Almost all street cars come from the manufacturer with an anti-roll bar as it is a common part of modern suspension systems. However, they are designed to be overly soft for maximum comfort and to add understeer. An anti-roll bar does exactly what it says by reducing body roll in all situations. Every Dinan tuned anti-roll bar is built and tuned specifically for each BMW chassis. Lowering the amount of body roll keeps your BMW more level than stock and reducing understeer (while still allowing just enough body roll) to improve mechanical grip. This improvement gives the driver a much more planted and confident feeling in every corner.
The 15.8mm rear Antiroll Bar may be added to the Stage 1 Suspension System for those who are building their high-performance suspension system in stages. The Dinan rear Anti-roll bar is 118% stiffer than the stock 13mm rear bar (please see listing below for full breakdown of Dinan rear anti-roll stiffness ratings). The matching Lightweight Tubular Adjustable 28mm Front antiroll bar should always be installed as well for proper balance on RWD vehicles equipped with D120-0530, 28mm Front Swaybar and one of the following; Limited-Slip Differential or rear tires that are wider than the front tires by 20mm or more.
E93 328i = 13mm or 15mm (sport) (Dinan 15.8= +118% or +23% stiffer)
E90 325i, 328i, 330i, 335i = 13mm (Dinan 15.8 = +118% stiffer)
E82 135i = 11mm or 12mm (Dinan 15.8= +326% or +201% stiffer)
E92 328i, 335i, 335is = 13mm (Dinan 15.8= +118% stiffer)
E90/E92 335xi = 15mm (Dinan 15.8= +23% stiffer)
E93 335is = 15mm (Dinan 15.8= +23% stiffer)
E82 128i = 12mm (Dinan 15.8= +201% stiffer)

Manufacturer's Warranty — Dinan
▾
Manufacturer's Warranty — Dinan
Dinan warrants its Performance Products to be free from defects in materials and workmanship, and the term depends on the car. If the vehicle is still covered by the original manufacturer's new car limited warranty (4 years or 50,000 miles — 80,000 km in Canada — from first retail sale; US and Canadian specification vehicles only), the Dinan part is covered for the remaining term of that new car warranty, and an Authorized Dinan Dealer repairs or replaces the defective Dinan component without charge for parts or labor, including any original manufacturer component directly affected by it. If the car is out of its new car warranty, Dinan Performance Products carry a 2-year, unlimited mileage warranty from the date of original purchase; labor is reimbursed at the dealer's standard flat-rate, but repairs to affected original manufacturer components are not reimbursed. DINANTRONICS Sport, DINANTRONICS X and DINANFLASH handheld units are 1 year, unlimited mileage; refurbished products are 90 days; and racing-only parts are guaranteed against defects in workmanship only — they are not warranted against wear or failure and may affect the BMW factory and emissions warranty. Dinan's warranty is transferable when the vehicle it was installed on is sold. A lawful invoice as proof of purchase is required, and the defective part must be returned to Dinan for verification before any adjustment. Not covered: return shipping, towing and rental car charges; unauthorized modification of a Dinan part, or damage from using other manufacturers' products alongside Dinan systems; non-DCT clutch assemblies, brake rotor warp and friction materials; maintenance items such as spark plugs, filters, lubricants, fluids, coolant, drive belts and light bulbs; negligence, abuse or improper installation; engine damage from altering Dinan's original boost pressure; improper or contaminated fuel; collision damage; environmental damage, flood, fire or road-salt corrosion; and any vehicle operated in a competitive event or subjected to aggressive track conditions. The warranty is void if the VIN or odometer has been altered, if the vehicle was declared a total loss or salvage, or if it has been used in competition. Note that installing performance products may affect the vehicle manufacturer's own new car warranty. Because Dinan handles claims through an Authorized Dinan Dealer, if you bought it here, contact PitStopTuning and we'll file the claim with Dinan for you rather than approaching Dinan directly.
Warranty terms are set by the manufacturer and may change. Contact us if you need help with a warranty claim.
