I see all these cars with custom parts and was wondering where you guys get all your parts? What are some good sites? I'm talking about performance, not interior or exterior. Also, where can you get 5 point harnesses that can be equipped to the stock seats? I have seen them before, just don't know where to get them.

gives you information on it. reading in the second paragraph "They will not work with 1G Eclipse stock seats since there is no place to run the belts thru the seat backs. They work great on 2G Eclipses..."

other performance parts. look elsewhere for those.

 

What do you mean by custom parts? Just any performance part?

Here's a few of the places I got my stuff:

Maperformance.com
