Review: Excellent value and quality considering the cost and effort of just replacing OEM shocks. - Should have made this upgrade to my 96 NA Miata a while ago. My factory R package Bilsteins had 190k miles and were brutally stiff. For the price and still being adjustable and made in Japan, the Tein Flex Zs are hard to beat for the money. My old RX8 had them from a previous owner and I already liked them from experience. Goal was to have a more compliant, comfy but still firm street ride than the painfully stiff factory shocks and I’ve definitely accomplished that. I’m riding 8 out of 16 clicks front and rear like the manual said to start. Think I will go 4 clicks stiffer for my next test drive. My R package car was already 1” lower than normal factory. I went with the factory set non US measurement for ride height (B measurement, 40 mm front and 45 mm rear) which is higher than the US market measurement provided. Glad I didn’t lower it any because I still ended up about another 0.5” lower than where I was. Have not noticed bump steer yet. Install was easy as these were fully assembled and ride height was already set to the manual specs. I priced new, upgraded Bilstein shocks to replace my factory and the cost savings was small compared to these. And then you still had to disassemble your old shocks. I wouldn’t consider any coilover no name coilover kits cheaper than these and there are many more expensive options out there than these. The Tein Flex Z are the perfect balance of quality, adjustability, and price. I don’t care if this model is not rebuildable considering the replacement cost and the ones on my RX8 had lasted 150k miles with a lot of track use.
Review: Worth the money - Value option with top hats included. Do yourself a favor and remove the top control arm bolt (aka long bolt) in order to take out the fronts, made it so much easier. Enough adjustability for street use and much improved over stock.

### ⭐⭐⭐⭐⭐ Top quality coilovers
*by M***O on April 25, 2023*

This is the third set of these Tein Z coilovers I have installed in the last year on various cars.One was a 2008 NC Miata, one was on a 2016 WRX and the other on my 2004 Mazdaspeed Miata. The ride quality is excellent and the track performance is almost as good as a pure track competition setup. Best bang for the buck currently on the market. I installed all three sets at the recommended height setups and could not be happier. Bravo Tein!
