Two totally different goals.
The STR.Ts are a mild upgrade over stock dampers. I'd class them about on par with a Tokico blue.
Yellows are a high-performance adjustable damper. I'd recommend these if you're racing in an arena where corners are involved.
If you don't know the difference, you probably don't need to spend the extra money for the yellows.
If you don't know what adjusting dampers does, I recommend not having adjustables.
Oh I know, and I understand all this completely. I guess I should be more clear. I'm not an expert, but I was under the understanding that a damper had an optimal operating range based on height. So at stock height they were designed for they had freedom to move around, travel, independent from actual fluids, etc. When that same damper is compressed, say when a vehicle gets dropped, it no longer can work well because its already partially compressed and isn't designed to be working under already compressed state. This applies to the non adjustable, like the STR.T. Are they made for stock height and "mild" drops, then they are designed for that height, and will follow the same rules in decrease in effectiveness or operation when compressed... rendering the improvement null.
This brings me to the Yellows, do they follow the same principle as the STR.T, or can they work independent from this factor? Do they work well compressed with this kind of drop? Will they increase ride quality? I have the Sportline drop, which I've seen referred to as an "extreme" drop. I loved the ride in my stock Brembo set-up, but now that I'm lowered, it bounces a lot more than usual on rough areas of the highway. I want something I can put in that can remove the bounce and firm up the ride. I'm also putting in a Watts-Link setup at the same time, as I will be AutoX'ing alot more soon. So I need some stiffness sometimes, and when driving on the street, firm but not bouncing. I just don't want the damn thing to bounce, lol.
I hope this clears up anything I might have misspoke on.
