ok, the scenarios are this
front engined, Rear wheel drive, 750 kg car, 140 BHP, probably ( I'm guessing) about 65/35 weight distribution ( its a cortina ok!
)
pretty much everyone, inc me, seems to run single leaf capri 2.8 springs on the rear. 140lb
I run 500lb front springs and a 1" ARB, and the cars understeering slightly testing in the dry at Goodwood. I have 2 options, go to to 450lb springs ( free and easy as I have them) or go 7/8 or 3/4 ARB ?
other set ups I know on Loti Cortina are
600lb and 7/8" ARB
550 & 7/8
700lb ! 3/4 ARB
a few run soft, ie 350lb, but theyre slow !
My general philosophy is change one thing at a time so I think 450lb springs and test to see if its better ?
any one got an opinion or anything constructive to offer ? ( other than buy a proper car !)
