Spring helpers consist of two notched plates and
two bolts which fit in between the gap in spring,
and give you the ability to raise or lower the car in
whatever height suits you!They come in a pair and
require two sets for the rear and the same for front!
They usually run about $10-15 US per pair! If you
'spread' the spring in rear,travel(squatting) due to
torque is reduced and may remedy the rubbing tire
As far as sites for new alloy rims,do you mean MB
make or aftermarket?I have bought a few sets of
rims from San Fernando Tires and Wheels,inc. and
was an enjoyable experience.
