The rears are at the top of the shock, so as you said, you'd have to jack it up.
Check this thread if you haven't seen it before to see the rears:

What size & model of tires are you on ?
Do you mean you are 18 clicks from full soft ?
So even at that setting, the ride is not beating you up over the bumps ?
BC told me the Swift spring upgrade is available for the rears only.
The Swift metric coilover springs shown on their website are 60mm ID, the BC springs are 62mm ID. I'm not sure if you could make those fit on the fronts.
I'm planning on getting Meisters once the snow is gone. Spring rates are softer than K-Sport. You can go 6/6 or 6/4. There's a few guys with them here.
One of the BC Racing sites listed that the front rates couldn't be changed on the 10th gen. I asked BC to confirm it & they did. The guy told me they only make 6K in that type of spring .
I'm not on BC Coils but there's a bunch of guys here that are, some on the max low kit
You're stuck with 6K on the fronts. They told me the fronts can't be changed due to the type of spring used.
I don't think you'll find coils with a front rate lower than 6K.
I'm surprised you rub with that setup. With the stock 235/40 tire size, that setup seems to be the Holy Grail with no issues. I wouldn't think a 245/40 would make that much difference. Maybe the Si sits a tad lower than the hatch, given it's more performance oriented.
The car looks awsome overall
What do you think about the Pilot Sports as far as overall feel & road noise ?
Did you ever consider going slightly wider to a 245/40 ?
