Juat realised that the car being driven in the original post is not actually the car offered as the kit. Ant’s car used Alfa parts, not Mazda, The Spyder driveline is angled to fit, sorting the shifter issue, so I suppose the Mazda kit will be the same.
But in the driving video:
An NB isn’t going to sound like that out of the box.
And when you hear the original, you can’t help thinking “phoney”.
