This is a post at www.m5owners.co.uk where M5 Dave did numerous modifications on his
E39 M5 to come up with his dream car.

All the mods are done by CA automotive. It includes:

• Stop tech big brake kit,
• Rogue Engineering short shift kit and tranny mounts,
• Rouge Engineering power pulleys,
• Maf sensors and
• Temp sensor relocation kit,
• Active Autoworks ram air induction kit,
• Eisenman quad racing level exhaust and supersprint x pipe,
• Ground control fully adjustable coilover kit,
• Storm motorworks billet handbrake and gearknob with custom engraving,
• Mk4 monitor and sat/nav and new wheels.

If this list of mods makes you breathless, I presume the car will leave you breathless too.
