Not sure what the FP springs are but here's some stock numbers... the base GT500 front springs that I just installed are 251 lbs.How do the Ford Performance front and rear spring rates compare with OEM Mach 1 HP Spring Rates? OEM HP spring rates and roll rates seem pretty balanced on the street just wondering if the Ford Performance option is would be a better choice for track use?
| PP1 w/o MR | Mach 1 | Mach 1 HP / PP2 | |
| Front springs | 165 lb | 194 lb | 211 lb |
| Rear springs | 728 lb | 657 lb | 742 lb |
| Front sway | 32.0mm solid | 33.3 x 5.0mm wall (JR3C 5482 DA) | 33.3 x 5.0mm wall (JR3C 5482 DA) |
| Rear sway | 22.2mm solid | 24 x 3.6mm wall | 24mm solid (JR3C 5A772 DA) |
