Thanks for the responses Joules and Boss Wrench. After being gone for 10-15 years it's great to see you both still here. @joules that was my suspicion on the Aldans. Thank you for confirming. I won't be buying Aldans.
As for the Carreras, can they be rebuilt? I was told by QA1 that the non-adjustable version (ride height only) that I have on my car they were basically throwaways. Mine feel like rocks but maybe that's the springs. Sounds like I should be looking into Carrera Adjustables.
Which ones are you running, Joules? (model/length) Would the spring rates be the same for a narrow body vs your GT5?
Other than SAAC are there any additional options before moving to an external reservoir Moton type shock?
