Just going to add this place to the list as well http://cbrd.mybigcommerce.com/

 

I sell a lot of parts at very competitive pricing and fast shipping. email me at tom@tscomptuned.net if you need anything. My website is not fully setup for parts because i'm to busy with tuning and customers cars in general.

Any vendor on this site should be a good option though regardless.

 

I no this is a tad old but MapPerformance all the way iv put a few orders in with them spending Probally around 12000$ there customer service shipping is amazing they'll help you out and tell you what's best for your build STM is also really good with customer service and shipping. Both are competitive pricing and work with your needs. Thanks guys 👍
