Hey,after i realized AFCO doesn't make taller "replacement" uppers for my metric..i installed the AFCO taller "lowers" on the front. This didn't really help anything did it? I thought this would help the roll center, but got to thinking about it...and realized..my tire stays the same...but the lower afco, just pushes the lower control arm farther down. I do have AFCO 1000# and 1200# springs..plus afco shocks....but do i need to try fitting the uppers in? I heard you can re-drill.....thanks!

It makes your spindle effectively taller, it lowers the front ride height, it allows you to run a better lower A arm angle for a given ride heieght and it iimproves upper A arm angle which helps your camber gain. I'd say it does a lot. Not sure of the effects on bumpsteer, but it has to affect it.

Maybe i should go ahead and fit the taller uppers on. I thought at the time, i was helping...by installing the lower afcos only.

so this isn't good to leave alone? We have a slightly banked 3/8 mile and a 1/2 banked dirt track.

25..a simple cheap method to check is to set the car at race condition with no front spring or shock. Clamp a 4 foot straight edge to the brake rotor, mark the floor at the end of the straight edge, now using a bottle jack, jack the lower controll arm up 2 inches. See how the end of the straight edge moved? ya got tow in or out?

fitting the longer lower ball joints should raise the roll centre slightly.
