ok, so i dont know if i am posting in the right forum, but there doesnt seem to be one for the new IS 250. but anyway, i was looking at maybe buying one and was wondering if anyone knew of any companies developing aftermarket performance parts for it. i dont know if its too early for them to be doing so, but i was just curious. thanks for any infomation.

I doubt they'll have much for the motor. It's becoming a common motor in some japanese cars along with the 2GR motors, but I bet the 4GRs will take a back seat to the 300hp 2GRs... I like the 4GRs, I hope somone comes out with something for them.
