Centre fix steering rack?
Anyone know of any centre fix steering racks? Having a central driving position it seemed a bit daft going for an offset rack!
Cheers

I'm guessing it's a centre fed rack you're after. Try Geoff Berrisford or any of the other Autograss builders. If you are having
trouble U2U me and I'll put you in touch with a guy near me who does them.

I actually stumbled upon Titan shortly after posting, discounted as there website suggested a remortgage would be necessary, but that's not too
bad! Also been suggested Jack Knight on another forum so will contact them both tomorrow.

The advantages of your own rack are:
1.) You can chose the pivot points so they line up with your wishbone pivots and prevent bump steer. (My rack is inline with the top wishbone and
pivots match the inboard bolt centres).
2.) You can chose your own ratio (mine is 1 turn lock to lock)

2 very good points - the first... well I was looking for a rack before trying to find someone to help with the suspension, for precisely that reason.
The other way round would obviously be preferable 
the second. Flick me 1 turn?!?!?!

Blimey! I thought my 2.4 turn rack was too quick!  Thats going to be as twitchy as hell isn't it?

Only twitchy if your castor is wrong.
If you put the right amount of castor in your set up, then driving with a one turn rack means that driving out of corners is a breeze.
You don't have to take your hands off the wheel unless you need to change gear, which is the correct way to drive, plus no crossed arms
either.
With good castor the car also drives straight and with the turn ratio, you only have to think about changing lanes on a motorway and it is done!
The F1-2 has a 1 1/4 turn and has brilliant feedback through the steering.
The only problem is if you try manouvering in a tight space without the car moving, but you soon get used to this and start turning while you are
still rolling.

are you going to be putting the car through SVA?
with the central driving position, i guess the engine's going in the back, plenty of room up front for the steering collumn, if you used an
offset one, your column could have 2 UJs and a high angle, meaning you don't need to worry too much about the collapsable shaft, and won't
need to pay out for a custom one although it would look at bid if you can see it.
every cloud?
just a thought

The reason I have gone for a centre rack is for the steering safety offset as the MotaLeira will be RHD
On the F1-2 I had a centre rack because of the single centre seat, but you can just see two UJ's which give angle changes and was acceptable for
sva.

funny you should mention that 
yes it's going to be SVA'd eventually, and the 2 UJ's will be used, partly for the collapsible column point of view, but also
because my feet will be sitting pretty much on the axle line of the front wheels, so it'll be going out then down, if you see what I mean.

As everybody has gone down the Titan+Jack Knight route, go back and read Rich Quinn's post!!!!!!!
Geoff Berrisford does these for £150 which are just as good, just slightly heavier:
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

I've been meaning to come back and ask Rich about that - I haven't turned up contact details for GB yet - do you have them to hand?

don't see why not, but it would be at your own risk obviously!!!
They stand a huge beating on track without failing, but obviously never complete that many miles in total
Certainly very well made, as is everything from berrisford, sorry to say his stuff puts "kitcar" stuff to shame from many (not all! )
suppliers.
He does ally hubs for them and all manner of other bits and bobs, iirc a complete front hub set with uprights, ally hubs, bearings and adapted bike
brake discs is around £250.

not for me, but others on here. £44 each seems a great price.
I've already got mine sorted, mine are from a bedford midi
