I've kept the car stock for the last two years and am now looking to upgrade the wheels, suspension and brakes to 952 spec, (at the very least!). With regard to the the rear axle upgrade, what is the best way of making up the nescessary 23mm difference?
Having removed the trailing arms of an 89 model and discovered how difficult it was to persuade the aluminium to part from the steel spring plates. Is it possible to retrofit the 89 5 bolt wheel carrier & hub to my original , 86 trailing arms?
