bout to get a gsr swap and was wondering if instead of gettin a aftermarket flywheel or should i just get my gsr FW and get it trimmed down and a machine shop????? is there a real big difference for my buck?

 

It just depends, I've seen aftermarket wheels that don't hold up to stock lightened that work very well. Then I've also seen the opposite of both scenarios. If you have a machine shop that knows how to lighten one properly while keeping it balanced at the same time for a good price, then I would just do that. If you want something really light, then aftermarket is the way to go - shop around though.
