Whilst I was there I had a few decisions to make, like do I put the extra radiator in? It seems a no brainer to do it, especially since it's very likely to find itself out in the UAE on the track at 40c.
The fuel tank, the donor car is a C4S, so the fuel tank is different and I've opted to have a bigger one now it's being converted and I have the extra space to fill.
And another thing was the suspension, the wheel carriers were a surprise, Marc had laid out the choices I had on the bench so I could pick them up and actually feel the differences, the RS ones were ridiculously light compared to the C2 or GT3 ones, they're expensive and arguably not necessary but from what I've read they're a very good upgrade if you have the budget. Once I'd actually held them in my hands and felt the differences it again felt like a no brainer, so I'm going with those. From what I read it changes the steering feel from 'great' to 'telepathic', so it's a more expensive option but hopefully I'll feel the benefit.
It seems like regardless of car colour, everyone goes with red seatbelts, the guys in the shop said the same, even with their green car they went with red seatbelts, apparently to match the calipers. But my wife put her foot down and wants blue seatbelts and I'm not bothered enough to argue against it, in fact it will probably look less busy inside, the red might be too much with the blue cage and blue accents on the dash.
