Triumph V Elan Front Suspension

[vincereynard]

Firstly my first time so hello to all.

Bit of a cheeky question to start.

I'm helping a friend (maybe) install Spitfire front suspension in his Rochdale Olympic and it occurred to me to try and establish the different between Spitfire and Elan geometry.  I had always thought they were much the same but apparently not.

Spit   Track 49"    Top Arm  7.75"   Bottom Arm  10.13"
Elan            47.1                  5.75                          9

SO track 2" less and Bottom arm 1" less either side.  But the top much smaller and at a different initial angle.

Half way down is a diagram of the Elan front suspension layout.  Significantly it is shown in loaded state.  I.E  how it should be with 2 passengers and half a tank of fuel. 

What I'm searching for if an similar image of the SPit.  Dimensions of where the wishbone / chassis pivot points are.  How far apart they are horizontally and vertically?  

From that I could plot the camber changes under roll and bump.  And work out the roll centres.

Thanks in advance.  If it helps I have had loads of Heralds and Vitesses in my past!

There you will find the WSM for various cars, including the spitfire. That has a chassis etc section with the dimensions. Hopefully all the ones you will need.

Many thanks, I should be able to find what I want in there.   Ironically I gave away an identical manual a few years ago.

Starting to feel an irrational desire to have a Herald 13/60 convertible.
