I have a 509 from about 30 years ago that a friend ran for 2 seasons of bracket racing.
I don’t know what he ran for springs, but probably the 933 springs, which are a pretty high rate spring, that don’t have a lot of extra space til coil bind if installed at the stock 1.860 installed height and opening to .500” lift.
If the installed height is a little short, I can see that leading up to accelerated wear.

It was given to me, I looked it over quick....... saw nothing obvious at that time.

If I get a chance I’ll measure it up this weekend.
