Back in the GD chassis Impreza days you could get STI Pink springs and adjustable fixed perch shocks (KYB) and coilovers (also KYB) from your local dealer. Lots of other STI bits too. The springs were pretty good, the shocks and coilovers...not great. I'd be happy with a quality non-adjustable part instead. Little surprised they went with Sachs instead of Bilstein for the tS just based on history but...:shrug:.
MINI had adjustable Bilstein coilovers standard on their GP2 Cooper edition. It would be pretty badass if Subaru would do the same, but I wouldn't expect that anytime soon.
This tS does look very cool. Needs real recaros though.
