Long term, I wouldn't build an aluminium tube chassis as it will be prone to fractures. The only design I would consider using aluminium is a monocoque design like the Robin hood.
Just take a look at Elise/Renault spyder etc.

i was looking at building a single seater like yours but all folded out of sheet with the seat built in to the chassis. but i cant find any drawing for the front susenpsion or anything to go on. so iam just thinking of ideas what to do.

Have a look in my archive for some suspension drawings.
Your will need to make some paper templates or use solidworks like I have here.
Work out your hub pivot points. In the first picture you will see that my hub includes the knigpin inclination angle.
Then from the width of the car, work out approx wishbone lengths and inboard pivot points and angles. Just move them around until it works as in the two following pictures.
You will want some camber gain and loss as indicated by the line on the left. How much is dependant on your wishbone/hub travel.
My setup will have air adjustable shocks that will give me from 0-6" ride height with normal running of 3" high.

If you want to save the hassle of building a car, you could buy mine!

Try Staniforths "Race & Rally Car Source Book" this covers the building of a single seater in the way that you want.

Also try here for a few other pointers
