A wide range kit has been installed. Front 225/40 r18, rear 255/4018. Good grip, it was tested on a mountain pass when passing at the speed of a stone on the road. But as it turned out there is a big minus in terms of acoustic comfort. On the rear axle, the rubber is not audible at all; in front, when speeding up from above 80 km / h, a strong hum appears. The entire suspension is in perfect condition, the balance on all wheels is set to Zero, the camber / convergence is also perfect. All wheel bearings are normal, the gearbox and driveshaft are normal. But the noise in front is like the operation of an airplane turbine.
