Unless you have worn out shocks, if the ride height is a real concern then best to change the car than changing the ride height(if not done properly it might impact the handling characteristics of the car or worse make it unsafe). I did the same coz the roads I had to travel, even the Allion couldn't make it. If you only need just a couple of mms more then it might be ok to modify the current ride.

Thanks all for your inputs. Im also considering another vehicle. but these days are not suitable to go for a newer one. So let's see how it goes. need to do further R&D on this. 

reasons for not recommending strut spacers are that, I lost the comfort the car earliest had after the spacers were put in and it started making a loud thud sound from the rear whenever I went over the road bump so had to extra slow when going bumps. I put 2 inch spacers which made a noticeable gap between the wheel and wheel wells which, to be me was, ugly AF. During sharp bends/ beds with upward or downward slopes it started making a "kiri kiri" sound from the front suspension. Now I have an Axio but I still won't get it done to it due to those issues. I will happily let it bottom out or would ask the rear passengers to get down if I sense its get the bottom scraped. Gotta live with it until I can afford to drive a crossover/SUV..sigh
