Ducman69--That thread from P-51, he states that he couldn't get it to work. I have been riding on CUT stock springs, for a year now!!
They are only cut about 1.5 coils. loweres the car 1.5 inches. This is perfect, not super low to screw up anything. I had the Sportlines on before, and those SUCKED THE BIG ONE!!! WAY too soft!
The problem with cutting is, you can't just cut EXACTLY 1, 2 or 3 coils, since after the fact, they will not line up, that is why I had to cut approx. 1.5 coils.
When I was taking Sportlines out to ship them, I used them as kind of a guideline or template, I lined up the bottom, then cut the top at the same spot where the Sportline finshed.
This worked perfectly. I had tried prior to that to just cut 1 full coil, but that didn't work, the spring did not seat in the shock right!
