• Replaces worn rubber with 85 Shore A polyurethane for sharper turn-in and tighter rear-end control
• No machining, no spacers, no guesswork - direct-fit for fast-road or track-day use
• Retains usable ride comfort; not a race-only compromise
• Includes all front and rear suspension points - control arms, subframe, trailing arms, anti-roll bars

Not an OE replacement. Not a partial set. Just the full nine-kit Superpro solution, ready to bolt on.
