[lost my mojo]

Hi now at the stage of my build that the SVA test is in the back of my mind and I have a couple of questions.

1) The SVA guide I own states that all mirrors must be e marked and yet anyone I ask about this is clueless and it is just the radius edges and the mirror surface has to be of a certain size. Also having problems finding mirrors that are e marked any how.

2) I am having cycle wings covering the front wheels, do they have to come a certain way forward as ideally I want them as far back as possible.

Any advice on this would be a great help as I would hate to fail the SVA on such minnor things.

Cheers

Andy

The mirrors DO NOT need to be "e" marked. The manual tells the tester to EITHER check for an "e" mark OR to look for "equivalent characteristics". In the case of the latter they look for a 2.5mm radius on all "contactable" edges plus a minimum glass area and (in the case of exterior mirrors) the ability to knock back when struck by a pedestrian.

As far as the cycle wings go, I don't think there's any kind of requirement for position but they will be assessed for edge radius and the amount of wheel that they cover could be important.

Hi Andy,
The leading edge of the cycle wing has to cover the most forward edge of the wheel rim when viewed from above, also no part of the wheel rim, above the horizontal centre line of the rim can project outside the cycle wing. Complicated or what!! HTH

[oastbloke]

The draft copy of the SVA manual goes on about "wheel disks" in this section. Is that the wheel rim? or something else?

Hi

Thanks for your replys that helps a lot as it means I dont have to send the mirrors that I have already bought back just radius the edges. I might even be able to put the cycle wings on soon as the weather warms up a bit.

Regards Andy

Remember about the glass area and the knock-back capability on the mirrors too!

"Wheel discs" are, (I think) VOSA-speak for "wheel trims". Don't ask why!

And talking of mirrors with knock back - are there any other options apart from the one or two (pretty poor) styles that everyone seems to sell (M3/M5 look and some other thing with rubber bellows). Tried all the usual suspects - car builder solutions, demon tweeks, SVC, europa etc., but it's all the same couple of styles. What I'm after is the ferrari/TVR style with the mirror unit on a sticky-up 'pylon' from the door. Yes, I could buy the kosher 'rarri/TVR ones but not cheap The ones on the new Mini, Audi TT and MX5 also look quite good, but again its an arm and a leg even from the scrappies. Any ideas?

[Incorrigible]

TVR ones (some) are the same as Citroen XM ones, they're expensive becasue they're electric and heated, part from Citroen is £90 IIRC

Bung on some rubbish ones for the SVA and get some race mirrors afterwards, that's what everyone I know did

Also re radiused edges you can get a rubber trim that goes round the cycle wings for SVA, oddly this "fell off" on the way home too

[Avocet]

The TVR Griffith and Chimaera used Citroen CX mirrors. I think some Lotus and other sports cars may have used them too - they look very nice. Might be a bit hard to find in a scrapyard nowadays but Valeo used to sell them new long after Citroen stopped making CXs. Also beware of temporary edging - the testers can fail a car these days if they don't think the stuff is "permanent".

Don't the mirrors only have to have a"knock back" feature if the extend further than the rest of the body, with the mojo the mirrors will not be further out than the arches.

Yes, I believe that's correct.
