88 rear suspension geometry

[rkovacs]

I have heard the 88 rear suspension geometry is different than any other years. What makes it different and will that change if I switch out the drum brakes to disk brakes from a newer car?

That's a really good question. I've seen it asked a number of times, and there hasn't been a really good answer.

The 88s do have different lower control arms on the rear; they are either the same as or the same type as that used on the Integra Type R. The shock mounts are different than the later years of CRX. I don't think that accounts for the "passive rear steer" (or rather, dynamic toe angle changes) so there may be other differences as well. Possibly the exact mounting point, or the compensator arm, are different.

The key difference is in the body-side mounting point of the compensator (toe) arm, at the forward end of the rear trailing arm. It creates an aggressive toe curve that causes that "passive" rear steering that everyone talks about. Changing the trailing arms or swapping the brakes can do nothing to alter that geometry.

Perfect, that is exactly what I was looking for. I didn't want to loose that if I changed over to disk brakes.

Ahh, so its the forward trailing arm mounting point? Thanks for the info.

Are you familiar with just how much dynamic toe it creates? I think i saw someone on honda tech post up he had -.015 toe out under compression of 2 inches or so.... i'll have to find the thread. He had an EF civic and i believe it was a 91.
