I dont have anyway of measuring the thread etc of the studs on my 340, does anyone know the specs of the top of thier head?

Need to order longer ones for my spacers

also are they press fitted or threaded in

They re 12x1.25, if you buy extended subaru impreza ones, drill the hub out to 14mm and refit them. They are pressed in, but you can wind them in with a machined spacer and a nut.
I run impreza ones on mine.

mine are 1.25 like.

I just measured them and they are indeed M12 x 1.25 sorry

so I have bought extended subaru ones, do i just need a 14mm drill bit drill the hubs then bash em in with a hammer and a bit of heat and lock tight?

yep, apart from beating them in with a hammer...

just use a spacer and a nut to get them in

so i effectively pull them through using the nut against the spacer?

yep
