Hey guys I'm looking to get a coil spring after I test what spring rate I need (using a borrowed spring).
I found this vendor on taobao that makes custom ti springs for a good price (they specify mtb too).
I don't really care about the qualities of ti, mainly just cuz it looks cool.

Their page shows the spring building machines and shows a press for them to test the spring rates.

Haven't seen any negative reviews.

Think I can trust it? Should I give it a shot?
