1) I have been told I can't use the power steering mx5 rack, so i have been looking at a mk1 escort 2.9 quick rack would this be okay?.
2) What would be best for wishbones? I see you are not going to use wishbones as per the Saturn plans, Robo has posted a link to some wishbones will these be what you are going to use?.

Thank you in advance for any information you can give me.

Regards Mick.
Hi Mick,
Firstly thanks for your kind words.
I bought a 2.9 Escort steering rack from Rally Design for my build with the ally clamps. Be carefull not to get your steering rack extensions made as per book as the MX5 versions are shorter.

I originally made Saturn type wishbones and over time have changed all of them except the rear lowers.
The front lowers I've removed the front adjusters as "Toe in and out" can be altered by the steering rack extensions. I've kept the pivot points the same but made a different outboard end to hide the bottom ball joint and lower the tube to overcome the steering rack extension fouling the tube on full lock as some people have reported.
Skov overcame this problem by fitting plastic tube in the rack to reduce lock to lock.

The front uppers have changed to accomadate inboard rose joints to allow me to adjust caster in case self centreing is a problem (see Algas thread on this) and it can help if you use standard lowers to overcome the steering rack extension fouling the tube also. Where the top ball joint fits I've fitted a camber adjuster to change camber without removing any parts on the car when setting up.

The rear upper I have moved the shock mount to above the upright and made the camber adjustable on the car without removing any parts.

Everything is detailed in my photobucket so any questions just ask.

All my alterations are drawn up in Autocad along with the chassis in 3D which I should be able to pull up any measurements if required.
