50mm, none.
from what i understand.

To much castor will only cause heavier steering (or load on the power steering), some tyre wear and otherwise it's all benificial. Positive castor will give straight line stability at speed and dynamic camber when turning. I've got my commodore loaded up with as much positive castor as I can before the tyre fouls on the body, makes the manual steering heavy but stays stable above 200km/hr.

Yes, from the dick heads in most shops will tell you. You can get away with it, but 3-deg would be best for 50mm JB lift IMO. Then again, i would go 75mm spring's with castor corrected arms

I've built a race car that runs alot of positive castor based on what an entire series of race cars like mine are built like. Perhaps you should practice before you preach.

Sorry, grammar Nazi :P

And yes within reason of course but in this instance a lifted Jim is going to gain some negative castor over stock so a 2 or 3 degree bush won't be overboard. I run around 3.5 degrees positive in my fast car and I know some blokes who run 5 degrees but they run power steering and I don't.

I do think there's an interesting point Royce is raising here. I've had problems with death wobble after adding caster. Adding lots of caster to a live axle car is different to adding lots of caster to an IFS car with static camber.

I'm not arguing either way and don't want to get into a keyboard warrior argument over this issue, but arguing that adding caster to a live axle, radius arm car with no static camber is effective because you've found it's effective on an IFS car with static camber is a long bow to draw, no?

PS I think camber correction bushes are retarded.

You would say or you've set up a race car before? I never said my car didn't have negative static camber as well, but that was not the topic of discussion. Nor is my car and it's abilities or the fact it would probably give anything you've got a run for it's money around a circuit. My point was to convey that a little more positive castor is not a bad thing with my car just as one example. Not going to get into a keyboard warrior argument over race suspension that I've personally had experience with, in a car mind you that regularly gives the imports a hiding, albeit far from standard.

I would say you have nothing to offer this place and this thread is another example, now youve backpeddled

youve gone form no problem having too much, to a little bit more is a good thing

I just got offered a $50 donation to Rushos fund to ban you for a week, wonder what I would get for permanent?
