I've searched but never found anything on this topic.. I have a 96 Civic HX Coupe, manual trans..

I'm replacing the suspension in my 96 Civic coupe, manual trans. There are two OEM replacements for the front one for automatics and one for manual models. The rears are the same between auto/manual. The spec difference is 957lbs per spring in the front for manual models, and 1038 load lbs for the automatic.

Now here's my question, I am a tall guy and weigh 300lbs, yeah I know I'm big, but with that weight I've had to have alignments with me in the car because I cause the stock suspension to sway to the left. They do the alignment with me in the car so I can drive straight without the steering wheel to the right.

I was doing some calculations for the 96 coupe and wondering if I should just use the automatic model springs on my manual trans civic because of my weight. That way I would have springs that would support me better.

Is this correct thinking? I did calculations based on the weight of the civic (2313lbs), distribution of weight (62%), then dividing that by two to get the individual corner weights. With that I then subtract what the replacement spring can support plus my weight. And all the calculations show with me in the car I'm beyond what the manual trans spring could support in the front! With the automatic model spring I'm fine.

So let me know if I am correct in my thinking, thanks!!
