Kaspa, that is a hard question to answer, not sure why we do anything but here goes.
I aim to build it as homage to the racers on the 60s. Complete with period 15” wheels. It will see mainly street use however it will get entered in club and entry level motorsport in an attempt to cure any cravings for speed. If i was going to build something for the circuit only i would probably build a sports sedan like Craig’s E30 for wheel to wheel events or even get myself an old F3 car as for the dollars they are hard to go past with the amount of downforce you get.
The 15” tyres seem to be larger in diameter than most of the modern 19” tyres, so that is a good start from the gearing perspective. I am worried about how comfortable it will be to cruise around in on the highway. Some of the things i would like to do with the car in the future are:
Complete laps of Philip Island GP circuit at speed. I think cars like a 996 GT3 top out at around 300km/h here approaching turn 1.
Complete a lap of Bathurst at speed, just to say ive done it. Bucket list stuff!
Given that there is a lot of hype around the speeds achieved on the Mulsane in Lemans, i would also like to tick of the 200 Mph barrier, maybe at one of the airport runway events.
Maybe even have a go at a few hill climbs/club sprints just because
From an acceleration/braking perspective, i’m interested to have a go at getting a 0 - 100Mph - 0 time of less than 10 seconds. I know when Ultima did this they were starting in 2nd, changing into 3 and then hard on the brakes. Not sure if they used a G50:01 or a G50:50 (G50:52?)

Thanks to whoever posted the link to the gearbox spreadsheet that i found here. Hope it is ok that i have added to it.
