Hi. New to Skoda. Just bought 2018 Octavia. Just SE technology. Great car and 1.0 tsi engine. 
Thinking of fitting wheels and tyres from mark 3 VRS via e bay to pimp it up a bit. 
Will they be a straight fit?? I guess ride will suffer a bit. Any other things to consider. 
Many thanks for any help and advice. 
Steve. 

They will bolt straight on with no issues at all.

 

I went from 16" to 18" on my Superb and noticed little difference.

 

I would advise having the 4 wheel alignment checked over as they are quite sensitive.
