Just wondering how the non Sydney fellas get the springs custom wound to suit the car? I ask this as i'm having abit of difficulty in getting springs matched to specific heights...
Originally i wanted a pair of 3.6kg/mm (200lb) linear rate rear springs to suit the rear of an AE86 running approx 2.5" inches lower than stock. When i got the package i was surprised to find that the coil was 230mm free height. I have not fitted this but i'm expecting this to have the car sitting with most of the rear wheel inside the guard. - Might not even be able to remove the car jack. A low 6kg setup has 240mm free height. Running the rear 40mm lower than simons drift setup might not be a good way to start .. hence didnt bother fitting em.
After the crap feeling of spending money and to not have the rite springs i tried to contract the manufacturer to get me a spring to match the ride height of a 240mm free height 6kg spring but wound in 4kg. I was then told that this would be hard they would have to have a sample spring to make calculations from. I write this with no negative assertions made to any spring manufacturer.
As bad as it sounds .. i came up 2.5" lower as i'm running some lovells coils which are *supposed to be* 2.5" lower and also having seen mr20v old car in pics with 2.5" lower 6kg springs. I guess this method of highly scientific ride height evaluation does not work all the time.
So the question is.. how does one get custom springs made (with a good degree of precision) if they are not in NSW ?
Or does anyone know how to get a liner rate 4kg spring made with similar ride height to match a 6kg 240mm free height spring.
