Ok, I do apologise for posting saying 8000rpm was a good place to drop the clutch.
In a standard R33 GTS-T, I would still recommend around the 5000-6000rpm mark as this will ensure that the tyres break traction and can spin up quickly and efficiently.
A burnout will take of the same amount of tread as travelling the same distance while rolling. The fact that you aren't moving anywhere doesn't make a difference.
Just a quick note to draggers who wanna warm tyres before running. Everyday street tyres are designed to operate most effectivly at a specific temperature. If the tyre heats to a point past this temperature, you will actually lose traction as the tyres have been slicked up.
I found that on street tyres, a burnout really isn't necessary as these tyres are designed to work better at a colder temperature rather than hotter. If you really wanna do one, simply a quick burnout without the brake would be sufficient.
That is all...
