JZA80 Suspension setup

[ed]

just thought id pass this on...

got all the numbers tweaked on the car today, and yeah, pretty awesome to drive. not been tracked yet, so take these numbers only as a guide for an agressive street setup. caution, due to the lack of toe, it is less able to pull straight on the freeway and requires a bit more effort to drive, but cornering is sensational

front:

camber: 1.5deg
caster: 5.0deg
toe: zero

rear:

camber: 1.3deg
toe: zero

i started with the numbers suggesting in the attached hi perf imports (2000) whiteline article, and then pushed things a little further. am very very happy with it.

ill update once the swaybars and new shocks/springs go in

I must say I've noticed you all over the Supraforums lately, took me a while to figure out Corona had bought your MA61 and you had a JZA80 That's a good article too, thanks

and another thing with springs...

after having a few issues with front inside lift off, ive upped the rear spring rate to the same rate as the fronts to reduce weight transfer up that end.

i probably should have some springs made, and will eventually do that, but for now, the increased rate is pretty marked improvement..
