I've silentcoated my tailgate which made it a bit heavier but just about perfectly balanced, but this morning I've fixed mounts so that I can bunjee my grip strips and levelling ramps to it and that has tipped the balance and it now droops about 20º. The current struts say 900N on them, so what are my options? Do I have to go to full Cali strength ones or is there a spec inbetween? Will T5 struts fit, or are the T6 ones different? I've got no plans to put a bike rack on.
