I'm looking for some help setting up my 1971 Mini for autocross and would greatly appreciate any help.

 

The car is stripped of any unnecessary items (interior, mouldings, heaters, blowers, passenger seat, wiper motors etc.) Roll bar installed and entire car powder coated and baked. Subframes were removed, powder coated and replaced with all new hardware. Front and rear subframes have the harder racing cones, HiLos and adjustable GAZ shocks. The Cone setup is hardest in the front, slightly less in the rear. I have KAD swaybars front and rear. I have adjustable lower arms and tie rods front and KAD adjustable camber plates in the rear.

 

I would like to lower the car further than it is but, when I adjust the HiLo's to lower the car, they get to a point where the Cone starts to back out of the cup that holds it in place. Creating the potential to have the cone move out of the cup seems dangerous so I am wondering how I can lower the car further with the components that are in the car now?

 

One more item, I have the adjustable camber plates on the rear subframe and can only get 1 degree negative camber. Is there a trick to getting closer to 1.5-  2 degrees?

 

Thank you for your input!

You need to cut down both the Hilo and the adjuster bolt.

 

dont go too low or you can have ball joint issues.

As its autocross I am surprised you are lowering it so much

 

The rear camber brackets should give you more adjustment than that too

 

Is the radius arm touching the subframe at the top ?

 

If it is then it needs some grinding off

 

If not then the hole in the bracket needs to be filed higher, that will give you more negative camber. this can be done by hand or with a burr / cutter

 

Depending on how tight the end of the radius arm is they sometimes need jacking slightly to move the end up in the bracket

In the USA, 'Autocross' is what we call 'Autotest'. That is against-the-clock tests on tarmac around cones. Thus the idea of lowering the car. The speeds reached in USA on these Autocross tests can be quite high compared to UK Autotests.

Thanks for the response. Looking at the point where the bolt passes through the subframe on the inside, I can see where I can grind the hole to get the radius arm to move in the right direction.

Speeds to get fairly high. I've run my 911SC in third gear at some of the longer courses. UK Autotests are probably run on shorter courses. We rent the parking lots at major stadiums and race tracks for autocross events.
