Suspension for Sprites & Midgets
Created: January 28, 2011
Front suspension geometry can be altered to improve the cars road holding, further enhancing its cornering ability. Standard settings from the factory are 3/4° of positive camber, approximately 3° of Castor, and 1/8" toe in. Stock Spring rate is 271lbf/in.
SPAX frequently asked questions
Created: January 28, 2006
Frequently Asked Questions How do I adjust my rear telescopic dampers? There is a knob or a screwdriver adjustment at the bottom of each damper. If you turn the adjuster fully anticlockwise it will be on the lowest setting, then turn the adjuster clockwise - On our newer dampers there will be 28 points of adjustment and on our older dampers 14. You need to count the clicks, as once the maximum damping has been reached, the adjuster will keep turning. Always adjust both dampers an equal number of clicks.
Choosing a Sway Bar for your Mini Cooper or S
Created: December 02, 2004
The principle behind a sway bar is to achieve a ‘balance’ to the car front to rear such that when we turn at our chosen speed we can maintain control of the car. As a Mini Cooper will naturally understeer in order to get closer to a balance, we either have to decrease the understeer OR INCREASE oversteer.

Mini Suspension, Steering and Handling Data
Created: June 08, 2000
The data on this page relates to all Minis unless specified. Major changes to suspension and steering are limited to the introduction of a new steering rack and steering arms for Mk2-on models. Mk2 steering arms have two `ears' to aid in the use of ball joint splitters; this is how they may be differentiated from Mk1 steering arms.
Sway Bar Information and Theory
Created: January 30, 2000
A car has "neutral" steering when while turning in tight circle at moderate speed the car will complete the circle at approximately the same position across the diameter of the circle. A car has "understeer" when turning on the same tight circle at the same moderate speed the diameter of the circle is increased because of the front wheels "pushing" out!
Adjustable rear anti-roll bar kit, C-AJJ4008

Remove rear wheels and brake drums. Replace rear-most brake back plate holding bolt with the 3"x5/16" UNF cap head bolt provided. Slide on spacer tube, then
Progressive rear bump stop kit, C-AJJ3313
Created: January 29, 2000
This kit is suitable for all hydrolastic Mini’s. It can be fitted onto dry suspension cars to give improved handling characteristics during motor sport events, provided the rear radius arms are changed to accommodate them.
Fixed negative camber bottom arms, C-AJJ3364
Created: January 29, 2000
These are a direct replacement for the standard bottom arms and will add 1½° of negative camber to whatever the car has as standard - quoted by the manufacturers as being 1° positive, + 1°. If the car has 1° positive, fitting the negative camber arms will give ½° camber. Measuring what the car has with standard arms will help determine what camber setting will be achieved by using C-AJJ3364. Negative camber helps reduce under steer, therefore improving the cars cornering performance.
Front bump stop kit, C-AJJ4007
Created: January 29, 2000
Remove existing bump rubber completely. The smaller hole of the new bump rubber should be fitted over the retainer on the bracket, using hand soap or brake fluid on the rubber if necessary to ease the fitting.
Mini coil over conversion kit, CK17
Created: January 29, 2000
This kit has been designed specifically for road use with the view to limited tarmac competition events. If used for “off-road” purposes, strengthening modifications will need to be made, as failure may be a possibility. All wheels and tire combinations fitted to the vehicle should be inspected as it is essential that there is enough clearance between the wheel . tire and suspension units. Very minor adjustments using wheel spacers may be required otherwise.
Heavy duty adjustable tie-rods
Created: January 29, 2000
These rods have been produced to improve car stability when cornering and braking, and facilitate easy adjustment of castor angle. Manufactured from a high grade material in a much bigger diameter, they are less susceptible to bending than the standard items. The standard castor angle is 3° + ½°. This will change when the car is raised or lowered, and when adjustable or negative camber bottom arms are used (these tend to increase castor).
