Elise/Exige springs (F and R)

Brought some used nitrons for my S1 Elise with springs that are too stiff for my needs (more suited to race or track use) at:
Fronts – 750lb/in and 5in long
Rears – 1000lb/in and 6in long

Suits 2.25in spring perches which I believe most of the 40mm and 46mm nitrons are.

They’re unmarked black and likely only a few hundred miles old based on the previous owner.

They’re quite heavy but can ship at buyers expense or of course collection is welcome (Abingdon, Oxfordshire)
