20 in wheels

Hi all. Here's my problem I have 20in.wheels&tires on 1994 olds.98 sd.
the front's OKAY. But the wheels on the back are scrubing againt the fender
is there anything I can use to get aleast 4in. of lift beside the kit that
goes in the springs. PLS help in Millington. Don't know what to do at
this point.

If you don't want to use spring boosters, another option might be an adjustable airbag suspension, but that will cost some money. A trick a lot of racers do when they stuff big tires in a car is to roll the fenders for clearance. This might be an option for you. Check with a bodyshop that does performance work

I'm not sure what rolling the fenders are but
please explain . 98 4life
thanks again.....

It's a modification that can be done fairly simply by a bodyshop, basically involves a slight reshaping of the metal to increase clearance between the fender and the wheel. Don't know if its an option for you but trying a wheel with a different offset my also help
