I'm not mega interested in running more than 1.5 degrees static camber on my car. It's mostly road, but ideally I'd like it to not completely kill its tyres on track. It's going to be about 45mm lower than standard with very slight toe in. Any idea what would be decent castor setting to achieve some sort of dynamic camber on these macp struts? Will it need roll-centre adjustment too?

Spring rates won't be mega stiff, 21s rear about 280 front depending on what engine I use.

Cheers

Well my rally car does mainly tarmac roads. So to account for the camber aided from the drop to the roadside, I run no more than 1.5 degrees camber. Anything between 1 and 1.5 really is what I go. But then il run between 4 to 7 degrees of castor. Although when you get towards 7 you need to cut the wings down and a good chunk off the front bumper as the wheels are a lot further forward....

It's always a trade off unfortunately Adam, I'd say -1.5 as a maximum for road use though, you'll still scrub the inside off first at that mind.
As far as castor goes, just get as much as possible! As devere says you're fairly limited anyway, it's all useful though.
What engine are you thinking of using? 280lb springs is fairly stiff for 21mm bars. Or are you using a mammoth rear arb too?

Edit: as Adam asks, how are you getting the castor devere?

Thanks guys - I will be looking into this further in a couple of months when everything else is sorted out. I have a lot to sort out before I have a chance to concentrate on this side of the car.
