Hi, i have 2000 dollar to spend on coilover, but i don't know what brand coilover is best and good performance, can u guys tell me or show me a picture too? thank u guys very much DO u guys think JIC coilover or tein coilover or the HKS coilover, which is better?Also what brand front and rear strut bar should i get, and what brand sway bar should i get?thank u guys

 

TEIN + EDFC. but that's just me... might be a bit more than $2000 though.

 

i think hks is 30 way adjustable and both jic and tein's are only 15-way correct? Can't go wrong with JIC's man... forgot where i've heard this but i think they pulled over 1.00g on the skidpad and a pretty fast slalom when they test there rx8.

 

i hear zeal is the way to go but may be a little over your budget.

 

i'm not sure zeal has an rx-8 application yet. Tein Flex is good, very street-worthy.

 

Tein's is 32 way adjustable, but I never tune down to every 1/32. just 1/16 is more than enough for me.
The JIC's are monotubes I believe. Better for track? But less durable (not that its fragile, but compared to non-monotubes, they are less durable)
Teins are more streetable, (trackable, just not as good as JIC I think?) but more durable than JIC? Dont know much about HKS.
Im sure most places you can get either tein + edfc or JIC installed for less than $2000.

 

the zeal xs is out

 

Are you using the 8 for street & track, track only or street only?

IMO, you're decision should be based on your answer to the above question.

My personal choices would be as follows:

Street/track - HKS (very adjustable)
Track only - JIC (a bit hardcore)
Street only - Tein (stiff, but still liveable)

Just my 0.02c.

 

i have the TEIN Flex coilovers with the EDFC as well and I love them. i will try to post pics if i get time.

 

what is EDFC?

 

EDFC stands for Electronic Damping Force Controller. It is used to electronically adjust how soft or hard you want your suspension rather than doing it manually. It also gives you 32 diff levels rather than 16 without it.

 

Do i have to pay extra money to buy that or it come with the Tein Coilover? If it cost extra money to buy the EDFC then where i can get it and how much it cost? thank u

 

you have to pay extra for it. It retails for $380 from TEIN and the type flex coilovers retail for $1540. I got the coilovers for $1280 and the EDFC for $320 from rxecret7.com. thats 1600 plus $45 for regular shipping. You would still have $$$ left over to put toward other mods

 

when people say tein flex is very street-worthy, what does that mean... how does it compare to stock suspension?

also nojooc, when you say that tein goes well for street but HKS is better for street/track, what do you mean? how does the HKS on street settings compare to tein flex on street settings? Which HKS coilovers are there, or is there only one?

 

Street-worthy means the ride quality is pretty good. I think the Teins are the most versatile.

 

HKS makes only the Hiper unit for the 8.

I believe it's the best unit if you're going to use the car for street and track since it is multi adjustable.

This would be my choice if my car was a daily driver which would see occassional track use.

If the car is never used on anything other than the street, I would go with Teins, purely for the comfort aspect.

 

I have the JICs and love them. I'm into autocross so I can live with the higher spring rates. A little rough over pot holes but I don't notice much difference from OEM over the small stuff.

Also, the JICs FLT-A2S have a softer front spring rate (448 lb/in) as the Tien FLEX (504 lb/in) and the JIC is softer in the rear (280 lb/in) as compared to the Tien (336 lb/in).

 

There is also a JIC FLTA2H which has slightly higher spring rates than teins in the front. 10kg vs 9kg. Same rear spring rates

 

I talked to JIC before ordering and they recomend the "H" spring rate coilovers only be used for track as they "would be very harsh for street use."

 

i currently have tein springs but will ditch them for tein coilovers later this winter.
i have no complain or passengers form the tein springs i have now.great ride comfort

 

The key to the Tein coilovers is that you can adjust damping on the fly, without having to jack the car up. Unless your car is for track use only, this is a major advantage. And even if you see a lot of track use, you are not going to be at a disadvantage with the Teins vs. the other similar options. I believe the Apex drift RX-7 runs on Tein Flex coilovers.

 

The JICs now come with adjusters that are accessable from the trunk so you no longer have to drop the rear coilovers. Still not as convienient as EDFC, but an improvement.

 

Zeal has just released their line of coils for the RX8. They are available to order. They take 2 weeks to build and 2 weeks to ship here via air freight at no charge to you.

There's the Function Xs which is designed for optimal street ride quality while greatly improving handling over stock, and then the Function X which is 30 way adjustable with more aggressive valving and the detents to balance the car to a "T".

Here is a pic of the Function Xs for the EVO8:



Here's the Function X:

Basic things to look at when purchasing a coilover:

Average lifespan specific to your region with these coils.
Construction of uppermounts and quality of bearings/bushings.
Quality of welds and coatings resistant to flaking or peeling.

Most important: CUSTOMER SERVICE

I have an extensive amount of experience with JIC and the type of company they are. They have repeatedly refused to warranty legitimate claims and have severely inconvenienced several of my clients as a result. This is why we completely stopped carrying their line of products. It's like one day they are cool and the next they are not.

I'm sure many of you have read about the claims and complaints against JIC USA. I would look at their products with caution. Not because they don't work but simply because you might be the one person they just don't want to take care of.

The sad part is I WAY Opened up the Mazda community to them thru product awareness and education. I did like the product until we started getting premature failures and a lack of willingness to comply with their stated warranties.

I moved over to Zeal simply because you have many many options. Rigid mounts, Pillowball, aluminum casings, steel casings, street ride, race performance, custom valving in US, and INTERNAL REPLACEMENT of Damaged parts for quick repair.

Tein and Endless are probably your two most servicable Japanese coilovers in US currently. And I emplore you to email or call Endless USA they are so damn hospitable it's ridiculous. Just read their FAQ's and ANY CLIENT THEY HAVE, you'll see the unanimous response.

Laters, Rishie

 

I handle all sponsorships for Endless USA so if you have a proposal worthy of such sponsorship pricing please inquire. I would be more than happy to set you up. Zeal coils just released a month ago in Japan i believe for the RX8.

Thanks, Rishie
