In other questions, are there aftermarket, manual racks for the c5/c6?
On the grand am power rack, I just crossed the hydralic lines and used it as manual. It may work on a c5.


Edit: quick search shows photo of c5 rack with a “jumper” hose on the pump connections.

Can you feel the valve in the rack when you're driving?

On the grand am rack, no issues. I crossed the lines, I’ll see if I can find an old photo.

The only thing I really should do is make new bump steer blocks that give me a tighter turning radius.

The guy that posted the c5 fix was over at CF.

Looping the line (in-out) works.

I read the discussion and it doesn't seem like anyone said "I tried it and it worked"

the thing I'm curious about. If you pull the power steering pump off a C3, the valve in the steering makes for a lot of sloop in the steering. Rack and pinion use the same kind of system - but it looks like a lot less play, so it may be nothing - that said, I'd hate to put this all together and find out that, while it does a nice job centering, it does a terrible job and being neutral on the road.

Is there a manual steering option for a C5? I wouldn't think so.

Some people are running the Grand Am rack on C3's without a pump and no issues. It probably wouldn't be great for parking lot maneuvering but you probably won't be doing that.

so the next step will either be gold or goat.edited I'm going to put Camaro rotors and Camaro Brembo brakes (basically rely on the design of GM).... will it work?edited dunno

I know I can make it work and I know that I'll have to build adapter brackets.... but here's the deal - Detroit Speed suspension is 18,000-23,000 and I may have 2k in this suspension with the new coilovers..... that's front/rear price.... wish me luck

as for the rack - I'm going with a stock C5. There is a drag-race manual rack available for about $500 but it states no street use - which could be an anti-lawyer device or could be it's not designed for high-lateral-g loads.... I'd rather not bet when it comes to that. Thus either I'll make the C5 steering manual (with the bypass line) or I may put a pump on and have hydraboost brakes as well. That said, I may make the steering true manual by converting the stock, C5 rack

i like the C5 rack on my C5 and i liked the steeroids rack on the C3 (i think that was the grandam rack), i did have to play with the shims in the pump on the C3 to get the pressure right.


I think it would be hard to argue against the c5 rack as a good choice, can you use all the speed sensitivity steering stuff as well that the c5 has?? i guess the power steering pump pressure is reduced as the speed goes up.
