As for ride quality when cutting springs, it takes me back to the mini truck days, talk about feeling every freakin pebble on the road!

Cut springs in a '78 TransAm with a 454 LS7 big block. :driving:

Seems like you have a general misunderstanding on why lowering springs are stiffer.

What is the ultimate reason why people go this route? Are we talking washer mod level here?

Lack of funds and lack of parts. I did try the washer mod... for about ten minutes..

When I did mine. There wasn't any thing out there. We're talking 1980.

the op says he wants to do it because every spring on the market goes too low for his taste...

The nismo kit is still easily available. It offers minimal lowering and rate increase and comes with dampers for under 1k.


Nothing seems to make people on the internet angry like a good old fashioned spring cutting thread. Mad props, op.

I can get the ends flattened without issue.

What companies have selectable rate springs? This is the first I'm hearing of it in anything other than a coil over.

SPL carries Swift springs. If you are not using a true coil overs in the rear. You have to use the SPL arm for springs.

You can actually get adapters to be able to run the common 2.5 or 2.25" ID springs with the factory arms. As I went the SPL route I don't know much about them other than that they do exist.

Interesting, I didn't know the Swift's could be had in varying rates. Gonna give SPL a ring. Thanks Rusty!

I just used that as an example. There is others out there. But SPL came to mind. I'm in Vegas using my phone. So my research is limited.

If you heat and bend then ends it would affect the heat treatment.
