avon rear suspension setup again(any comment appreciated)
Evrim - 13/8/10 at 04:01 PM

Hi Mate’s
After a long break I am now in a position to make some progress.
I know this topic was discussed before but most of the people that are experienced with this problem use the readily fabricated chassis and suspension components but I fabricate all the things myself and I haven’t fixed the suspension brackets yet so according to yours comment I can make some modifications easily.

when I’ve just assembled the rear right hand side components As mentioned in the book I set the gap between front of the lower wishbone to the chassis at 100 mm. But as seen in the picture below there is no way to line up the upper wishbone with upright even though the ball joints positioned as backward as possible





According to this problem by using the book dimensions i made some calculation and I was shocked. The suspension setup is completely wrong .I put wishbones on the table and simulate setup on the same layer to see the error as in the picture

To solve this problem I spun the bottom wishbone through 180 degree. But in this configuration the gap between front of the lower wishbone to the chassis becomes 110 mm. Does this make any problem? I will make my own GRP

You need to upload the images as jpg or gif to the site (into you photo archive) before adding the linky.. I bet you can see them but we cant!

are you sure you have the wishbones upper and lower and the rear hub carriers the right way round as they are all right/left handed.The mistake is easy to make as the differences are very slight


Evrim - 13/8/10 at 04:29 PM

I am trying to upload the pictures


Evrim - 13/8/10 at 04:31 PM

can you see mates


fazerruss - 13/8/10 at 04:34 PM

have you made the rear hub carriers yet? It should become clear when you do, the centre line mounting point of where the bones bolt to the carrier is meant to be offset to match the bracket on the rear carrier wich is also offset.once its all bolted together the carrier will sit true plumb


Evrim - 13/8/10 at 04:40 PM

yes i make
can you see posted photos fazerruss.you can see them in my photo archive

looking at your picture it seems to be correct but cant be 100% sure. Dont assume all mesurements in the book are correct cos there are quite a few mistakes . I ended up driving down to tiger in peterborough to take my own measurements from one of their chassis cos there are differences from the book dimensions at the front end. Ill double check to see if there were any mistakes on the rear mounting points.

where abouts are you? if local you are welcome to come bring a tape measure take a look at my chassis or maybe there will be some one else close to you

thanks fazerruss
but i am from CYPRUS


Evrim - 13/8/10 at 05:08 PM

i am not sure but i thing i am the only man who build kit car in cyprus


Evrim - 13/8/10 at 05:14 PM

what was the result of mesurements ?did you find any mistakes on the rear mounting points.Can i trust the book


t.j. - 13/8/10 at 05:19 PM

In the end I decided to make my own.....

If you don't use the body, your free to choose.

That 110 mm rings a bell, there is some info here... let's use search..

And there are a lot of faults in that book.

I think there is another Avon builder in Cyprus or may be Greece ( sorry I know there is a huge difference!) his avatar was a picture of a childs toolbench,somebody may be along soon who remembers him.
The dimensions at the rear seem to be correct but I took some extra measurements of the diagonals so to check my chassis was true and that the bodywork would fit. If you message me your email address I could scan them and email you them from work next week. I dont have a scanner at home. They are a bit rough and covered in welding spot burns but will prove very usefull.

instead of 100mm the 110 mm gap can make effect on the position of the wheel in the wheel arch. but i am pllanig to make my GRP myself so I can arrange the GRP to the present position of the wheel.Are there another effect that i cannot consider?


Evrim - 13/8/10 at 05:53 PM

thank's westf27


Evrim - 13/8/10 at 05:57 PM

thanks fazerruss
I thing you have some knowlege about Cyprus.I would be glad to you if you share your data with me.my e-mail is:

Evrim - 13/8/10 at 06:08 PM

The nex step that i am going to do is making the final welding of the chassis.Can someone give me any advice about sequence of welding or anythings else

Make sure that the wheel is in the end parrallel to the centre line of the vehicle
