String Theory Garage will be closed to the public from Wednesday, 29th July to Thursday, 6th August for our annual shutdown.
If you need to get in touch, please leave us a voicemail or send an email. Our team will happily get back to you when we return on Friday, 7th August.
Shopping online? Don't worry! Our online store will remain active! We hope to ship orders placed for in-stock items as normal during the shutdown. Anything else will be dealt with upon our return.
Thank you for your understanding, String Theory Garage Team
Eibach Anti-Roll Bar Kit (Front & Rear) — BMW M4 (F82)
Springs and dampers control how the car moves up and down — the anti-roll bars control how much it leans. Eibach's Anti-Roll-Kit replaces the factory bars with stiffer, cold-formed steel items that cut body roll and sharpen turn-in without touching ride height.
Pairing this with a Pro-Kit or Sportline PLUS spring upgrade is the more complete way to sharpen a car's handling balance — ask us about combined fitting rates.
