Will this set of BBS RS fit my car ?

After a bit of advice 
I have got a 82 gti 
Im after either a set of RM's or RS
I have found a set but not sure how they will fit on the car, has anyone ever ran this set up or is it too wide?
Rs047
15x8 and 8.5
Radinox lips 2" and 2.5"
Will they fit or be too wide ?
Or if anyone has some for sale let me know

Do you know what offset they are? i have a feeling the 8.5's will be too wide for the car. but the great thing about splits is you can mix and match the dishes!

if they are 047's then you should be fine as they were 7" to start with and a good offset

there you go just perfect
