Reviews I've read do say the engines aren't all that and they could do with abit more power.
Although there are compromises the s2k was built with performance in mind.
50/50 weight distribution, special cross beam floor thingy. They are also technically mid engined. LSD, double wishbones all round. External reservoir dampers on the rear.
Only real compromise really is the roof IMO,
But this is about the brz/gt86.
Not really read up about the specs on the car but heard they have a low centre gravity?
