there is far more to correcting bump steer than raising the rack a bit. Do you know how much your springs lowered the car exactly? Did you measure stock, then measure with the springs installed after settling?
Did you take into account the original angle of the tie rod? Angle after spring install?
Do you even experience bump steer now?
Do you understand why the rack spacers correct the problem?

Overbooster made them and did all the measurements. As far as why they correct the problem I may be wrong but I believe like you said above to keep the same angle on the tie rods and not create added stress on them since they were designed to be at a certain angle. Do I know how much my car is lowered no and now that you mention it I should have checked. I put my trust in Alex though. The bushings I have versuses the stock ones are solid kind of the same concept with swapping the motor or tranny mounts. Now there is no movement in the rack when turning. To be honest though I'd trust these more than the rack spacers sold buy some of the vendors since the bushing has a flange to it that acts as a spacer. I don't know what bump steer is so you'd have to explain it to me. Like I said I put my trust in Alex to pick up where my lack of knowledge is and there is still a lot about our cars that I'm trying to learn.

Also, there are no bushings there, the steering rack bolts directly to the subframe. No movement, no slop.
So far he seems like a cool guy, but I have not seen anything he has posted to make me think he knows as much about suspension tuning as he should to be making rack spacers himself.
Then again, what do i know?

I understand where you're coming from but there is actually a bushing that's pressed in the rack itself where the 2 bolts go through to mount it to the frame. Those bushings have a metal sleeve that's surrounded by rubber which is where there's that possibility of movement. He's a sharp kid and he works/builds porsche race cars which is the only reason why I let him put them on my car. I know you're not trying to be a dick you're just trying to help. Trust me if I do something stupid I like to know about it haha

I'm not trying to be harsh, i just see to many cars fucked up by shadetree mechanics, and i hate to see the spread of so called "knowledgeable" people throwing parts into a car without understanding the engineering behind it.
The rack spacers distributed by OTTP are built by a man who does nothing but race and build race cars for a living. the rack spacers he designed were tested and proved with hundreds of miles on the race track, as well as street time. He also custom tailors the thickness depending on how much your car has been lowered. There is math behind this, not a theory.
If Overbooster wants to post his calculations, by all means, RAD. If not, be careful, and crawl under there often to inspect your steering rack and related components.

I understand. I appreciate the fact that instead of talking all kinds of **** like most the people on this site you're trying to help out. Like I said if I didn't feel like I could trust his work they would not be on my car.

hahaha i like the way will works.
lol. btw im not one to bash (anymore) but overbooster ported everything possible on his ss/tc and now doesnt run that well.
Im just careful with what i see and what I hear (most of the time).
Will you need that car rolling dude!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Just because he works with Porsches doesn't mean he knows what he's doing. Any monkey can turn a wrench.
If that's true, its a classic example of understanding the theory, but not the science behind it. Porting is beneficial, but bigger isn't always better.

Will u make a good point and i was either gonna get the rack spacers from ottp whenever i ordered my springs as i read without them the geometry is off when lowered which makes plenty of sense
but i got interested in the ones mofofernando has with his sportlines

Buy from OTTP.
