@syedfaizan1 I think this is the best comment by @nfssaad , summarizing your all concerns. If you want to keep things simple do it this way. 165 width tyre is also company recommended.
One problem with manual steering rack nowadays that they are beyond repair atleast our local mechanics cant fix it for a longer period hardly six months of constant use. Purely for this reason I put anda Charade power rack, its hydraulic, no change from the interior, everything is done in the engine room, like pump, oil reservoir etc. its bolt on fit. I got it installed way back in 2016 and I have no issues.
