Will v6 springs work on my 99 gt like the old 4cyl springs did on the fox body gt's. I mean by lowering it slighty and making it shift back and hook alot better off the line.
They will probably work, I mean people put cut fox body springs on their newer GTs... so the V6 springs will probably fit.
Whether or not it would improve performance I seriously doubt it. If mustangs performed better with V6 springs, then they would probably come equipped like that standard as im sure Ford would save money in the process.
