alrite so i got me crx a lil while ago and ive been saving money and over all i just wanted to kno how the ebay parts are, like if there good or just plain trash. im looking into strut bars, lower control arms, and headers. they are all cheap but are they worth it?

 

Instead of getting cheap ebay parts, I would save my money to get some brand name parts. They don't have to be the most expensive brand out there, but if you're looking for performance then that's what I would suggest.
I have a civic that came with an ebay header. When I put a new exhaust on, I had to cut and re-weld the header because it was too long. Even when it was the right length, it just didn't fit right so now my exhaust is obnoxiously loud.
That's just an example but keep in mind that cheap ebay parts aren't the best choice.
