I need to know if it is necessary to do any fender modification when installing NR NR2 19" F 20" R. I noticed that NR in the NF3 wheels made front and rear wheels narrow by 1/2 inch and now the use instead of 345 325 rear tire the same happens in the front. Some dealers say it is necesary to mod the fenders and other say that is not necesary but with 255 front tire and 345 rear it may be necesary...
Each car is different but in almost all cases it is not necessary to modify the fenders as long as the car is not lowered.
