The Importance of a Good Earth

SVA Tips

We try to maintain a list of issues which have to be borne in mind, from others' experience of getting W152s through the SVA test. Click here to view.

Ease of maintenance

Dennis Baker suggested that captive nuts on the nose-cone mountings can make life much easier and avoid the need for an assistant.

If you haven't discovered RIVNUTS this RivNut tool is indispensible for the builder. You never need to use a self-tapper again. RivNuts are threaded rivets which give a stronger, more reliable and more professional fastening.

Wiring within wing stanchions

Carl Rasey gave us the tip that the wiring for the front (amd rear) lights can be tidied up by feeding through the interior of the stanchions.

Where GRP panels meet, there is always the danger of them rubbing. A small amount of grease on the mating surfaces is just enough to stop damage and it will clean off to leave the panels like new.

It's about the only way to get through today's DB tests.

Vintage Tyres of Brockenhurst are stockists of Avon CR28 and TurboSpeed (correct fitment for the W152) which are increasingly hard to find these days.

Vintage Tyre Supplies

AVON Tyres Generally - Ronart has been in contact with Avon and confirmed that they no longer produce the CR28. They also do not have any remaining in stock. The tyre Ronart has used recently is the Turbosteel 70 Series 235/70 R15. Index 101V
Section Width 240mm
Overall diameter 711mm (28 inches)
Recommended Rim range - 6.00 - 8.00 inches
This is the tyre used for V12 cars.
The wheel used on the S6 models is 6J
The wheel for the V12 powered cars is 6.5J
The wide rim special wheels are 7J
The high profile aspect of 27 inches gives this tyre a reasonably period appearance.

So there we have the most practical solution, because we can be assured that these tyres look and handle well on the W152. There are of course myriad other makes, styles and sizes; for instance, Dennis Baker uses Pirelli P-Zero tyres on his much-modified suspension, and these handle fabulously, but they do look modern rather than period.
