A wheel forged from billet...well, this is a contradiction. Since forging uses liquid alloy, the second it is melted, it doesn't matter whether or not it was a billet as the inherent structural properties you get from a billet dissapear. Obviously, these will be replaced with the forged properties.
Forging doesn't involve liquid (or molten) alloy. It involves taking a lump of metal and plastically deforming it into the shape you want, ususally when its hot but certainly not molten.
By plastically deforming it you stretch and elongate the grain structure which is what makes forged products stronger than cast. Porosity is not that much of an issue in a proper pressure die casting, its purely the grain structure in the forged part that allows the wheel manufacturer to use less material to get the same strength.
A proper, fully forged wheel like the one in MB's second video is forged and then spun into the final shape. There is minimal machining and what machining there is won't
affect the strength of the wheel or the grain structure.
I'm not commenting on whether Rota wheels are any good or not, but there is no doubt that a properly designed and manufactured forged wheel will be lighter and stronger than the equivilent cast wheel. But they will obviously be more expensive because the tooling required to forge the wheel alone is way more expensive to make than a die casting die.

Found a seat that'll fit the S2000 today....only problem now is the completely ridiculous amount of leg room :lol: Anybody know any extremely short ass drivers?!! The pedal box despite being compact in design, and pushed as far back to the bulkhead as possible, leaves even me at 5'9" tall feeling a little uncomfortable just sitting in it!
Where do I sign?!? Short ass driver here!!! Lack of racing licence may be an issue though...

Apologies for the bad phone pics and the mess around the car (car is being moved into its rightful build area shortly, (just in a store room at the moment) bodykit arrived today so a few pics below of it quickly taped to the car. First impressions are that it fits very well and the quality is very good for the price. Many thanks to Showoff Imports for their help with this acquisition (www.showoffimports.nl). Painter will be in shortly to get moving with it, just need to finish off a few addition bits of shell work first:
