Surely an XRG with an XRT bodykit is just an XRT?
                
            





 i upgraded a lil tho,i made new exhaust,and put it on the left side(as ae86's have 
 ) 





 and after u chose an other scene(lets say a car wich has nice rims) it will ask wich objects u want to select(and lets say u want rimz 
) so u chose that,and play with sizes
