will i be able to adjust the self leveling so it dont, go up to high
Yes, but you'll have to come up with something to shorten the link arm on the sensor. Either bending the original(not that easy as its got plastic ends) or make a new one out of coat hanger wire wrapped around the ball joints. Or similar.
But if your looking for improved damping and ride, and DON'T tow or carry heavy loads bin the SL. It's great for levelling but the damping is poor.
So the ride height can be changed , i didnt know that
sorry for the stupid question but why do you have to wrap wire around the ball joints 
The height of the sensor arm dictates the height of the self levelling suspension ( not the ride height of the car that's set by the springs)
So if the springs are changed to give a different ride height, the self levelling has to be re set to the new height.
This should be done by tech2 but the ecu won't communicate on the ones I've seen. So to get round that the level arm on the sensor needs to be set lower, to the suspension arm it connects to.
You can either bend the original, but if the plastic ball joints brake while bending, you'll need to come up with another solution. It's not ideal, but a coat hanger wire warped around the ball joints •-• in a sort of figure of 8 to in effect, make a new arm.
Something more sturdy would be more suitable though, right enough.
Having said all that, and forgive me, it's been a while, iirc mine seemed to recalibrate it's self fairly well in the end. So maybe try that first, see how you go.
