458gt3 body kit for 458 spider

Hi this might be a crazy idea I am looking at doing some tweaks to my 458 spider lowering springs aftermarket exhaust and changing wheels which is no big issue and easily reversed.
But have seen a very nice 458gt3 conversion lights3flag swiss.
which brings me to the question before I make such changes are there such kits available (who from) and what sort of costs might be involved?
Just to add this will be a rad car and no rear wing will be wanted.
Thanks for any info and advise kind regards.
