Unfortunately NO!
Steeroids is a rear steering center take off rack and pinion, it allows you to place it about where the stock center link is and the center take off means it has a bracket in the center that tie rods bolt to.
The C4 corvette rack is a FRONT STEER END TAKE OFF rack and pinion, meaning it's placed IN FRONT of the steering axis, unlike the steeroids which like the stock box is rear steer. This means that the rack operates the other way around, if you were to place it behind the steering axis turning the steering wheel left would make the car steer to the right . This means the rack HAS to be placed in front of the steering axis. This is a major problem with the available room. Another even bigger problem is rack width. With a center take off rack you can modify the center rbacket for proper geometry (bumpsteer geometry that is), with an end take off rack you are stuck with the rack width, that is the tie rod pivot to pivot length. These have to align properly with the suspension and the placement is critical.
Because our C3s have a very narrow placement of the lower control arm cross shafts we can't run a wide rack. From cross shaft to cross shaft it's about 16" . If you place the rack higher you'll gain more room but there's a radiator there and the steering arm will become a clumsy piece of equipment. Hanging the rack lower means it has to be narrower than 16" and there's nothing on the market for that.
Here's the problem, the C4 rack is much too wide, it'll never fit properly and even if you cram it in there you'll have horrible bumpsteer or you'll have to stiffen up the suspension so much that the deflection from full bump to full droop is minimal and so is the angular effect of a misaligned steering setup.
The closest way is to use a 16ish inch rack and pinion from appleton, sweet, woodward, coleman or similar. This will allow you, with a lot of fabrication (and also, keep in mind the spindles and steering arms have to be flipped an adapters for proper ackerman angles have to be fabricated) to run a front steering end take off rack, the best kind of R&P you can get for a double a arm IFS (center take off is more sutied to mcpherson struts).
There's some drawbacks to rear steering, has to do with bushing deflection and steering input leading to oversteer rather than understeer but that's a whole different story
BTW, I have a front steering end take off setup....took some work but it's done:
ackerman adapters not yet installed
and it even works:
