Bumpsteer Question Does anyone know if the 4th gens suffer from bumpsteer issues?
My car has been lowered and I've never felt an issue, but in looking at the geometry it doesn't look optimal.
I'm going to be making new lower control arms with a fixed camber bushing (adjustments will be made with the upper control arm) and in the process I can move the camber bushing mount further in, out, up or down. So now is the perfect time to position it in the correct location to eliminate any potential bumpsteer.
Here's how things look stock:
From what I understand, you want the steering control arm pivot to be inline with the upper and lower control arm pivot points.
So something like this:
Am I over simplifiing things?

Another site says that the steering link angle should intersect with the instant center. Like so:
So maybe I should leave the LCA arm mount where it is?
If there are any gurus on the subject here, please chime in. Thanks.

I'm no suspension guru, but I will comment on the fact that I do I have horrible bump steer. I bought a Spohn bump steer kit a while back but I haven't installed it yet. I am waiting to install new shocks (next week or two) so I don't have to spend $300-$400 on an alignment twice. Hopefully they'll fix the issue, but I cannot comment on results and/or geometry!
