The only ones that stand out above both these companies is ISC N1 and Fortune Auto. Both of these manufacturers are rebound adjustable only and can be rebuilt in the USA. They both offer custom spring rates. Fortune Auto goes as far as to offer swift springs as an upgrade.
For the price I still think Fortune Auto might be your best bet. Being made in Korea doesnt mean anything no. There are coilovers that are made in Japan that are bad quality. There are coilovers that are made in the USA that are bad quality. Where it is made is not a direct indication of the quality. Have you ever even been to Korea? Do you think Korea pumps out high quality products?
What makes the HSDs MADE for the track?
The soft spring rates? Or the fact that you have no control over either compression or rebound - only at the same time (which is terrible for performance) or is it because HSD offers no explanation of how their shocks perform? No shock dyno charts from HSD.
You do realize Fortune Auto 510 series coilovers provide a shock dyno chart for each of the 4 shocks that you buy.
I'm not hating on HSD or BC Racing or anyone but you have to get your facts right.
HSD is not the best. They are a great value just like BC Racing, Megan, KSport, D2.
In terms of build quality it is really hard to say for sure. I would say none of these guys are really that great. Unless the coilovers are milled and made completely in america using high quality steel there is no 100% way of knowing the quality of the actual metal in the coilovers.
We also don't know what oil HSD uses for their shocks. We don't know what brand of components are used in the HSDs internals. We don't know what springs are used, what bushings are used.
If you can prove my wrong I would be very happy because I research coilovers for fun.
