Hiya Guys,
Sorry for the response time....Im trying to build a couple of cars, and a new engine room at the moment...and this seems to be taking all my time at the moment!!
Please don't be concerned about my reputation, I am a one man band....but I put in a lot of hours, and everything is well underway!
The guys on the Rx7 forum have all been happy with the product...and I'm sure you will all be happy too! The company that are making the racks also make the racks for Formula Ford, Catherham, Lotus, McLaren to mention but a few. I witnessed the MP4-12C wishbones being made....all from billet
I have had 3 people contact me offering deposits now...but we do need to get to 10 units before I can offer the full group buy option. I have now sold almost 30 units for the Rx7, and not one complaint!!!
So to answer a few questions and the odd concern.
Why should you go with one of these?I have already said about the faster speed. This will not give you any less travel. The travel is identical to the standard rack. Any less than 2.4 and it will become "too skittish"
We can offer 2 options on the travel:The first is a standard rack.The second, aimed towards the drift community, is an extended travel rack offering a further 38mm of travel.
Why go for this over a modified standard rack?The standard rack is designed for using fluid. There are certain stresses that will occur without the fluid, and so putting the internals at risk of failure. The gears and pinions are designed to be smoother than standard operation. Yes it is slightly more expensive than the modified solution. But once you have seen how beautifully made this is you will agree with the other owners that it is worth every penny!
Can it be power assisted?The rack cant be power assisted, but the column can. We are looking at a couple of systems that offer EPS and adapting them to work with our rack. The advantage of this will be that you can control the level of assistance as well as being able to regulate it through speed.
The feedback you get from these racks is remarkable. You will find yourself hitting apexes cleaner and more precisely. And so on the track it is an absolute must. For the road...yes it is slightly heavier, but I think you will find this isn't too much of a hindrance, and you will certainly notice the advantages when on your favourite section of road
Some quotes from the Rx7 forum
*********************************************I'd like to thank Jon at AtomicRex for making this. First, Jon, the unit is beautifully made, and while I won't be driving the car until Saturday, I have turned the steering wheel both without any load and with the motor in it and can tell you that the precision feel of the rack is phenomenal. Its so much smoother turning than any version of the steering rack that I have felt, both powered and manual conversions, whether looped or true manual conversions like Maval. Its a completely different feel. Sure there's a little effort required, but its just so smooth and precise and virtually no play at all. And, because there's 2.4 turns lock-to-lock, its a LOT faster turning.
I will report on the steering feel and effort more over the weekend. I am wondering whether the solid and beautifully machined mounts (third variation, Jon?) will transmit too much road feel for street use. We'll have to see. But, I am sure that its the ultimate track set-up regardless. And, if there is too much feel for me, I'm certain some poly material could be inserted to dampen that anyway.
Summary is that so far this is one of the very best new things to come out that makes a real difference in our cars. The stock steering was one of the real weaknesses of the car that was reported in the press from day one and that we all have noticed. The stock assisted steering is a little dead and slow and has way less feel than you'd want in a car like this and that's why so many people convert to some form of manual, whether looped line or Maval. I had the looped line on my old car and have tried to order Quaife's "Quick Steer Gears", but they never actually made them. This unit provides the best of all worlds with both an incredibly well-made pure manual unit where the precision of the billet aluminum machined parts, especially the rack and gears themselves, are like a Swiss watch and turn much smoother than any conversion of the stock set-up, AND its also got the quicker turn ratio.
Let me comment on price, which is about $1000 unless we organize another group buy. I hear some guys saying that's a lot compared to a simple and free looped line conversion or even the Maval conversion at about $300-400. People readily spend $1500-4000+ for coilovers and $2500-6000 for big brake kits and $2000-4000 for wheels and tires and on and on. This is less money than any of those things and will give you a direct improvement you can feel and that will make way more of a difference to your driving experience than almost anything else you can do to your car. I'd invite anyone in my area over for a drive and will give drives at the Carlisi meet this August to as many people as I can. This is really a great change to the car. I can't say enough.
jkstill... I haven't done any autox with the rack. However, while, as you said, the Maval is better than the looped line, neither compares with the AtomicRex rack. It is better than a Porsche manual rack or any other production manual rack I think because of how well machined it is. The effort might be one half of what it is with the Maval rack and one fourth the effort of a looped line converted rack. There is very little effort required.
If you come to the Carlisi event, you can try mine and see.

Damien, et al.,
you're going to LOVE the feedback of this rack on the track.
CMP (Carolina Motorsports Park) is a fairly twisty track, and the feedback this rack provides is sublime.
