let me know what you got..

 

I have a set of Intrax lowering springs sitting in the garage. I'd sell them for $90 shipped.

They were on the car when I bought it, I switched them out for a Tein coil-over kit for the adjustability. I only drove them for a couple weeks but from memory they were low, stiff, and gave the car a good stance. Fits NA 90-97.


A quick Google search turned up the following details. There are some reviews on Miata.net as well.

The springs are manufactured in Germany or Belgium.

"INTRAX Springs are produced in Europe to the highest standards. All springs are cold wound on WAFIOS CNC coilers, from the finest grade of Chrome Silicone Wire. They are then Heat Treated, Shot Peened and Blocked to insure fatigue resistance. Finally they are Epoxy Powder coated to provide a long lasting and durable protective finish. Each of these steps is carefully monitored to guarantee you the finest product you can purchase. That's why inTrax backs all of their Springs with a Limited Lifetime Warranty. You can use inTrax springs with stock or performance shocks."
