Rear suspension fitting

[Maado]

hello , 
i am new this forum, i bought Octavia 2021 , it come with 18" alloy wheels, it was too much noisy and not Comfortable at all for me , i fitted a second hand 16" alloy wheels ,and i got to much better results than before . 
now wondering if can fit a multi-link rear suspension (like the one on vRS) to my Octavia which come with dependent suspension   (Torsion bar), i know that would cost much , but is it possible ?

I have 18" wheels on mine and it spoils the car. Why can't car manufacturer's understand our roads are crap?

The low profile brigade would argue that the sidewalls on 225/45R18 tyres are far too high. However, 205/60R16 and 205/55R17 are clearly going to give a more comfortable ride.

 

For the ultimate ride, maybe use non-standard 195/65R16 on 6J rims (not the standard 6.5J rims that the 205/60R16 uses). A narrower 6J rim would also slightly improve the comfort of the standard 205/60R16 tyre size.

i would very much doubt changing the suspension setup would be possible. Well at least with a cost which would be sane anyway. If you can find someone to change it (and able to get the parts, do the fabrication etc) I would guess it would be waaay more expensive than just trading in your car for a VRS instead.

Compared to other factors the sidewall height has a relatively small impact on handling. Given the trade-off between sidewall height and ride comfort, if ride comfort is at all important most reviewers conclude that a smaller wheel size, with deeper sidewalls, generally strikes a better balance than shallow sidewalls on a larger wheel.

 

Some people might feel that larger wheels "look better" but there will be a trade-off and it might end up that the ride comfort is spoiled too much for day-to-day use.

 

Regarding changing the torsion beam for multi-link - yes, this would improve the handling a lot (much more IMHV than changing the sidewall height), but it would be enormously expensive even if buying all the bits from a scrapyard. Furthermore it almost certainly is not possible because I believe that the floorpan of a torsion beam car  does not have the correct (and different) fixing points for the multi-link suspension.

i am trying to book appointment with the dealer to find out is it possible technically or not.

I doubt 95% of drivers would notice a difference between torsion bar and independent rear suspension. It's crazy to replace it, torsion bar is great, reliable, cheap to maintain and cheap to build.

Probably not if they are not "enthusiastic" drivers. It does make a big difference though to the car's behaviour as you go faster round corners, particularly on bumpy surfaces.
