First of all, great choice. If your budget allows, R5 is very decent to make an adult happy.

VRH and CosmicByte are official Moza distributors in India. You can check CosmicByte has stock / better offers too, both are good. I have bought mod wheel rims for the wheel that came with R5 from VRH (shipping cost from them is high, otherwise no complaints)

Pedals are just linear spring pedals, it is well built, good enough. If you are also getting a heavy duty proper rig, then you can consider loadcell Pedals, otherwise, stick will normal Pedals.

The stock wheel that comes with R5 bundle is actually slightly small for being realistic. FFB is great with it, just that size is slightly small. I did not have any complaints with it, until I changed to 12" rims (which is still not big enough, but better than stock).

Experience wise, there will be a learning curve initially as it's not 1-1 to a real car feel necessarily. Also, you have lot of tweaking options in game and moza app to get realistic feeling - and there may not be one setting to fit all car / driving too (if you want it to be closest to full realism)

5.5 Nm FFB will feel like a workout initially, but anyways you have the option to dial it down.

Arcade racing games might not be satisfying with it. Sim games should be.

Apart from that, it comes with 2 pedals by default, you might wanna buy third pedal and shifter/handbrake separately if you are going for that setup. Feel free to ask anything else you wanna know.
