H&R Spring Question

So I'm rolling with taller tires which has increased my ride height and the EX is screaming for a slight drop to look 'right' again. But, it already rubs slightly up front on the stock suspension with 4 people in the car when hitting a big bump. So I need very firm springs that drop the car but don't allow it to actually go lower under full compression. My question is, can I get H&R springs made for a heavier model (such as the FX35) and have them A. fit and B. Only drop the car slightly while providing enough compression room to not rub any worse?

If the H&R springs made for the EX drop it 1.2/1.3 inches at each end, what kind of spring could I use to get just 1 cm of drop out of it?
 
Yes, I don't need to go lower than the stock ride height. Right now I'm 1.1cm over the stock ride height but already having rubbing because of my taller tires. So I need to find a way to get back down 1-2 cms without increasing the rubbing.
 
You can also roll the fenders and trim the plastic to prevent rubbing.

And lower it more at the same time
 
I wonder if any after market parts company has made a stiffer spring for the G35 but not with the goal of lowering it so much as firming up the suspension to cut down on body roll, etc. That kind of firmer spring would be what I need for a small drop without getting more rubbing, right?
 
So the bump stops would get hit and limit the travel before it compressed far enough to get to the tire rubbing, right?

Do people ever cut the oem springs? Maybe roll the fenders and do a very limited cut back on the factory springs to get it to settle 1cm lower than it is now?

You can cut the springs but it's not the best solution. I'd say roll and trim and do the H&R's (just what that Sir dude said)
 
not a good idea to cut oe springs, and if u do only the front ones can get cut the rears cant by design.
 
If you are rubbing in the front, there's not that much you can do. Not much to roll and you're likely hitting on one of the plastic screws that holds in the fender liner. I'm assuming the EX is similar to the FX. When people are talking about rolling and trimming the plastic, they're referring to the rear. On the front if you look, there's very little to trim. You may be able to push the tabs that hold the screw up some and get a little more clearance. I did that on mine after I rubbed off one of the screws and got a little more clearance.

I've read that BMW guys sometimes use taller bumpstops to prevent bottoming. But the downside is that if you get a bumpstop that's too tall, you'll be bottoming out all the time and the ride will suck.
 
^ good point. A friend of mine used a heat gun to "melt" the wheel liner and reshape it. It wasn't on an fx though
 
On my previous IS350, I had to heat up the front liner and push it out some for clearance. I was running 20"s and those were slightly larger diameter than stock, when the wheels were turned near full lock, the tire touched the liner.

On the FX, I don't know if reshaping the front liner would do too much. It might help, my tires still rub on potholes and I can see some rub lines on the edge of the wheel liner. Don't know if there's any room under the fender to push it up by the edge. I keep meaning to buy a fender pincher and pinch the fender lip, then trim the plastic back some. Not nearly as much as you can do on the rear, but it might help. And a fender pincher is only like $50 to buy.
