Wira SE seats are not semi-bucket or anything. Just sporty looking seats. With that kinda budget though, you're looking at the Recaro NJoy at best and personally if you're looking for body hugging, you probably can forget about it.
This fella selling 300++ and it looks like it's a Wira/Satria so should be PNP for your Wira. But it's not great for support. Better than the Wira SE seats but not great.
If you can bump up the budget I'd look at these :
But you'd need to modify the base or you can opt to buy these :
But personally this is my choice purely because of my size and how freaking comfortable this is :
On the topic of comfortable - I'd avoid fake seats. Generally they are just extra padded normal seats and generally they are uncomfortable. I'd rather you buy SSCUS seats. They are within your budget (new!) and are better than fakes in terms of comfort and support. They aren't on the same level as Bride, Recaro, Sparco, etc but they are great budget entry level seats.
This guy rewrapped his seats to Recaro cloth - very good. Better than the stock PU type seat.
This guy sells the slider and base plus install with the seat for 1400. But you can probably buy the base and slider used for about RM350 to RM450 and then one used SSCUS seat for RM380 to 500. Well within your budget.
I actually have SSCUS seats for sale but my friends have booked them for the moment otherwise I'd offer them to you.
