Correct. EDFC isn't available for the Solara base.
* Uppermount / EDFC compatibility
TEIN SUPER STREET DAMPER comes in two different kits; with or without uppermount (except some models). Pillowball uppermount with camber angle adjustment system is adopted for strut type (Ft), and reinforced rubber uppermount is used for strut (Rr), wishbone, and multi-link types. Kit with uppermount is fully compatible with EDFC. Kit without uppermount uses OE uppermount, therefore its pricing is very reasonable and affordable.
*Please note that both uppermounts and shock absorbers are not interchangeable between two different kits.
From the SS Damper Page
None of the kits come with the uppermount so we use the OEM. Kind of the weak link on our suspension area if we go crazy on the driving. I've heard that it DOES SUCK to change the settings on the rear coilovers since you almost need to practically redoing the rear suspension installation to just reach the setting controls. Probably ready to take a level up and head back to the shop to stiffen the suspension more but I'll wait until I get a whiteline FSB in my hands. I have about 2-3K of roadwear on my Tien SS coilovers and I can say is, they rock. Had the install shop drop it to 1.5" as I told them anywhere from 1.5" to 1.75" ish so yea. I could tell, if I lowered it anymore, my mudguards would be torn off if I take a speed bump fast or hit some crap on the freeway.(Arizona highways are nitorious for debris hazards). Just don't regret on simple upgrade suspensions. There are a few ppl here that have done the strut/spring upgrades then went Coilovers afterwards. Another 500-700 more of savings would be worth the for superior suspension setups, coilovers.
Tien SS good for street/minor autocross(but still can be good enough for hard) Though ultimately from many here, the JIC coilovers, FLT2?(I think) are the topline coilovers for our Solaras and would rock mostly in heavy racing. Daily driving is more comprimised though with JICs, Tiens have a nicer edge for it.
