Rear shocks mounting
panichat - 31/8/07 at 08:35 PM

Hi
I'm using an escort axle.
The shocks are a bit long to sit comfortably on top of the trailing arm blocks, but could be angled back to sit behind and about 2cm lower (and off to the side). Does it matter if they are angled backwards as long as they are vertical lengthways?
Thanks

You'd be best to angle them in towards the centre like Jon Ison did.

I've had a look at the pictures of Jon Ison,s car in the archive but couldn't fin any that shw the rear shocks arrangement clearly.
Do you mean having the shock bolts north-south ad having the shocks leanng in like this / ? That could be doable if I can find space for the access to the bolts for the upper mounting.

Cheers

No.

Tops nearer together towards the centre of the car.

No.


But is there a valid reason why not to space them out at the top in anyones HOP

If the shocks are mounted like / then you would get a falling rate in single wheel bump or roll. If this doesn't make sense, then imagine mounting them at a silly steep angle, the shock would be horizontal at full bump giving zero spring rate.

Mounted at 90 degree to the axle you get a very slight falling rate in single wheel bump/roll. Mounting them with the tops slightly inwards (i.e. aim for 90 degrees between shock and axel at full bump) will tend to counteract this.

It makes sense. But surely if the top mounts were outboard of the bottom, by say a maximum of 15 to 20 mm, then even at full bump at one side and droop on the other on a live axle with panhard rod then it's not going to make a huge differrence is it??
