I assume when you said "yes i could go more meaty in the rears but front will almost bef hit my strut", that you meant if you when more meaty in the front even with 10mm spacers then you would still rub the springs in the front. If that is a concern, just get even bigger spacers. I know you can fit 15mm without worry, and I believe even 20mm. (move up to 25mm and then you have to start worrying about rolling and/or getting wider fenders)
