Suspension Upgrade Time - Installing QA1 Proma Star Double Adjustable Coilover + Progress Swaybars

Short Version:

Overall a solid product with great potential, when configured right they work pretty darn good.

Getting these setup right however is no easy task. These are unfortunately plagued by incorrect spring rates, sparse install and configuration notes, and minimal community adaptation to fill in the blanks. A few design choices are also difficult to work with and can cause issues.

Current Parts / Specs

This page will hopefully continue to serve as a place where I can keep track of the current modifcations done to the Miata. Some modifications and work were performed to the vehicle prior to my ownership, and I will update to include that information as soon as I discover them.

I purchased some Hood Louvers for my 1999 C5 Corvette after watching a variety of youtube videos all claiming it helped with cooling. My goal first and foremost with the Corvette was to keep it cool. As an added bonus, the louvers looked REALLY friggen good on the Corvette, so I was all about installing them.
