I am on budget right now, I never said anything about svt springs. I am able to get svt damper kit with rear sway bar for $180.
How is cutting to shorten the rod and welded properly will fail? If u shorten 1 inch of rod and lower the car 1 inch, the damper travel itself stays same. Svt shock absorbers are more stiffer and it can be lowered to 2 inches therefore cutting the rod will give me 3 inch or more clearance.
I have other vehicle so I am able to bring the progressive lowering springs and svt shocks to my work to machine and rethread the rod or cut and weld. I am going to cut the springs with band saw or mill it.
