The Lotus Grand Tourers

Does anyone know what the torque setting is for the wheel nuts on a 1986 model SE with 15 inch Speedlines? Looked through my workshop manual and it's not listed. I guess it's the sort of thing they may have put in the Owners Manual, but I haven't got one of those.

I have an 87 with speedlines - the handbook says 65lb ft but I always torque them to 70. not had any problems.

Mark.

Thanks Mark, much appreciated
