose or non-structurally supported tank waving around in the breeze could be immense...

So... if you go down the trayback route, it's time for an IVA!

Also, the 10 year bit and the OP's extract shown above relates to Nomal IVA for vehicle builders and manufacturers whereas 'our' sort of thing relates to kit built or amateur built vehicles which require a Basic IVA.

Hope this helps...

Hi thanks for your reply I assumed an iva would be required but like I say there are so many conflicting views and the way things are worded don't outline everything very clearly in my opinion hence asking the question.

Thanks
James

Hi,

I believe that the 10 year rule applies to vehicles being imported.

I also have read that the SVA was introduced at the request of the UK motor manufacturers, to prevent back-door imports by foreign manufacturers. Kit and Rebuilt vehicles were just added on.

There are some concessions for goods vehicles, but I don't know how they would affect you.

Bodywork is not included in the points system ... unless it affects something else eg - seat belts. I have read something recently, via Google, that suggested that cutting the chassis is OK depending on where it was cut.

I know that somebody converted a Citroen 2CV into a trike, and had no problems having it inspected and accepted by his local VRO ... but I know no more than that.

Hi again,

www.the-ace.org.uk says ...

Chassis.

Q) What is classed as chassis? Is it purely the outer longitudinal rails or are the crossmembers between these also a part of the chassis?

A) Chassis should be taken to include crossmembers.

Q) We know that cutting or shortening a chassis is classed as modification but is this relative to the vehicle wheelbase i.e. the chassis must remain uncut between the 2 axles but anything forward of front or aft of rear suspension mounts can be removed?

Doh! It looks like I maybe missed a bit. Sorry!
