good morning
I have been keeping myself up-to-date with their most recent build, the XK8, and it's performing quite well on the track. There's no doubt that you are in very capable company with Swallows. It does sound like you have taken quite a methodical approach to this particular build, and I am quite eager to see the different stages of this project take place
Along with the carbon wheels, gearbox, and obviously increased engine power, have discussions taken place in regards to further weight reductions, suspension upgrades, and increased braking capabilities? I would love to hear what you potentially have in mind for these areas of the build.

Viezu technologies have taken the car as far as they can. although she already has upgraded breaks, and I’m not a fan of carbon fiber, unless you are racing, which I don’t really intend to do with a cabriolet it would be a bit silly.
I took Tom‘s advice on the suspension upgrades which he said just replace old for new because I wanted still drive in and out of cities and apparently the OEM suspension is the best product possible according to Tom for what use I want

now, since Tom recommended the brake upgrades pads and rotors basically
The only improvements left are the gearbox pop shaft, some maybe porting of the engine changing of the heads, however, most of what we will achieve will be the gearbox and the lightning of the wheels.
I do hope that explains everything to you and thank you for not being a skeptic

Anything to reduce non-sprung weight will provide quicker acceleration. Carbon fibre wheels can come in under 10 pounds apiece vs forged wheels at just under 20 pounds each (nearly half the weight of OEM alloys wheels), however they're quite delicate and expensive, as much as $40 grand for a set. Carbon ceramic brakes are less costly than carbon wheels and can save you the same amount of non-sprung weight over steel discs so why not do that???

so I totally agree with you, however, due to my driving style and In-N-Out of London carbon, ceramic breaks are not conducive to that they need to be warm at most times. Otherwise they become almost useless I was recommended. Tarox F2000 and Strada pads all round.

Thanks good to know

I’m a bit flummoxed because you talk about spending massive amounts of money to make the car lighter and faster but you’re saying you don’t want to save loads more weight with carbon ceramic brakes because you drive the car too slow to use them….
I’ve got the Swallow’s Tarox discs with Pagid pads fitted to mine and quite impressed with their performance over the previous AP Racing discs

I personally phoned Jaguar and asked them. They said they do not recommend them because they are pure summer tires and I were to hit a puddle. It would be like driving on ice, but that was the absolute maximum size tires that could be fitted without any adjustment now, the car will be sent to swallows who will change them for racing rims and do they magic to the car I have complete faith in swallows I mean come on they race jaguars although I have been told that the gearbox changed they did to manual was to a 4.2 L not a 5 L supercharged, and I’ve been given another telephone number to speak to them and a costing of about 50,000 pounds after swallows are finished with it however, that does not matter as long as I end up with the fastest fully Cabriolet car in the world.
Hennessey Performance Engineering now holds the record for the highest top speed achieved by a convertible vehicle. In 2016, an automobile with 1,800 horsepower and a price tag of $3 million hit a top speed of 265.6 miles per hour.
