ERP bump steer on the street?, Will those hiem joints last? Options

[blabla914]

Does anyone here have experience using an ERP bump steer kit on the street? I'm concerned about wear. I drive my car quite a bit (5-10k/year) on the street and I'm worried about them wearing out quickly since they aren't sealed. Anybody have experience with this?

Thanks for the replies guys,

My understanding, and I've looked at it a bit, raised spindles will increase usable suspension travel and increase camber gain, but the steering arm will still be up too high. It's the upward slope of the tie rods that creates bump steer problems. The closer you can get the tie rods to level, the less bump steer will you have.

I'm not certain I need the bump steer kit. I just want to know if the ERP kit is even an option, which it sounds like it isn't. I'm going to pull the torsion bar and run the suspension up and down and see what the bump steer actually is. I think I have more than I'd like. If I run less than 1/16" toe in on the front the car becomes quite unstable over the bumps. My thought is as the front wheels are going up in bump I am getting toe out. If I run a bit more toe in the effect is minimized, but less toe in makes a big difference in the middle of the corner for me.

The car is low. I've got 5 1/4" from the rocker seam to the ground at the jack point. I am running 205-50-15's on 7" wheels with stock struts and the rack spacers in place. If the ERP's are not an option I may just raise the car up a bit.

it is almost protocol, that when you raise spindles, you heat and bend the pitman arm down.....
