I'm on the same path
@Krabby. I didn't take the factory winch option when I ordered. I did order the roo bar. My vehicle came with the green dot front springs. That's the softest spring in the range.
I don't want (or need) to do a lift but I will add an aftermarket winch and bar at some point.
I just picked up a set of red dot springs off another owner who has done a lift. Ineos fitted the red springs to his Grenadier with winch and roo bar so red is the matching spring for that combination.
Green is 1364 to 1417kg.
Red is 1417 to 1470kg.
I'm sure you could pick up a set of red or even blue front springs from a forum member if you put out a request.
