H&R Touring Cup Kit – BMW 128i / 135i / 135is (E82)

OVERVIEW

An H&R Cup Kit is a complete suspension package: springs and shocks designed and engineered together as one system rather than mixed from two catalogs. The Touring Cup Kit is the comfort-biased version — a moderate drop with a progressive spring rate, aimed at owners who want lowering, improved ride comfort and better body control from the same kit.

On the E82/E88 1 Series that works out to roughly 1.8 inches at the front and 1.2 inches at the rear on the 128i and 135i, with the factory-lowered 135is dropping considerably less. Lower center of gravity, less body roll, sharper turn-in, and a stance that still clears a normal driveway.

H&R builds every spring in-house in Germany. The wire is a special 54SiCr6 spring steel, cold-wound and then shot-peened to increase service life by more than 200%, so the spring resists settling and sagging over time. Each spring is 100% tested before it leaves H&R's ISO 9001-certified plant, and the range carries TÜV approval.

TECH RESOURCES

Additional Parts Required

• Four-wheel alignment. H&R requires the alignment to be checked and reset after installation. Budget for this before ordering.
• Professional installation. H&R states its springs and suspensions should be installed by professional suspension mechanics only.
• Bump-stop trimming. Check the trim chart in the H&R Technical Information Sheet linked below for this kit number before assembly.
• Confirm your car is not fitted with EDC / adaptive dampers. H&R does not list this kit for EDC-equipped cars.
• No matched dampers need to be bought separately — springs and shocks are supplied together as one engineered package.
• Optional: replace worn strut mounts, bump stops and dust boots while the struts are apart.

Installation

• H&R Technical Information Sheet (PDF) — ride-height measurement procedure, spring orientation and markings, bump-stop trim chart by kit number, and post-installation alignment requirements.
• H&R technical FAQ and installation guidance (hrsprings.com) — manufacturer installation questions and answers.
• H&R does not publish a vehicle-specific printed installation manual for this kit; installation follows the factory BMW suspension service procedure. Contact Speed Logic if you need help sourcing the procedure.

Notes

• Lowering figures are H&R approximations and vary with the car's options, wheel and tire package and starting ride height. Fitment for a specific coupe (E82) or convertible (E88) build should be confirmed with Speed Logic before ordering.
