The LWF setup is already itemized on the US PET. It turns out to be the exact same RS setup that has been in use for years. So still on the 996 GT3 board there are debates whether to do it or not, and here people will start a coop if there car does not have it..... Oh and it does make a big difference..... I know 1 US 997 GT3 is already upgrading to the LWF.
