Sportmax 962 Flush look possible?

[obarrera]

I want my wheels to look flush but im not sure if it's possible with my wheels, I have sportmaxes, I believe the sizes are:
BACK 17x9, +35 offset 4x114.3.
FRONT 17x8, +35 offset 4x114.3.

I am getting megan racing coilovers, spacers, and rolling the fenders. I read bout spacers and some people don't reccomend them, I wanted to get 20mm or 25mm spacers, probably 25mm for back 20mm for front, now would that be too dangerous?

Please don't bash, that's why im asking before buying.lol

Also, what kind of tires would be best?

I couldn't find much info on this, seems like most people that have the flush look have work wheels or similar on there cars, and I can't afford that right now.
