Ok Chaps 
  
As part of my ever lasting program of modifaction (of at least buying), wheels are now coming to a head, so I need to clarfify some wheel issues 
  
If I stay 18, then I am looking at 285/40 on the rear and 245/40 on the front, car will be lowered 
  
If I go 19, will be the same 
  
If I had 20's Im guessing this could be an issue and am I right in thinking 20's are really only for aesthetic value anyway. 
  
I how the extra width may effect the turning circle of the car, but will it effect the handling too much, and if I have 19's will this make it even worse. 
  
Will be using the car on the ring (all other required mods will be done) but wheels is a sticking point
