Looking for review/info for wheel spacers?
 

Looking for some review/info on wheel spacers. Did some search and found not too many company make spacers for rx8 and i don't really want to just put any universal spacer on the car. Also, don't want to replace studs if possible.

i m only looking for about 10~15mm at the back and 5~10mm at the front. My wheels are 18x8.5 offset 45mm with 235/40/18 tires all around, ms springs+shocks

here is what i found:
FEED too expensive for me, +18mm front and +23mm rear, which is too thick for me

H&R again, 20mm all around, too thick for what i want

project kics, i can't find much info on it, other then it's from japan

Mazdatrix, went to their site, only spacer they got is 5mm. unsure if i want to double them up.

That's about all i can find right now. any other ones that would fit what i want?? or is it not possible to have a 15mm spacer without getting longer studs?

thx for any input

so i guess no one has more info other then what i found?
