please help...wheels offset/tires settings

[s14mc]

i have a s14. im running tein flex coilovers.

how does

18x8 +21 with 235 tires in the frontand 18x9 +33 with 255 tires in the rear

sounds?

will they clear my coilovers as well as my stock fenders?

Should I run 18x8 +26 up front instead? to have a better clearance to the front fenders? (if +21 with 235's will rub)

Thanks alot guys
