Camaro rack & pinion

[coolwelder62]

Has anybody used the R&P from unisteer on their 67-69 camaro.Do you like it.And do you know what rack they use.

I've been pretty pleased with mine. The install had a few issues and now it looks like I need a new pump. The difference from the factory steering setup is EXCELLENT!!

Good luck!

I've noticed that alot of people are getting away from the rack and going back to the quick ratio box, Is there a reason for this? I need to make a decision myself.

coolwelder, check out the early 80's mustang II rack, its what wayne due uses for his c4 subframe, you made your own c4 subframe right?

If you are running a stock frame in the car, the newer steering boxes/rebuilt units from AGR, Flaming River, etc are a direct replacement, and offer terrific feel and performance. I haven't used the more recent rack units that are on the market, but I did use the Steeroids unit a ways back. Didn't really like it too much for the very short time I had it on the car. I went to an AGR box on my car when I did a motor swap, and am still running it. Awesome.

Downside for the boxes is that they are a bit heavier. So be it, I'll take simple, functional, and a bit heavier over complex, and uncertain any day.

If you are going to do a custom front frame, then there is little reason to consider anything other than a rack unit. Unfortunately, it's not as easy as just picking a Mustang unit out of the Summit Racing catalog and declaring victory, steering can be a fussy thing to get right. Lots of attention needs to be paid to packaging and insuring the unit is the correct width, and is located in the proper location.

as mark said, track width as well as lower control arm mounting points will push you where yo uneed to go as far as rack width, the deal is, you want the tie rod to swing as the same arc as the lower control arm, if it is not on the same arc/same length you will get bump steer(meaning the arc is different causing the tire to turn in or out thru susp travel)
some bump is ok, and most race guys like it to bump around .030 per inch of bump travel, meaning on a typical street car 3-4 inches of travel is all there is so something around .100 bump out is ideal,you want the .100 to move the tire out, this toe out condition allows the car to turn in right away, without the outside tire toeing out, the car will push as it cannot turn in as quickly as you want it to

I am starting a new sub frame built around the the stock camaro A arms & stock sway bar location. I am using 2 in round tube W/ frame rails narrowed so I can fit an 18X12.5 wheel on the front. and I want to run a rear steer rack. just wanted to know what rack unisteer used to play W/ fitment. If any body knows it would help. Thanks Scott.

Im confused...

So are you gonna flare the living hell out of those fenders and royally screw your scrub radius?

Or juist notch the hell out of the frame rails so that it will fit and be able to turn at least a little bit

So the question is how and why do you plan to do this? somehow i dont see the need for a 335 front tire but thats just me.


As for the unisteer rack ill let you know how it is tommarow! :thumbsup:

If that were true, then why would DSE, 21st century street machine, and Art Morrison (taking over on Wayne Due rack) be making sub frames with rack & pinions. The quick ratio box is an easy install, so that is the only possible reason. If you don't fall the Unisteer rack and pinion directions correctly. Some people like to skip steps, then I heard you will have problems with the unit. Check over on P-T.com and do a search on Unisteer, then you will understand.

Is Art Morrison gonna take over making Wayne Due like subframes?

No, our subframe will have nothing to do with Wayne Due. If that were the case, we would have just bought his jigs and started selling them already. Ours wont be available for about 8 weeks or so.

Can you share any differences or design principles behind your new sub? Appreciate any insights.

Steering geometry, rail design, torsional stiffness, and overall appearance are different.

It took me 3 weeks to get the steering geometry to what I feel is "road race quality". Not to say this is a race-only subframe, but should feel absolutely killer around sweeping corners. I had the California coastal highway in mind when designing it. It's meant to drive, period.

No I dont plan flaring the living hell out of the fenders.Nore do I plan screwing up my scrub radius.I am am doing this because it is america and I can. I am building a car 68 camaro W/18X11 wheels on the front now. The car has no flares or screwed scrub radius. Wheels 3in. out 9in. in back spacing. And no hacked up frame. My next camaro is going to be pretty much bad ass. Any body can buy some one elses front subframe bolt on a set of 8 or 9in. wheels and call it good. I like building stuff you cant buy. I want a camaro that will be differant than any thing you have see before. Every camaro I have built drives better than the last one.So these two should be no differant.I hope. The bottom line is I am nuts. Thanks Scott.
