Coilovers : different size front/rear

[voucht]

Hi Ozzy,
Thank you for your comment.
Yes, might be an idea, but in that case, I have to check if the angle of the push-rods will not be THE issue. I also have to check if I have enough clearance between the radiator fan and the engine.

you could do a rocking upper arm design, like this

As long as there is sufficient travel in the shorter damper you should be fine.

Tilly, yes, it would be great, thank you for the link, but honestly, I want to keep the modifications as simple as possible, so I think I will go for an extension "box" as on the Robin Hood, as Phil advised (I'll post the design of the extension as soon as it is finished, to have your opinions about it)
According to my 3D simulations, I should be able to use 11'' coilovers front and rear. Which leads to an answer for MarkB : the stroke of a 11'' is 3'', do you think it is enough ? The 13'' have a 4'' stroke, so I'm loosing about 25mm of travel.
Thanks for your comments.

Thanks for your comments.

In an ideal world you want to be setting the shock mounting positions 60/40. Be very careful when remounting the upper brackets as they need to be well braced and all forces directed into a braced chassis.

Thank you Mark. Sorry, but I don't know what you mean by "60/40", sounds like 60% - 40% but about what ? Can you be more specific please ?

I actually will not remounting the upper brackets higher, but they will more out, with a special assembly (a bit like on the Robin Hoods). Though, it still need to be well braced. I reopened a new thread about the design of this assembly :

so your comments as well as all others are are welcome !

Thanks for the help.
