Really? I've had quite a few Koni and Bilsteins setups on various cars throughout the years, and I didn't think the AP1 Flex Z's were far off for ride comfort given the 10 kg/mm spring rates. The stock suspension with blown shocks rode worse in many respects, even with a softer rate. The Flex Z's were way quicker on track - on the order of many seconds a lap with a "fast" driver behind the wheel. I did find the shock adjustments to be very sensitive, so there's a relatively narrow adjustment range where things work well.


As to the other questions in the thread, the suspension worked great, but I actually totalled my AP1 after hitting something, losing oil, and the engine locking up almost immediately. So my set of Flex Z's will be for sale shortly.

Very interested in the Flex Z's if you plan on selling soon. I wasn't able to send you a private message since I'm a new member, but maybe you can message me?

I have to say i recently purchased a set of the tein flex and ihonestly love them. Its only been about aweek but ive driven proper s2 with oem suspension . Ive also had koni yellows and tein s techs. The flex z is great for tge price ..ease of installation ..and how easy it is to change the height of your car and dampness.. which is a trial and errir because no two S are 100% identical. You have to tweak for you. Not knocking the other struts. But these are def worth checking out. I live around the Jfk area if anyone is interested in going for a ride to check em out

Thanks for the informative review, I plan on picking up a set here shortly and this sealed the deal! Too much body roll on the track, these spring rates and dampers should help clean that up.

14mm of preload on 10K springs. Meh. You're probably fine.

You'll have a ton of compression travel and reduced droop travel. Make sure the wheel cannot travel enough to hit a body part before the shock hits the bumpstop.

Just installed these a week ago and I am impressed with the build quality of the set. I set the preload to 12mm as suggested by DefSport and started on 6 clicks from stiff, which is what TEIN recommends out the box. I drove for a couple of days but felt like the ride was too soft and very busy through bumps. I dialed two clicks to stiff and it feels like stock (149k on the shocks), which I'm happy with because I were looking for similar ride with height adjustment.

Got off the Blizzaks 2 weeks ago, and I'm finding that on spirited driving on hard dips, the rear wheels are coming off the ground, losing stability. Anybody having similar issues? It's as if the suspension has too much compression and the rebound is too slow to compensate for it.

How is Tein Z with 10k rate spring for daily driving? I need/want to buy a new coilover and Tein Z has a good review and it is a reasonable price.

I don't do any track nor race. It is just my daily car and drive 40~80miles per week.

Just want to lower the car and get stiffer for fun drive. Many people recommend Bilstein but it looks like it's back ordered everywhere and many people say too soft.

Or spend little more for BC Racing BR?

Please, trying to stay under $1000, I know there are lots of good coilovers but all that are too much for my use.

Thanks

UNDER $1000, I think the Flex Z is the only viable choice that I would think of.

Tein has a strange way of setting up their dampers. You might be fine. Worst case, you'll need to buy softer springs.

BUT...for $1200, I think Fortune Auto makes a pretty solid monotube setup.
