Default REvalving Teins:need advice

Posted in Suspension thread as well. Hoping to get some replies.


I bought a new set of Tein Force Flex coil overs 4 years ago. They now need to be rebuilt. I have them disassembled and ready to ship off to California. I've downloaded the service form and need advice.

I am one of the top local fast guys and have won multiple local championships (4-5) & events….Auto X, Rally X and ice racing….all on these coils, in my daily driver (a 2002 bug eye).

They were my first set of coil overs. I am still learning about the suspension game and wanted to take this opportunity to learn from those here who have had their coil overs revalved. I don't really even know where to start with regard to asking Tein to revalve them to certain specs.

The ride was pretty harsh with the stock settings that came with it but I have nothing to compare to as far as coil overs go other than stock suspension (mushy). Hoping someone from the crew can give advice or direction. I also use hollow cobb sways, Kartboy end links, extensive diff., tranny, subframe bracing as well as strut tower braces. Car handled like it was on rails. Give me some idea what my options are.

Please be gentle.

My understanding is that Tein's have always been valved for smoother Japanese roads. That is why they are so harsh on the streets in the USA.

Yep, I got that. Just looking for info on getting them revalved to provide the dialed in tarmac feature along with a bit more cushy ride on our atrocious Alaskan roads.

I would revalve them into anything other than Teins if you want "a bit more cushy ride".

H&Rs maybe, or KW V1s?

I agree with buttdyno on the teins going bye bye, however no GD will ever ride well.

Cheers,
Rob

LOL,

figures.

I do appreciate the replies folks. I sent them off today. I'm in graduate school and can't work right now so I will most likely just ride these out until I can afford to go for the gusto.

Being the Flex you can adjust the dampening on them to accommodate daily driving and track type use. I had a set in my car with the EDFC unit till they needed a rebuild. I would set them full soft for daily use and to 5 on the EDFC for track use, 0 being full stiff 16 being full soft.

So, not a lot of helpful info here for me before I sent them off. I appreciate the replies though. Silver Bell, I lived with the Flexes for nearly 4 years. I was well versed in the 16 settings.

Anyways, just to inform folks in the future, who want to do their own custom TEIN revalve, I will give you a document of my experience.

I spoke with the service department today. I had left a message after hours the very day before and they called me back today. I spoke at length with the helpful technician. He told me that upon the receipt of my parts in the shop that he would give me a call with the post tear down inspection report. We could go from there as far as exactly what I wanted with regard to the valving. The overhaul (service) is $100 and the revalve is only $25 more. He said they could go 10%-20% softer….or further with the shim plates. He recommended that if I was going to continue to track the car to not go any softer than 20% from original settings on the valving but to start adjusting spring rates (i.e. buy different rated springs). I hope that makes sense. If not pm me and I will try to explain it better.

Very pleased with the personalized service I was given by them. Tein seems to catch a lot of crap here because they are so stiff for American roads but if you don't ask for different….you'l never know the possibilities out there. He said they generally do 5 revalve jobs per week, so the turn around will be quick. They even were willing to ship insured USPS to keep me from having to 2 day air via UPS or FED EX. Dynamite service.

Doesn't seem like you need to change much Looks as though they work pretty well for you in competition. I had Tein HA's on my bugeye and they performed well at a few auto-x's and track days. A lot of people don't like Teins, but they worked well for us

good luck with the rebuild.

I had great luck with Tein's service when I revalved a set of Flex for my '04 STi back about 5-6 years ago. They have a very digressive rebound valving stock, which is not at all like "all of those cheap chinese/japanese coilovers" people bitch about after reading Dennis Grant's crap. Also, despite the single adjustment, bump valving was barely touched when sweeping through the 16 clicks on rebound, especially at low piston speeds.

I actually went quite a bit softer in the rear on compression, as the STi was more like a Camaro than a WRX imo. I think I ended up with 10/7k springs, big front bar, no rear bar. This was a dual purpose STU/ESP car, that was also tracked a few times.

NASIOC has been complaining about Teins since wayyyyy before DG's site. You were here A local guy has a former-STX car on 8k/10k Flexes and described it as brutal
http://forums.nasioc.com/forums/show...89&postcount=1

I will be interested to see what "20% softer" means in terms of actual ride quality. If Tein was capable of building something that both performed well and rode well you'd think they'd have done it by now.

But ride quality is really subjective, too.

I hear ya…..but while I've never personally experienced DC roads myself. As rough as they may be…..I will put every dollar I've EVER had access to that they pale in comparison to Alaskan roads.

We'll see what happens.

I will say, on the softest setting….my kidneys didn't bleed.
