Outer Limits 4x4 Board

hey all i have a 92 ln106r hilux and i have done the usual and fitted ifs / ruf and hi steer now my problem is im fairly happy with the front i have played with the spring pack it now has 5 leaves and the load carrying leaf with bubs 1 inch droped front cross member and 5 inch shackles and the rear i have fitted a untouched ifs pack with bubs 6 inch shackle and the shackle hanger move back 3 inches to give me a 40* angle in the front it has a slight arch in the spring pack but i dont really want to drop it much more as i have about 4 1/2 inch of uptravel with a 14 inch shock but the rear sit 4 inches low and havent even started playing with it yet now i hope someone can help me with ideas should i get some different spring for the rear? i dont want to run more than 1 1/2 lift block as i dont like the idea of it and i dont want to run a 200mm shackle as they stand out and i dont like that idea either but i need the rear to come up i thought that ifs rears and a shackle would have some lift to it but it appears to have droped it to standard height
any help would be much apreciated

thanks in advance steven
