slipar, if ur car is 1.5M with EFI, fitting 15" wheels should not pose a problem with pick up or FC. instead, it will improve ride and handling. too big in size and ur standard brake set ups wont be efficient as the momentum is higher than brake capabilities.
if 1.5 A, go for 14" sudah lah...
go for 16" for the i feel good mood. 17" for evo wannabes! engine transplant is a must!
btw, i do have a set of original wira 1.6 JRD 14" sport rim for sale. comes complete with tyres - all thick thread.
pm me if interested. price? cheap-cheap RM200 for sport rim set(RM50 per piece). add another RM300 for tyres.
