Default Tein Flex vs. D2

K, I getting ready to by a decent set coilovers for my 95 gsr and I would just like to get everyones opinion. I'm looking for a decently stiff ride, and I've heard good things about both set ups. I know the D2 are going to have a higher spring rate in the rear. I really don't know that much about coilovers. I'm looking into the D2 because they are pretty cheap compared to the Teins and they both can be rebuilt. The D2 has 36 way dampening and rebound adjustment vs. the tein's 16. Not 100 percent sure what that means? I was thinking about the Ra's also but that would require me to get the Type R LCA, atleast thats what I've been told. I would like to know why if that is true.

D2's...you save money and get the 36way adj damper..i've read plenty of good reviews for them....the teins do have the name behind them..but the D2's are good too..

You make it sound as if this "36 way" adjustability is a major selling point. Does D2 provide a shock dyno chart to show that each of the 36 levels of adjustment are indeed different?

If you have no evidence that the adjustment levels do anything, you're simply buying into the hype.

Oh, so you have no evidence to back up your claims. Also, it seems you don't even have any first-hand experience with said coilovers.

This is a technical site. If you're going to make claims, please have evidence to back up these claims.

I personally don't even think it should be a question between the two. Tein has what is easily one of the best customer service teams in the industry, numerous championships, and proven combinations. D2 has 32 way damping adjustability and that's pretty much it.

I've been nothing but impressed with Tein's products and their quality, but there are high-quality options out there for much less money. PIC offers shock dyno's on every setup they offer and have rather extensive testing both on the track and on the street.

The 32 click of adjustment probably do not adjust the shock any more than the 16 adjustments that tien's have. Most JD, including Tein, have a view small range of adjustment. There really is no need for 16 or 32 adjustments on most of these shocks because in reality there is only a small range of adjustment.

i had tein flexs on my dc2 that are now on my eg..... they are great coilovers, and can be VERY stiff if thats what youre looking for, but trust me it gets a little annoying after a while. if youre not sure what the dampening adj. means then why are you so concerned with it? it would be alot easier for someone to learn basic suspension tuning on 16 adj. rather than twice that. and as the others said, the adj range is probably about the same.

another selling point for the tiens is the availibility of edfc - electronic dampening force controller. this allows you to make those adjustments from inside the car while driving, so you can really get a feel for what its doing. this, IMO, would be a great tool for someone who is leaning about suspenion and tuning. you will be VERY happy with any tien product

well thats why i said it might be worth it to save up for the better product.... i really dont know his knowlege of suspension or if he will be using it for what its desighned for or just slammin his car. but if he is looking to learn how to set up his suspension and say, autocross.... it may be worth the extra money. just throwin all ya my opinion, thats what this thread is for right?

EDFC Is overpriced and worthless, why pay 300 to 500 for something that takes 5 mins to do by hand.

I wouldn't go that far. I know people who have bought Flex's and had them revalved to RA specs with RA springs just for EDFC compatibility. Different driving scenarios require different suspension setups and if you encounter situations that would benefit from having two different setups on the same track, then the EDFC makes this possible.

And what would be the differnce in adjusting it manually, I do this all the time, pull in the pits change the settings on my konis in less than 5 mins jump back in the car and run some more laps. I can't image changing you shock settings while you are driving on course....

well this guy doesnt seem like hes gonna be doing too much track driving, and why would it be so bad to hit a few buttons on the straight so you could not have to pull over, and then just do a second lap with differnt settings on the fly? and its not overpriced

it is overpriced.

sure, it would be nice for a machine to stroke my ***** while i'm wacking off, but i'm not gonna pay an extra 300-500 bucks for that machine when i could just use my other hand.

it's unnecessary. it's one of those things that uninformed people brag about to uninformed people about, and feel good for about 3 minutes. absolutely useless, ESPECIALLY on the street. I can't remember the last time i adjusted my shocks for daily driving. i think it was when i changed spring rates...

Now thats funny...

Tein makes nice stuff, however most of it is overpriced, having ridden in a few simular cars with Basic's and SS, I think my car with Koni's and stock springs could out handle the basics and hang with the SS's. For what the do they are overpriced, Now If my only Choices in suspension where between Tein and hte OMNI/D2/Ksport etc... Clones I would choose tein in a heartbeat.

well with my flex's it nice for me to be able to switch settings on the street. they are rediculously stiff when set they way i like them for spirited driving, way too stiff for my commute to school on the shitty northeast roads. but on my commute towards the end i get to a nice little twisty detour and thats when i hit preset 2 and tear it up. for me it was worth the investment. i only paid 250 shipped.... idk whos selling for 500 THAT is overpriced. i had the extra money so for me personally it was worth every cent.

depending on whether you need to upgrade to pillowball mounts (for the SS-P/EDFC users) or just need the unit, the cost can be up to $500 more than the suspension sans EDFC.

i guess if you really feel the need to "change damping settings on the fly" you should get one. I never have that need, i guess. then again, i never really feel the need to "tear it up" on the "streetz" (y0). get to the track, tune damping. leave the track, go back to initial setting. drive to work on whatever shock setting i left the track with.

yea i hear ya, dont get the wrong idea though im not some *** who carelessly flys around... where me n my freinds go and up by my school is DEAD reall backwoods ****. once we hit the straights were back down to like 50 again. i drive in alot of different conditions on a daily basis, and theres only one track around here that has an open track day maybe 2 times a year, and then theres autox, which i love, but thats just something totally different you know what i mean?

Thanks for all the replys the main reason I whant to get the flexes is cbecause I already have the edfc, my friend donated it to me after he sold his set. There will not be a lot of track time maybe only during the summers. For sure I am gettting the Teins, just waiting and saving up.

I have D2's on my S2K. The spring rates are quite stiff but I also like it that way. The damper is actually very adjustable. At least on mine is goes from cadillac roll to don't budge. And don't budge is quite stiff. Didn't make the Mrs all to happy. It did take a while to dial it in right as there are 36 friggin positions. Also there are NO instructions on how to setup the adjustability correctly. You can't go from all the way up to all the way down. You will break it if you go all the way up or all the way down. It's basically the 36 "turns" in the middle of that. So be careful. It something like 6 full turns from all the way up is max. It will turn 2 or 3 "drip" marks past that but it will damage the unit if you use them, at that point the piston will jam and that is very bad.

Also I've used Tein on my civic and honestly I wasn't happy with them. I went to GC's with custom valved Koni's.

Oh yeah to the guy who posted 2nd or third or whatever and asked for shock dynos. That is in the very top post.
