Spacing Crossmembers Effect on Steering

[PRIMRK]

if i was to mod the bonnet id let some of my american muscle roots show and stick a shaker scoop on it...

By the way I've read into this if i use larger roll center adjuster if i have to space it that will bring every thing back into line.

True or False?

now that I think about it your castor rods will be on slightly more of an angle, I seriously doubt this would have an effect though

[kaibeecee]

what motor are you putting in?

and moreso, what are you using to space it with?

spacing them should really be a last resort thing. depending on things, you might be able to get away with cutting a rib out of the bonnet and spacing the bonnet up a bit.

1uz i believe?

also think about the relationship of your front to rear roll centres. as while you may bring the front back to a standard platform, or near, that platform is now "out" compared to the rear pickup and pivot points

Here's some rough numbers.

Lower inner pivot at 140mm and lower outer at 140mm(~507mm guard to ground on AE71), the roll centre was at +24mm. Change lower inner to 100 and changes to -84mm. That's with 40mm RCA and XT130 LCA.

I had another spreadsheet which showed the effect of moving roll centres on total lateral load transfer distribution but I can't find that one. That'll tell you more in terms of what the car will behave like after spacing crossmember down. In theory, all you'll have to do is increase the front springs rate to increase to bring roll rate back up to what it was before with the downside being increased ride rate. Then you gots to deal with the steering stuffs, which is not a problem for you since you're doing cut steering arms. or did you buy T3?

i got t3
