The Rota G-Force is a copy of the Advan RS wheel.
11R's are very similar to Advan RS-D which is basically an RS with Dish.
Every company has similar looking wheels, and it depends what you want to run on your car - i.e. $3k worth of rims (genuine advans), $1.6k worth (work) , or $1k(rota). Its a personal choice.
Personally, I bought second hand Gram Lights 57Fs (forged) as they suited the car and application better, BUT i did consider the Rota G-Force at one stage as there is no way I can justify $3k on rims
