Upgrading to SN95 steering rack

[gkomo]

This is all crazy talk. I just got a rack from O'Reilly's for like $150 with core exchange. It's a damn steering rack, why would you pay more.

My 99+ GT reman rack from RockAuto was like only $108.99 with the core refund.

I guess the expensive part of the conversion was the solid hybrid steering shaft but that’s what probably made the most difference.

The torsion bar in the SN95 rack is stiffer so it has less assist when turning and to me when the thorns started the assist is not as high which I prefer. More detail here:

Yeah, no kidding. $150 for the steering rack, $390 for the Borgeson steering shaft, and $150 for the Detroit Drift firewall bearing. The rack was the cheap part.

I assume I should be using the offset rack bushings? Car will be lowered.

 

[gkomo]

I didn’t. Just ‘upgraded’ to poly bushings. No issues that I’m aware of.

Depends on how far you are going to lower it. Offset bushings can keep you from needing a bumpsteer kit. I have both on my car but I’m an idiot and lowered it a bit.

Your stance looks perfect, that's how I want my vert to sit. I guess I wait and see?

You can see mine is also very low (in the front) with some garbage ass H&R race springs. My front tires basically tuck up inside the fenders. I plan on changing all that with coilovers but for now I don’t believe I am experiencing bumpsteer. However I’m no race car driver so maybe I just don’t know what I’m looking for.

Long story is I think you can get away without offset rack bushings but if you need them just swap them in.

I can just about guarantee you are experiencing bumpsteer but like you said you may not really notice it. You just need to make sure the tie rods are parallel with the control arms when the car is on the ground and the suspension fully loaded. Is this the correct way to set the bumpsteer? No but for a street cat it’s good enough. Setting one up with the gauges is a huge pain and anytime you make a change you have to go through that whole process again. I’ve done it on a buddy’s American Iron car a couple times and it was not fun.
