Chances are if they're stiffer it'll raise the car as well...

PS: if you're looking for street performance you'll probably want progressive springs. Soft initially with increasing spring rate under compression. Linear spring rates are more for precise response but in order to actually get them in a real useful range they'll have to be quite stiff. On my DD(Sorta)/AutoX car I was running 450in/lbs front and 350in/lbs rear, and it rode like crap and wasn't REALLY stiff enough for autocross.

Not really because it'd only be stiffer in order to support a heavier car. Stock I believe is in the 100-110 range on the fronts. And stock usually is progressive.

Most OE springs are progressive. I think you might have just gotten one that wasn't quite as good as they claimed.

Stock I believe is around 110-115 front 80-85 rear.

Yeah I think you'd be hard pressed to find a spring ots that's stiffer and OE height. There are some places around that will wind you springs, I think I've got someone here local that'll do it. I have no idea what it costs but it might be the best route for you in the end.

Probably obvious but don't forget the strut mounts.

Yeah most people cut off the factory spring perch and mount the sleeve lower. Also how did you decide on those springs?

I was just wondering if you somehow looked them up by size and rate, or if you just searched by vehicle

As joey mentioned, you can still purchase custom springs if you are unhappy with the Summit springs. I don't know how much these will cost you, but take a look at RCS (Renton Coil Spring). I've used them for a few of our SAE cars and they worked out extremely well. (This is not a pitch for RCS, but some useful advice based on my/team experiences)
