EDIT: I started out asking about Yellow Speed coilovers for the ST185--which I didn't end up going for, because of uncertain/apocryphal reviews and a negative review I found. But this ended up being useful as a coilover resource as of early 2022, so I retitled it.
Earlier on, I was looking at coilovers, and was looking at the Yellow Speed products available for the AllTrac: https://yellowspeedracingusa.com/collec ... -Trac-1992
In short, there are three possible outcomes: Street, Rally, or Track.
For street application, Yellow Speed has three different products:
The Dynamic Pro Sport Coilovers can achieve 50-100mm (2-4") drop in ride height, and reasonably stiff springs (7k front, 4k rear), which is about equal to stock springs. They state "This suspension system is ideal for daily driving and occasional track use."
The Inverted Pro Street Coilovers are similar to the Dynamic Pro Sport Coilover, with 7k front and 4k rear springs, but with inverted monotube design said to prevent premature failure of the seals.
The Super Low Coilovers can achieve 80mm to 130mm (3-5") drop in ride height, and feature stiffer springs (8k front, 6k rear), with camber plates for the front springs. They note that "the SUPER LOW kit will increase ride handling but may also have a negative effect on comfort." Slamming your ride can have that effect, yes.
For track application, Yellow Speed has this:
The Premium Competition Coilovers feature very stiff springs (14k front, 12k rear) and I am guessing these would be distinctly unpleasant on the street. But for a track car, these would be the weapon.
For hauling ass on gravel, Yellow Speed has this:
The Dynamic Pro Gravel Rally Coilovers feature softer springs (5k front, 4k rear) and are overbuilt to withstand the special rigors of rally driving. I imagine these would feel soft on the street, and the ride height can be raised 2" or more. There is no discussion of how little ride height can be raised--I believe the assumption is that higher ride height is desirable and so the minimum would be overlooked.
For my own personal use, I am considering the Dynamic Pro Sport Coilovers. Has anyone gone with the Yellow Speed products and if so what was your experience?
