Rear wings and the IVA

[dic price]

I believe that the rear wings originally supplied with my Sportster kit will not pass the IVA when fitted, and that either a new style wing will have to be purchased or the original wings modified. Is there anyone who has achieved this mod? If so could you possibly share you experience?.

Building Kitcars either induce or are the result of insanity. From the shallows of my wisdom the tail lights need to be vertical - one way of dealing with this is to pack it out at the top. The 'Car Builder' catalogue shows how.

Why not fit some Morgan rear lamp pedestals and lamps, the plastic pedestals (£7.00ish each) from Brands Hatch Morgan, and the Land Rover rear light type from anywhere that stocks this E marked type lamp. This Morgan type set up has approval almost globally , so what have you got to lose.

Re: Rear wings and the IVA

The angle of the rear lamps is not the issue I have already fitted angled pedestals and land rover lights. The issue is the coverage of the rear wings, apparently they do not comply with the latest IVA spec in the way that the rear of the wings do not cover sufficient of the wheel and have to be lengthened. Marlin are already suppling this new type of wing on the kits that are being sold now but I was enquiring as to whether anyone had altered the old wings to comply.

Jason (The great old one) who doesn't seem to be very active here details how he got through IVA with the old style rear wings. He fitted some extensions You can view his IVA section of his build here http://www.greatoldone.co.uk/galleries/iva/

The Cabrio has a very similar rear wing and has the same IVA problem.
All of the Sportster/Cabrio builders who have put our cars through IVA have made some kind of stiff lower mudflap ( a soft flexible one may fail).

In my case I bent some thin aluminium and "glued" it to the underside of the wing using some silicon sealer - just strong enough not to fall off during the IVA test!
Don't forget the radius rule again - you don't want to cut someone's shins as you run over them whilst reversing!




Ian Morris did the same on his Sportster: although he used nut and bolts to secure his.

Nigel Beats also did much the same:

Remarkably, my extensions fell off shortly after the IVA! - leaving the nice lines originally designed by Marlin, rather than the less pretty lines of new design.

Re: Rear wings and the IVA

For those of us who fondly remember pre IV/SVA days. Police check Mot and away. Read Fresh Ayre in March Kitcar mag. Why do we think that we will be free of bureaucracy after brexit? Our own bureaucrats are more than capable of stifling us as European ones.
Why do we need all the stupid SVA rules? We don't but you cannot reduce bureaucracy. It is self perpetuating. Ayres views on HS2 are scary, suicide truck on the track and a train that takes 5 miles to stop. Read it and get angry, one way or the other.

Re: Rear wings and the IVA

I have to disagree with you slightly Dave. My Spartan Treka had edges that would have made Boudicca’s chariot seem tame, so generally SVA/IVA is a god idea to ensure that vehicles are relatively safe. As for Brexit, well it doesn’t matter much if the bureaucrats are here or in Brussels we the proletariat won’t have any influence.

Re: Rear wings and the IVA

Chris, My point exactly about brexit In Fresh Ayre he makes the point that in Canada groups like car clubs have more influence on their representatives than we do. Re your Treka surely you wouldn't need SVA to make it safe and an MOT would probably have failed it. I do tend to expect common sense , which is in very short supply these days.

Re: Rear wings and the IVA

Thank you all gentlemen for your excellent advice, aim already in the process of glueing carbonfibre material onto 6mm rubber, and when ready will be mounted on the underside of the wing with probably body mastic for ease of 'falling off' radius rule will apply. Thanks again

Re: Rear wings and the IVA

Just for general info I have just purchased Morgan angled torpedo type bases for the rear wings, from a place in Brum, Morgan agent, was going for the stainless but took so long, had the plastic, came with the rubber seal pads, think it will certainly help with visibility.
