Hi Areg
I was told by my dealer that our regulators wouldnt like the comfort kit.
I decided to go another route and bought the adjustable shocks for the front and lowered the car sufficiently to get the steering arms near horizontal. This makes the steering much better .
Only down side is that you have just 4 inch of clearance at the front. No big issues really to date unless on dirt road!
Food for thought
I'll admit that getting the lower stance will help, but the bumpsteer is a situation of an out of alignment with the a-arms, not the ground.
If designed correctly, you "could" have a setup with all a-arms sloping upward and the tie rod sloping upward as well. As long as the length of the tie rod is equal to the theoretical distance of the pivot point of both a-arms and the centerline of the upper/lower ball joints as its own elevation, all is good.
I know that in the past lowering gets the bumpsteer better, but raising the tie rod upward at the outboard end is the best way to do this.
I don't think a spacer is the correct way to do this and MMC has since moved the steering arm up on the spindle to the proper point.
Doesn't the comfort kit have another steering arm that bolts in under the top ball joint and then you mount the tie rod end under the top NEW steering arm and use the spacer under the end to make up the difference? Again, not the best because the upper arm is not welded to the spindle, but better than just the spacer and the tie rod end bolted to the top of it.
I found that with some bump steer on my hot rod with a solid front axle, if I didn't hold on tightly to the steering wheel that the steering wheel would move within my hands and not force the tires to move around out front.
I hope all is a bit better for you now, enjoy your ride.
