Racing BMW specialist Race Performance Modified has this month lifted the lid on its latest piece of motorsport engineering – a fully-adjustable coilover suspension kit for the Z4.

This kit is designed purely for serious track enthusiasts. Main features include hardened piston rods, that are hard chrome-plated for strength and durability; multi-lip sealing; lightweight billet alloy components and a nickel-coated body to provide the best anti-corrosion finish possible.

That’s not to forget that these 36-point bump and rebound adjustable coilovers also come with a two-year warranty.

These motorsport coilovers are priced £825, but if you’re after something slightly less radical (in other words, something a bit more comfortable for road use) RPM has another kit priced £595. For further details visit: www.raceperformancemodified.com.
