Potential major suspension problem
speedyxjs - 23/3/09 at 06:47 PM

How wide are coilovers? Im not sure if they will clear my top wishbones
The only other suspension setup i can think of is inboard but i have no room for that.

From what I remember of Jaguar top wishbones they are quite small. If you need to run the coilover up through them then I think you are going to have a problem.

Hopefully there is something that will fit

Without measuring, most coilovers for sevens use 1.9" ID springs. The coils are usually around 10mm dia. So you would be looking at somewhere around 70mm ish.

If you can't find some the right size you could make an inboard linkage type system.

I dont have room for that
I think i could fit about 4 - 5" inbetween the wishbone.

any pics?

This is the best one i have. The long shafts wont be in the way as they will be replaced with two shorter ones.

Full lock problem

i recon you could get away with it. i'm not expert on suspension, but if you put the top bracket on the chassis rail, use 1.9" shocks, and positioned the top bracket a little further back (you'd need rose jointed shocks though) it might be ok? i'm sure someone will say its a terrible idea though


blakep82 - 23/3/09 at 08:16 PM

actually, forget that, if you can fit the shock (dependant on length) you could put the bracket on the underside of the chassis rail, so the top wish bone won't be an issue?
the angle of the shock would be a little horizontal, so i don't know if the springs might need to be a lot stiffer, or cause some other problems.

Aaah brilliant. dont know why i didnt think of that
Cheers

what sort of angle would it sit at? i'd say you probably don't want more than 45 degrees angle to it, but i'm sure someone will say what effect this would have on the operation if you have to go further

There would be a LOT of sideways force acting on the bracket. I should think quite a bit of reinforcing would be needed

yes, i had thought about that, perhaps a bracket with a corner cut out the base of it, so it would be welded to both the side and bottom of the rail?

like this but make it a bit prettier

If the damper is over 45 degrees you will have falling rate springs, not a good idea


Ivan - 24/3/09 at 11:24 AM

In Cobras with Jag suspension the springs easily fit through the top A arm, and the spring is quiet a large diameter. It's all about where you mount the shock on the bottom wishbone and how far up and outwards (towards the wheel) you mount the top of the shock.

Have a look at some kit Cobras for ideas.

Whatever you do, think twice about mounting the top below the top wishbone - its real bad for spring rates whilst above and outboard of upper wishbone pivots will give you a rising rate spring (I think)

it'll fit one way or another in there.

Hope the chassis is heavy duty though, that jag stuff weighs a TON
