Just thought this would be relevant to the people on this thread talking about "their version" of what the STI should be or about factory-installed (and warrantied) upgrades. Seeing as whatever upgrades Subaru may want to factory-install on their BRZ likely has to be okay-ed by the largest stakeholder (Toyota) in this joint project, here are some words straight from the horse's mouth:
"The philosophy of the 86 is that it is an open concept," says Mr Tada.
The conventional way is for the carmaker to produce a car and call it perfect, which means the users don't have to or can't do anything else.
For example, if the rims and tyres are changed, the manufacturer's warranty is void.
Instead, the 86 was created as a car with the potential to change into something the customer wants it to be.
"Why? Because if you ask 100 people what you think of the car, you will get 100 answers. They all have different views," he said.
Hence the open concept, which will satisfy customers because the car evolves with them and make 100 people's dreams come
true."
