Ebay Coilover Spring Swap

[Connor]

One thing I dont understand and cant quite work out in my head (and is probably a stupid question) but I dont get in my head how the raceland coilies need helpers and the gaz ones dont.

BUT

If I fit a 300lb 8" spring will it lower more than a 300lb 6" spring.

ie is the cars weight evened across the whole of the suspension travel meaning it would compress the 6" spring say 2" and also the 8" spring by 2" OR would it compress each spring say 5mm per inch meaning that it would actually drop further on an 8" spring than a 6".

Also how much further will a car drop on 275lb springs compared to 300lb springs?

Oh dont get me wrong, if I wound them down any more, they would need helpers, but I wound mine down to the point of just unseating
