Between the 4x114.3 wheels in 15 and 16 inch flow formed wheel like Advanti Storm S1 and Raxer RP10x?

Yet to decide which size to go to as stock is at 16 inch.

If i were to choose either, here the tire size that I plan to run with
For 15 i plan to run 195/55/R15
For 16 I plan to 195/50/R16 which is what I am running now moving up from stock 185/55 (not planning to run 205/50 which is equal ratio to stock as it will make my car slower)

Which one would fit better iriz since without causing fender rub as they have different offset between 15/16 (eg S1 and RP10x in 15 is+35  while for 16 S1 came in+38 or +40 I not sure and +42 for 16 inch RP10X). Would love something in bronze but the market seems to prefer darker colour which I dont really like.

Other suggestion are welcome too, otherwise worse case I just get stock proton 15 inch wheel.

Stock wheel is 6.5jj which came in 185/55R16 but i upsize to 195/50R16 as performance tires only come in this size

Both of raxer and advanti jj value was like 7.0

If raxer 15 inch wheel come with 7.5 jj
Hmm i think both advanti and raxer should fit without much drama?

I actually looked onto putting spacer on my stock wheel to push outward but somehow there more than just about centre bore.

Asked h&r about one spacer which i think may fit my car but was told that spacer was specifically made for honda car as he pointed out some subtile difference in it

noob question, do you mean this bolt as per circled may be too short if I were to fit a 7.0JJ/7.5JJ wheels?

No lah, its just a simple mod to push the stock wheel slightly outer since it was quite inside.
The stock 16inch wheel design was not bad looking to be honest for me, just that the offset is a little too inside for my taste hence if I am considering the spacer option plus my understanding making the wheels outward would help abit on handling side too?
Manatau wanna buy spacer (just a simple slip on 5mm spacer) actually more things to consider other than just knowing what is the center bore diameter.
Also, I not sure if there any decent spacer maker locally who can build one that can withstand my rempit (since many article suggested that spacer will actually bad for suspension), that why I am looking at H&R spacer option but they seems like not making one specifically for proton cars
Plus weight wise i assumed it would be quite heavy.
Kinda suck that 3rd party wheels only come in either matt black or gun metal unless I go for custom wheel route which I am not prepare to spend it.

Hmm, can consider but the minimum spacer length is 5mm, does anyone can do lesser than that?
