I've got a 5.0 with an awful suspension setup at the moment, and got an opportunity to pick up almost brand new Tein Street Advance coilovers for $400.
Considering I'm on a budget, it seems like a good option, but just wondering if anyone has any experience with these, particularly on a v8miata? He says spring rate on them is 7kg in front 6kg in the rear, and from a quick google search that looks like ~400lbs/in and ~340lbs/in. Thoughts?

 

i buy it by 550 usd

 

Hi,

The front springs are a little soft. I have 525lb in mine and feel the front is slightly under sprung, a 575lb front spring would be ideal. The rear setup at 340 lbs is on target and good. Tein are a decent product.

You can always change the springs before you install them, or change them later if cash is tight.
