Hey guys, first post here, just need some help. Forgive the pathetic questions but im not greatly technologically minded.

I am trying for more of a hot rod look for the LS8 and have decided on either stockies or a similar looking rim in black with Bullet Centres and Bullet wheel nuts, with white walled tyres.

Question 1 - Any ideas on the rims, i was hoping to use something bigger than 16in?
Question 2 - What thread is the wheel studs on a Statesman?
Question 3 - Are there tyres out there with a decent whitewall (bigger than 10mm) that arent an antique style wheel, dont want to comprimise safety

Thanks Rob
