I have searched for this, and seeing as how I am unable to find the info, it means I probably did it wrong b/c I swear I read something about this and can no longer find it... BUT!... I will ask in case someone has the info handy:
Are the Espelir GT springs linear or progressive rate?
I know the rates are like 280 lb/in. front and 230 lb/in. rear, but... progressive/linear??
My gut says linear b/c otherwise they'd list a range, but -sometimes- you see stuff listed incorrectly b/c no one bothered to ask or clarify, or it was just an oversight.
