Obviously the Tokico's were an expensive purchase. But, I still fail to see the logic behind the purchase. Why not spend a few dollars more to get the Koni's?
You forgot to call ZZYZX and ask them what they use for inserts. Koni 8611's.

They have multiple national championships to their credit along with 6 trophies alone from the 2007 Nationals. Koni NA also provides onsite support @ all national tour events and nationals. ZZYZX also supports grassroots competition with sponsorships, knowledge sharing (setups, rates, valving) and eventside support. They are THE Subaru/Evo suspension answer. Unless, you have 10+k to spend on remote reservoir Motons.
The reason why I keep posting is because why not just do it right the first time and spend the money once? Even if its just a simple ground control sleeve setup with koni inserts?
