Adjustable front spring perches are are essential for an E30 race car, but are also useful for dual purpose cars. You can set the ride height wherever you want, and change it in only a few minutes. The threaded sleeves sit on a machined collar (provided) which must be welded to the strut. The lower perch is threaded on it’s ID so you can turn it up or down to change ride height. Kit includes threaded sleeves, lower spring perch and weld-on collar. Note: Does not include springs or upper perch. Instructions here.
This kit is designed for use with 2.5″ ID springs, available separately. 2.5″ springs come in 25 lb. increments and various lengths. I suggest a length of either 7 or 8″.
