I've read that people have put a suspension spacer between the spring and perch to lift the spring away from the top of the tire.
The question I have is where can I buy a pair?
Here's a picture of my Brabus with 215/35-17 on the front. I'm considering putting 205/45-17 on the front (b/c 205 is probably the narrowest I should go with 7.5" wide wheels, I can get them in snow and summer run flat tires which you can't get in 215/205s in 35s/40s).
So I need to lift the Spring up off the perch that it rests on by about 10mm to keep the wheels from rubbing.
Believe it or not, the spring with the 215/35-17s are reported not to rub on the Spring. Yet I have no doubt they will with taller sidewalls 205/45-17.
Wheel spacers won't do the trick as I'd have to get wheel spacers that were over an inch thick, so a pair of spring spacers between the spring and perch is what I need.
Maybe perch lifts (spacers...not sure what they are called) are so basic (i.e. like a flat washer) that it's a generic part. I don't know. Thought I'd ask here before I speculate further.
