I want to build my Hawk with a softer rear spring than that supplied with the kit (360lb/in). Having read the various opinions here, discussing with Guy and doing a few calcs on suspension frequency I would like to fit 250lb/in springs. Whilst it seems easy to source alternative front springs (2.25"ID) from several manufacturers/suppliers I'm struggling to find anyone who might have 4.5" rear springs in stock and therefore I'm looking at paying to have them made. Has anyone found a supplier who might have what I'm looking for? Or a real long shot, has anyone got a pair I can buy off them? 9"long x4.5"ID 250lb springs

Cheers, Keith
