Rebound stopper strap for lowdown Giulia

I wonder whether this topic was already discussed or not, but let me ask about the length of the rebound stopper strap for the rear suspension.
My 1750GTV has Eibach lowdown springs. Considering the shorter spring length I think the length of the rebound strap could be shorter ideally, but I am using the normal straps. Does anyone adjust the strap length or use shorter straps for lowdown Giulia?
Thanks in advance, Takeshi

Thanks, mygtveroche for your quick reply!
For my reference, how much did you shortened the strap roughly? If you could give rough image, it would be very helpful for me.

@onboroALFA

there is no right length. For me it was cut and try, cut and try until it fit snuggly without the rattle that mygtveloce mentioned.

Learning, learning..

In most cases, you want the axle drop to stop just short of full shock extension; the shock is not meant to act as the axle stop. Race cars often have raised upper shock mounts to get full travel with short springs.

Hi There onboroALFA,

As a thumb rule and for standard spring & shock-absorber setups, the distance between the straps passing under the rear axle and the lowest part of the axle itself (at the location where the strap passes undereath the axle) should be enough to have a 13mm or 15mm standard ratchet socket nut to sit upright neatly/snuggly between the axle and the rebound strap.

Pay attention to:

Cars with doubled straps (two strap layers sitting on on top of the other if you prefer) ..... the outer strap is longer than the other.... of course the "socket ratchet nut trick" is to be tested within the inner strap... (rather obviously)

I would assume (not wanting to be nailed on this) that on lowered cars the same should apply as with standard suspension cars.

Not sure my explanation is aboslutely clear.

kind regards,

Thomas

Thank you Andrew and Thomas for your kind explanation. I understood the image of the proper strap length in the relation with shock and axle. I am using genuine double layer straps. I would adjust the strap length using 13mm or 15mm socket. (I believe now my car has bigger gap than the socket length. )
