looking for sites for performance parts

alright here is thething i am trying to help out my cousin with his newcar it is a 2008 ford focus 2.0 and he is looking for some good performance parts sites any help would be great

summitracing.com, jegs.com, stylinconcepts.com. Also if your gonna run performance you'll want good oil. I sell Amsoil and there is no doubt in my mind its the best synthetic. Less friction you can have in the engine means more power and better gas mileage. Good luck to you.

focussport.com

oh yeah and cosworth, and ford racing... or sell it and buy something reliable... just a thought
