tokico D-spec vs. Koni yellows.
 

like the thread says, which is better? im in the market for one of these two and want to know pros/cons etc etc. i track my car a bit here and there and have a track day coming up soon and hope to have one of these struts intstalled by then mated with my tein s-tech springs.

so... discuss plz

Koni for dampning. Tokico for easy adjustability...

overall... Koni

I'm looking for one of these set ups also. will be checking back!

MERRY CHRISTMAS!!!

Koni yellows without doubt

Tokicos have very good damping, but Konis are a bit better. Either will be a significant upgrade from stock shocks. Konis are the choice of folks looking to eek those last few tenths of a second out of a solo run or lap time. Not sure how they compare from a fading (overheating) perspective, which presumably is important on the track.

If you don't want adjustability you should also consider some FatCat Bilsteins. Shaikh will likely tweak the damping curves to match the aftermarket springs you run, but you'd have to contact him to be sure about that.

If you want the better track performance prevailing wisdom is the Konis are better. From a streetability standpoint the Tokicos have a wider adjustment range IMHO and are a better choice if you want to maintain a comfortable around town ride.

The Konis are not jounce adjustable and as such are pretty harsh over broken pavement and around town. Also I feel their range is pretty narrow. They are great on the track and I haven't experienced any overheating issues. They aren't very comfortable around town, even at the softest setting.

If you daily drive your car I suspect you will enjoy the Tokico's better.

konis > tokico anyday

yup have konis and love em

Or, go with the fact that the D-Spec is adjustable without touching anything but the knob. On 7 (softest) still better than stock. On 2 (one from hardest), great on track. Others might be a tad better, but not across that whole highway, street, track range without having to take the rear shock out to adjust it. D-Spec is the only one I found that lets you adjust the rears on the car. Gotta get the cables, but they are like $20 a set. You can also adjust the fronts without removing the stock tower brace.

I ran Konis for quite some time and loved them. The fact that rears aren't adjustable without removing them was a BIT of a drag but I knew that going in and accepted it. Besides, once I dialed in the struts how I wanted them, there was never a need for me to remove them.
The dampening on those things is amazing, I'd absolutely buy another set if I went back to a spring / strut combo.

can somone explain this "overheating issue" mentioned above? like the shock itself overheats? if that happens how can you tell and what should you do to prevent damage?

The movement of the oil in the shock will cause it to heat up. Overtime it will deteriorate and begin to loose it's effectiveness.

Yep, or the valves will get loose as well and they become useless.
Shocks are serious items, definitely one of the fields where you can't be cheap and pretend to "upgrade". Most coilovers under 1300$ are actually a downgrade from stock, one way or the other.
Their life, adjustability accuracy, specs will all be different from one coilover to the other, meaning that you'll get crazy trying to set them up properly.
Most drivers tend not to notice this kind of difference but if you put them on the proper machine (i can't recall its name) it becomes pretty obvious.

if anyone finds a deal on koni yellows... i need a set before spring!
