Has anybody heard of the TEIN FLEX Z Coilovers for the Mazda Mx5. I recently found them on this website. Are they any good? This is the link to buy them. Not bad for price. http://www.rhdjapan.com/tein-flex-z-coi ... -nb8c.html

Put these in during the week, done around 200 km on them now including a Nebo-Glorious-Fernvale loop.

They are brilliant. I've got them set to 9 clicks to soft at the back, 8 at the front and my wife was more than happy as we ran around on the crap roads around Brisbane's south, despite the car sitting probably 10-20 mm lower than I'd really ideally like. The car gives the impression of being quite busy with dips and variations in road surface, and whilst movement is transmitted to the cabin there is no 'shock' of impact - it's all very controlled. It's definitely improved over the Bilsteins and standard springs that were in there. On the freeway it's borderline cossetting. Need to be a little careful over speed humps, but if you're sensible, it's fine.

After having them installed they were set to full hardness so the car was bobbing and jiggling about something chronic, but again, no harshness was put through to the cabin. Full softness is a bit too floaty and gets a bit "out of sequence" with surface variations so you tend get tossed around a bit more.

Primary ride (dealing with stuff like those horrid hard rubber black speed humps at shopping centres) is hugely improved, more evidence for my suspicion that Bilsteins are weak in this area.

I had it set to 8 to the soft at the rear, and 7 to the soft at the front for the Nebo-Glorious-Fernvale loop and it was epic - I wasn't more than 6 to 7 tenths and sailing through the 40 km/h advisory zones at the 80 km/h speed limit (truly, officer, I was) with absolute ease (on stock wheels, with fresh Bridgie RE003s).

I was expecting much better control, but the improvement in primary and secondary ride is a massive bonus. Rapt.

I believe they replace the Street Flex Coilovers for a about 3/5 of the price.
Only real difference is they are not re-build able, but at the price point who cares. They advertise them as having replaceable dampers anyway which are probably cheaper than re-building Street Flex.
Wish they came out when I purchased my Street Flex's.

Awesome, can't wait to receive mine :-) Is your ride height set at how they were received? do you know if that is the recommended height?

Cheers :beer:

Haven't measured them up since I had them installed, but I would be guessing they're a touch under what they were when I received them. I'd say the height out of the box is possibly around 320 at the front and touch higher at the rear, YMMV.

I've got some days off later in the week where I'm planning to do a little tinkering around ride heights and a little fine tuning on ride (reckon I'm pretty close to settled on the standard road set up), so we'll see how easy that is, and I'll try to grab some numbers to give you an idea. We're both running NB's so the numbers should carry over.

I'd say these would be very good for the road.
At 7F 6R kg/mm probably too soft for full on track work.

Cheers

My Street Flex at 7F and 6R are stiff enough for the track.
I have the standard SE 23mm Front sway bar and no rear sway bar with this combo.

Rear sway bar connected = no traction and guaranteed spins with the very equal front/rear spring setup on a NB8B/C chassis.

Great, thanks mate
