BMW Z4 · 2008 · N52B25
Oskar's Z4
A naturally aspirated straight-six with nowhere to hide the noise.
Shortened gearing, sorted suspension, and a body kit still finding its feet.

Shortened gearing, sorted suspension, and a body kit still finding its feet.
Oskar's Z4 runs the same naturally aspirated N52B25 straight-six as the rest of the N52 line-up — 218 PS and 250 Nm, nothing forced through it. A Rieger front end is already fitted, with the rest of the body kit staged and ready to go on.
Underneath, ST XTA coilovers and Powerflex LCA bushings sharpen the front end and add caster, while a Z4 automatic diff housing shortens the final drive to 3.64 with a Blackline helical LSD behind it. JR SL03 wheels keep the corners honest at just 8.3 kg each.
