da hat sich jemand die Mühe gemacht die Unterschiede zwischen den beiden Modellen herauszuarbeiten

| This is my attempt at compiling a semi-comprehensive list of mechanical differences between the GR86 & BRZ. Sorry, some of this is probably repeat info. Feel free to correct any misinformation or add to the list. Driving impressions: GR86 is sharper, direct, agile, more playful & slides easier, but is more difficult to hold a drift (more on this below) BRZ is more stable, linear, and predictable (easier to handle) Front knuckle: GR86 is steel (same as previous gen) BRZ is aluminum (~1.5kg lighter per corner) Front sway bar size: GR86 is 18.0mm solid BRZ 18.3mm hollow Rear sway bar mounting: GR86 mounts the rear sway bar to the subframe via bracket (same as previous gen) BRZ mounts the rear sway bar directly to the chassis so that it's not impacted by the subframe bushings. BRZ also has an additional brace across the trailing subframe mounts to further increase rigidity. Rear sway bar size: GR86 is 15mm solid BRZ is 14mm solid (but mounts to the chassis & has additional subframe stabilizer brace to increase rigidity) Rear trailing arm bushings: The rear trailing arm bushing is more compliant on the GR86. This allows some compliance for toe out during compression. This makes initiation of a slide easier on the GR86, but it makes it more unpredictable and harder to hold a drift. This comes at the cost of mid-corner stability and bump/snap oversteer. The BRZ uses stiffer bushings to prevent geometry change under load making it more stable/predictable. Front springs: GR86 Front 28Nm/mm BRZ Front 30Nm/mm Rear springs: GR86 Rear 39Nm/mm BRZ Rear 35Nm/mm Damping: "BRZ is a saturated type that does not increase the damping force too much in the region where the input speed is fast, while the 86 has a linear damping force characteristic." EPS: The EPS tuning is supposedly slightly different, but they both share the same 13.5:1 steering ratio. Throttle mapping: GR86 has more aggressive throttle mapping BRZ is more linear as you would expect from an NA engine |
