949 Racing Xida coilovers GT86/GR86

[Westen86]

You guys should be giving Blub to some professional youtubers like Matt Farrah or Speed Academy. You probably wont need the advertising, but to showcase what these coilovers do on an 86.

If you can't get a ride along or test drive or get a rec from someone experienced who you know and trust you are straight up relying on anonymous internet opinion, basic specs on the product, and past reputation. No solution is perfect for every user, odds are you'll be gambling based on reputation, budget, and some assumptions on what you think will work best. 949s got a great rep, lots of people will buy based on past experiences with their products, but nobody hits 100% customer satisfaction.

In an ideal world, you would have a car with a suspension soft enough that you can go over bumps and kerbs but stiff enough so that the car has no roll at all whatsoever. Usually impossible, unless the car's CoG and roll center are both at ground height, which is also physically impossible. So at the end of the day, its all a compromise and depends a lot on the car's setup, the tracks you drive at, and the driver preference and skill as well.

You are correct. Weight transfer, as a mathematical representation, does not even take spring rate into account. Even some of the stiffest race cars I've seen still have notable body lean, even though the suspension is not compressing. This becomes a function of your center of gravity, roll center heights, and track width. The whole car leans as a unit with the suspension. That's unavoidable unless your center of gravity is below your roll center(which is basically impossible).

Options
Custom spring rates, Hyperco


700/600 Hoosier 255/40/17 ~ 285/30/18
500/500 Race - Track or autocross focused, 40~100tw race or 200tw UHP
350/300 Sport - For high grip street tires, 200tw. Casual autocross or HPDE
175/150 Touring - Street comfort, not for 200tw or race tires

Looking at the spring packages from the 175/150 Touring rates vs the 500/500, I'm assuming that the damping was designed initially with the 500 lbin springs in mind (mainly track tire and performance focused). Then you tested to see what spring rates would produce the most comfortable ride to come up with the "touring rates" for the same damper sweep (at the lowest damping pressure setting)?

Seeing that the dampers are single adjust, assuming a rebound adjustment, how much of the compression damping is increased with the single adjust adjustments? How does it effect ride comfort? How different is the comfort-ability going form the 150 to the 300lbin springs?

Do you guys have anything set up with the sport spring rates at the shop to demo? I'd like to come check them out.

-We started by dynoing some OEM shocks and the Sachs.
-Then we drove the OEM and Sachs, determining what area of the damping needed to change to improve ride on the soft end and grip/control on the stiff end. -
-We then give precise damping force targets to Tractive for the prototypes.
-We then being on street and track testing with a variety of spring rates, tires, alignment settings.

Pure bred race shocks for pro motorsports have a narrow "sweep". Meaning the range from full soft to full stiff is narrow, steps between clicks are very small. Pro team take a shock engineer to the track and revalve as needed. With all Xidas, we expand that sweep and make the steps between each click much broader. The damping plots on Xidas are non linear for compression and rebound. Both sides are digressive. Rebound side steps are pretty linear. Compression side doesn't change much at all until the last 5-8 clicks towards full stiff where low (piston) speed force ramps up. We seem to be the only high end shock supplier doing this type of valving. That's how we can get good street ride quality and responsiveness but still have perefct race level damping. The tradeoff is the steps between clicks are larger on Xidas than they would be on say a Pirelli World Challenge car. The reality is nobody reading this has high end data acquisition on their 86 or is capable of discerning the tiny steps between clicks on a pure race shock valving profile.

Touring or Race is what we will offer. Blub has race rates on it now. Call or email to schedule a ride at the shop or see us at the track where we always
offer rides.

Nice solution for this very common issue for us enthusiast who rank suspension a priority but still want something versatile enough to be comfortable to commute on and still kick ass in the canyons and on track. Less of a compromise, except for the having to change out the springs part.

Will definitely come visit you guys. Thanks!

Had a great weekend of testing at Chuckwalla Valley Raceway. Goals were NA record and 86 Cup Mod class record, and Sonny & Blub achieved those goals. Lap times and video are found in Blub's thread here: https://www.ft86club.com/forums/show...&postcount=300

With that mission accomplished we put some of the top 86Cup and 86 Drive Challenge (Norcal) drivers in Blub so they could experience Xidas and the setup in general from the driver seat.

Mike Kang from CSG
Kevin Schweigert - 86Cup Mod class points leader with his Supercharged 86 on Tein SRC
Joe McGuigan - 86DC/86Cup Mod class driver, instructor, master of sportsmanlike conduct (thanks again Joe)
Tor Anderson - 86Cup Stock class driver


All drivers got a full session each in Blub. All drivers were separated by roughly a second, a testament to the drivability and forgiveness of the setup.

All commented at how stable Blub felt, particularly over kerbs and bumps. Tor's first words were "This is a HOOT!"

Any update on the active ones?

We tend to update only when we have actionable information. No ETA for 86 ACE at this time. Standard single adjustable still in final steps of R&D.

Any update on release date?

Same as our previous post, no ETA. We are eager to get these on the shelf and start selling them but until we have something firm, it's better not to guess.

Currently fine-tuning details with the camber adjusting chips and end link bracket.

Anything new?

[turbofan]

I promise we will post when we have more information regarding availability.

Pinky swear.
