How does the ride quality compare? Loss of the adjustable dampers is the main reason I did not go with anything other than GC.

It feels amazing really grips the corners and roll is diminished greatly best decision yet, oh and you don’t lose sport mode how some have said. Just the dampers.

Gotcha. I don't know how intrusive the "damper error" is, but I know D2 has an error canceller in the works.

Basically this pops when the car moves, once cleared the info bubble stay up. It doesn’t flash up again until next startup.

Gotcha. The info bubble would probably annoy me a bit, but it wouldn’t be the end of the world.

its sounds about as annoying as the TPMS when you put off re-calibrating it all the time. haha

Man your setup is Fire, what are the wheels and specs if you would be so kind? Also, with the ADS warning light do you notice that sport mode functions the same minus the ADS? Im wondering if that would mess with Ktuner map settings etc

I was on eibach for the longest no complaints just officially upgraded to d2 coils and I’m loving every second of it. Of course to get the dash light but the module should be out soon.

Esr 18x9.5 +35 225/40 nope everything works fine basemaps,sport mode, etc. all is functional and no alarms constantly going off only on startup and that’s it. Small bubble goes unnoticed at this point. More pictures of my build on instagram more than welcome to poke around in there tons o goodies haha

Thanks a bunch for the reply, i am looking to get 18x9.5 +38 and use the stock tires for now since the car has 600 miles. wanted to get goils and went with D2 springs for now while i was researching fitmit and waiting for them to make the ADS light eliminator. Did you have to roll your fenders or anything to get those to fit? or was it perfect. Maybe its worth it to get the +35 instead of +38. Little less poke maybe. Thanks again!

No modifications needed apart from stretching the tires a bit, was the look I wanted so it went nicely. Stock tires are 235/40 I’m running 225/40

Right on man, thanks!

Any news on a ADS light eliminator and other coilovers kits for Sis? The D2 coilovers look good. Do you know what the springs rate are? I was surprised to hear that GC didn't recommend a higher rear spring given that it's a divorced setup and also a FWD car. Wondering if there are more autocross/track focused coilovers out there over D2.

HKS has one out or coming soon, it is VERY expensive. $300-500 if I recall correctly.

Wow. $300-$500 to surpress a light?! Screw that. I wonder if someone could just figure out the resistance of the shocks and then plug a resistor into the pigtail of the ADS system and voila.

Wonder how many companies will actually come out with a coilover kit for this gen Si. Seems like a stupid light is holding the market back. Might just go the Eibach Pro-Kit lowering spring route and maybe camber plates. But then the stock spring perch and the springs themselves are going to keep you from getting much negative camber up front anyway. Damn it, might just have to settle for pulling the shock tower pin, camber bolts in the lower holes, and crash bolts in the upper, and then just maintain the stock strut mounts. Hopefully get close to -2 degrees.
