Product Overview
Whiteline BMK013 Front & Rear Anti-Roll Bar Kit – Mazda MX-5 ND / Abarth 124 Spider (348)
The ND MX-5 and its Abarth 124 sibling are light, balanced roadsters, but on soft factory settings they lean noticeably on turn-in and can feel lazy changing direction. Whiteline’s BMK013 tackles that with a matched set of solid spring-steel bars that firm up roll control at both axles while leaving spring rates and ride comfort largely alone.
What’s in the kit
- BMF65Z front bar – 26mm, 3-position adjustable
- BMR94Z rear bar – 16mm, 2-position adjustable
- Four links (KLC205 front and KLC139 rear adjustable links)
- Four bushes, two saddles, two brackets, four lateral locks and twelve washers
Tuning the balance
Whiteline quotes the front bar at roughly 45%, 70% or 100% stiffer than standard depending on the hole used, while the rear bar runs from slightly softer than standard to around 15% stiffer. That range lets you dial out understeer for fast road driving or tighten things further for track days without changing the whole set-up. Because the kit is engineered as a pair, Whiteline recommends fitting front and rear together rather than mixing with factory bars.
Fitment
Listed for the Mazda MX-5 ND roadster and RF (1.5 and 2.0, 2015 onwards) and the Abarth 124 Spider 348 (2016-2019). Some US listings also include the Fiat 124 Spider; please check with us before ordering for a non-Abarth 124.

Fitting advice
Whiteline puts installation at around three hours with the car safely supported on a ramp or axle stands, and it can take longer if you’re new to suspension work. Set both bars to the middle or softest position first, road-test and adjust from there. A four-wheel alignment check is recommended once everything is torqued to the factory figures.
