I think the GREEN/WHITE/GREEN rear springs from bhakola are just 'reinforced' springs instead of the original BMW Turbo springs. It would be nice to know which springs were fitted when the car left the factory.

 

I'm still working on the Codex, but calculated the rear Green / White / Green to be 126 Lb. in. whereas my rear OE White is 165 Lb. in.

 

The front Hakola Turbo Green / Blue calculates to 119 Lb. in. whereas the stock 2002 Green / Blue / Green is 97 Lb. in.

 

Tomorrow I will be in the shop and can look for my front springs........

Thank you for that information.

 

To be complete can you measure the Outside diameter and either the inside diameter or the wire thickness and the free length?

 

That would be most helpful.

 

Thanks,

Your White / Blue Front Springs are 124 Lb. in. vs. my White / Blue at 98.56 Lb. in vs. Green / Blue at 119 Lb. in.

 

Your  Red (only) Rear Springs are 160 Lb.  in. vs. White (only) at 165 Lb. in. vs. Red / White / White at 133 Lb. in. vs. Green / White at 142. Lb. in.

 

I haven't plugged them into my other suspension dynamics spreadsheets to see the net effects of the differences.....
