Custom Boot Strut Help

[sheppy1]

Okie dokie! Heard back from company who were actually very helpful...However, they said they aren't sure what needs to be done to achieve the result of the boot being able to lift itself. He said they wouldn't normally provide more powerful struts to achieve this but he CAN do it and they DO stock the standard Astra struts which they can "uprate" (make more powerful) for only a few quid.

But he said I may need a spring assisted strut...Does anyone know if the above can be achieved by simply uprating the standard strut or do I indeed need a custom spring assisted strut?
