Think carefully before you spend.
Work out what wheels you want and build around that,
Supers do have limitations for wheels
Dont buy cheap wheels and then be caught with having to go wide guards or nor being able to lower.
You are better off spending your $$$ on struts first as this will allow better wheel fitment.
If you want to go wider than 4 1/2" you will need narrowed springs.
hour glass springs are a waste of money.
Once you have put these in and lowered the standard cup and put new shorter inserts in you may as well have put propper adjustable struts in.
I am running 16" x 6" 50ET 205 50 series under stock guard with room to spare
Have a good look at the chromies/Empi 8 spoke etc and you will see they sit proud and you wont be able to lower porperly
Stock is 4 1/2" with 41ET (offset)
Sports option was 51/2" with 26ET
Use sports as your outer limit but with thinner springs you can go further in than stock

Stock wheels on a nicely lowered super looks HEAP better than mags with a 4" gap under the front wheels
