Staggerd tires can I lower 1.5in?

So i have 245/45/17 in the back and 225/45/17 in the front. Will the back rub if I put in lowering springs and new struts?

I recently installed Eibach pro kit springs all around on my '03 325i ZSP and had no issues. It lowered the car, but not 1.5".(Eibach claims 1/4" lower than factory sport suspension) I'm running the same staggard fitment that you are (check your rears, mine are 245/40 zr17), and I bet you could go a full 1.5". I chose Bilstein sports to go with the springs and I like the set-up.. You should get some good feedback on this one- Good luck and have fun with it.

Thank you, I've had 8 months of sobriety and started it off getting into cycling now I kinda feel back in love with my car after I fixed some issues. Get a lot more pride out of something when you do your own work..

The only problem you will have from lowering the vehicle aggressively is if you try for a wide tire on an aggressive wheel offset. OEM offset is very safe so will be good to go!!

Once you go into the ET45 for the rears and slap on some nice squared off tires for the wheel...then you could run into rub issues where you will need to address and modify for extra space. I've run ET45 with 255's in the rear no problem which curve the rubber in just a tad since the wheel is a bit wider and had no issues. When I put on 265's to make the tire look more flat/squared off, that's when I run into minor issues because the rubber is too wide to fit under full shock compression even with rolled fenders and bumper clip delete.

If you do go for the lowering springs, be sure to buy shocks that are matched to them (i.e., valved for the shorter springs) so that they work in concert.

8 mos Roger on your own work satisfaction. Suspension mods reap big returns (along with tires). You will be pleased-
