Koni with oem sport springs

So currently I have koni str orange struts with hr springs(gray), ride is firm, but has very fast rebound and handles very very good, barely any bodyroll. What I hate is the fact the car has a racked look. Front gap is 0,as in tires are tucked, rear has 1 finger gap. Oem size 225 40 front and 255 35 rear tires. Has anyone mixed springs with sport springs upfront (will most likely raise it) and hr rear. Looking to raise the front and I'm sure the sport springs will do that. I've done the e39 perches, replaced front strut bearings and it helped, but not enough raise to satisfy me. I don't rub either due to camber and m3 arms and such. How will the car ride? I've always owned cars with coilovers so never knew how struts and springs would ride.

We just had a thread on this...

You say you've done the E30 perches already, correct?

If so, you can also add the thicker E30 9mm spring pad as well (have a look at the last few posts in this thread):
http://www.e90post.com/forums/showthread.php?t=1157626

Lift the strut in the clevis however much it takes and in addition to the thicker spring pad, that will get you even front and rear. Or stack/add plates above the strut bearings to give you a bit of a lift instead...or do all three. Difference being that the E30 perches and thicker spring pads will give you more suspension travel, which is always a good thing, so do that first.

I wouldn't swap springs. If you're happy with the way the car drives, don't make this sacrifice just for looks alone. Do the above and you'll likely be much better off.

Mojo, Joseph or what ever your name is! Stop messing with the suspension. Either take it to a shop or at least have knowledge person tackle it, someone like YoungBlood who knows what they are doing. Also, of course it will handle differently than Neon or Civic on coilovers.

Taking it to a shop to do something I can do doesn't make sense. I want a fix, paying someone to fix something and than not fix it would be disappointment to me

Ok, so after all the work you did yourself still not satisfied? Aren't you disappointed too? I mean all this labor on your end is in vain. What is next?
Go back to OEM springs? What if you don't like it again? If is too high? Riding frequency would change as well. They are multiple possibilities of raising the front end and not all have been discusses here. Don't be afraid or proud to go to a shop. Compare to the time, risk and exhaustion the cost might be insignificant

Any good ones you could recommend to him? I know for sure that if I went to the places around in hopes of sensibly raising the front of my car, I'd either get chased off the lot, or have to teach them everything I've learned here on my own

I actually do, some good, some not so much but at least they will know what need to be done. Most of what I have learned is from shop/s. I do a lot of work on my own too. I work on other peoples cars as well. But sometimes my own car goes to shop for someone else to get it done. I don't find it embarrassing. Some times is lack of time, knowledge, tools. For example alignments. I have a digital gauge, stands and all kind of tools. Is it worth it? To me no. On shop account I can have Firestone do it for $60. True car enthusiast world is rather small so I was able to find a Honda guy at Firestone who is willing to align mine according to the numbers I request. Others would like you said chase me off.
