Better not because 235/45 is about 0.5cm taller sidewall than 225/45 so the back of the car will be even higher by about 0.5cm. My suggestion is stick with original 235/45/18 but try find more affordable option yet still very good, for example the newest Falken FK510, around rm550 as shown below:the difference is huge what do u think if i use 235/45/18 rear and 225/45/18 for front? since it is RWD, so had a feeling to do such configurations. is it normal? any setback with that? how about the swapping the tyre part later on (coz cannot swap front and rear anymore since different sizes)?

Or else you can opt for 225/45/18 front and 245/40/18 rear which is also still cheaper than 235/45/18. 245/40/18 is only about 3mm lesser sidewall height compared to 225/45/18 so less obvious difference than 235/45/18. This is the most common staggered size used by the guys in the club. I myself is also considering to opt for this for my next change. The downside of it are:
- the ride comfort is lesser too
- your fender gap will increase (not an issue for lowered car).
- your handling might be more understeer
- your front tires will finish even faster than normal.
- cannot rotate front/rear.
