Dutton Kit Cars and their owners

MY car used to have the geometry as follows...

Front;

Castor N/S  1 degree 55 minutes

          O/S  5 degrees

Camber N/S -ve 2 degrees 02 minutes

            O/S -ve 1 degree 19 minutes

Rear;

had a slight thrust (steering) to N/S of 0 degrees 28 minutes (had worn bushes, so i thought that was the problem)

Today i have just had it checked on the same machine and got the following......

Front;

castor N/S 6 degrees

          O/S 6 degrees 40 minutes

Camber N/S -ve 1 degree 20 minutes

            O/S -ve 1 degree 27 minutes

Rear...almost exactly the same as last year at 0 degrees 32 minutes to N/S.

This will be easy to adjust out with two new trailing arms (adjustable)

Considering the front end was lined up more or less by eye and some rudimentary measuring because it was made to be adjustable, i am made up that it has come out almost exactly where i wanted it. I was aiming for a castor of 5 degrees +/- 3 degrees and a camber of -1 degree. the results above are so close that i will leave them as they are. even the tracking came in at.... toe in 1.25mm! Again done by eye...i am made up that it has come out so well.

When you consider that every single suspension point has been modified moved and renewed it is absolutely brilliant that i was able to get it right first time.

The rear axle thrust is noticeable when cornering hard and fast making the car slightly more willing to turn to the N/S, it wasn't noticeable before! (as you would expect if you think about it) but the car handles so much better now. it feels like it is glued to the road.

" Rear...almost exactly the same as last year at 0 degrees 32 minutes to N/S "  that's probably down to the chassis being longer one side than the other, it'll feel at hone with those SD1's as they're the same :-)

You wont want more than 1 degree neg camber on the front. Bet it selfcentres really good now :-) can't remember off the top of my head what 1.25mm toe is as an angle 10-12 minutes total should be all you need on the front with decent grippy tyres.

Main problem with the Escort rear axle is you cant adjust for camber and toe which is where a light car really needs it!
