Anyone make Linear lowering springs?

SS_Firehawk · 01-30-2015, 05:40 AM

As the title says, I'm looking for linear lowering springs for my car. My opinion is that I think the Nismo handles great out of the box, but I don't like the boat look the stock suspension has. I'm apprehensive about adding progressive springs as they compromise what I don't want to change; handling and predictability. I'm only looking for a minor drop. An inch at most up front, 1/2" in the back.

If there is no out of the box option, what options do I have outside of coils? Don't even recommend cutting...

sounds like what you want you are stuck getting coils

there is a reason why your car has the boat look though...for front clearance.

id leave it alone if you like the handling.

Think your only option is going to be coil-overs.

I think I found something. This a Japanese company that's relatively new to the US. The springs might do exactly what I want. What do you guys think? They're listing for around $180 on RHD Japan. Not sure what else I'd have to pay going that route.

Downgrade. Factory nismo spring rates are 8.6kg/mm front and 9.1kg/mm rear what we need is for swift to make a linear vers of their lowering springs with everything else thevsame. Id buy that.

hell i just got the reg ones and well see how they do on track this weekend when my wife reports back.

Don't waste your time with RSR.

there is not a lot of spring preload in the rear or our cars at full droop, put too much shorter of a spring in there and it might fall out or become cockeyed if you get a wheel off the ground lol. I think thats one of the reasons they seem to make lowering springs dual rate/progressive. They let part of the spring compress more at ride height so you can put a spring in there thats shorter at ride height but still has the ability to expand to oem height.
