Best suspension for street use(low dips)

[SeeyaBud86]

I currently have the S-Tune front lip and Fast Intentions exhaust. The mufflers sit low and the front is sitting pretty low compared to the stock. I live in a stupid @$$ neighborhood and they put up speed bumps which are very very high, I barely clear them now. I plan on getting the Stillen S/C so that means changing suspension, clutch, flywheel, etc.

So what is the best suspension to get without going so low. I know the NISMO suspension is only like a 0.4in drop from the sport...Besides that what are the others? (A little bit lower than the NISMO)

Thanks
