sva testing nightmare,
 

hey guy's

first time on the forum, actually posting on behalf of a friend who has just taken a beating over an sva test, app 5 full pages of negative comments,

who or were is the best place to look for answers to what has been given or should i pop it up on here for help??

regards jake

I'm sure if you posted up the fail points from the IVA test, we'd all be able to help out with some advice. Without it it's difficult to see what the problems are. :)

i will borrow the paper work and make a note,

i know for sure one was they tyres are under rated for the speed rating

Well that one's a simple fix - the inspector will check the speed rating of the Tyre against what the claimed top speed of the car is - your mate will have put that on his IVA test application.

If it's too low for the claimed top speed, he'll either have to change the tyres, or re-state the top speed. How he goes about that, I don't know, as I didn't have an issue with that.

You can alway take a look at the IVA manual as well, as it will have all the expected standards in it.

Tyres are in section 46.

The main point from the test is that there are too many sharp edges on the car… but his question is “what are you supposed to do about the lock nuts on the track rod ends” as they were deemed a sharp edge. On the failure notice it says: All hard parts contactable with a 100mm sphere, which form an external surface or protrude 5mm or more from the external surface must have a radius of curvature of at least 2.5mm



Additional information:

1. N.s and o.s headlamp bkts 2. N.S and o.s suspension parts, 3. Track rod end lock nuts, 4. Exhaust shields, 5. Bonnet catches, 6. Windshields, 7. Bonnet ends, 8. Exhaust bkts, 9. Mud wings 10. Wing mirrors.

Wheel arches must be ‘turned inwards’ or have a radius of curvature of at least 2.5mm



The tyres section says:



Each tyre must have the adequate speed capability (speed rating) for the maximum design speed of the vehicle



Additional information:

S rated tyres 112mph, declared road speed 125.

thanks guys

Lock nuts on track rods can be covered with heavy duty heat shrink:

or sleeves:

You could also use some electrica cable glands, like some of the builders in the Sportstser section have. I just used the heatshrink ones from CBS and had no issues on IVA day.

Most of the radius stuff can be got round by using rubber edging on the bodywork. It can 'fall off' after the test :-)

You'll probably also need some nut covers for exposed nut and bolt heads.

If you take a look on my build website, you can see what hoops I had to jump through to get my car through IVA:

SVA nut covers - http://www.cbsonline.co.uk/category/..._Covers,b.html used these all over the place on the front suspension.

As for hard edges, I used rubber everywhere - glued down so it's not "temporary" http://www.cbsonline.co.uk/category/Trim,b.html

For the exhaust I made a spacer bar so the wedge they use to measure impact areas avoided sharp stuff. Otherwise, again rubber trim is your friend.

Can he borrow another set of wheels with higher rated tyres? I'm not sure if you can amend the paper work to reduce the top speed of the car.

My SVA issues and fixes are documented here: http://www.msportster.co.uk/sva-day/

EDIT: GOO posted quicker ;)

As above.....

If you look at my pictures in here......(the last 7 in this set)

you'll see some examples of what you can do with some rubber strips and sleeves.

And there are some good articles here that should help....
