Which suspension to get?

[SpoonS]

I'm contemplating which suspension to get. Its a toss up between Zeal super functions and Tein super racing. They are about the same price, and i've never tried them before.

Does anyone have experience with either suspension?

thanks

No direct experience with either but what rates does Zeal use off the shelf on the Super Function? On their other DC5 chassis coilovers they are 10/10 and 12/12 rates which is just weird. It is like they haven't noticed that the DC5 has Macpherson strut at the front and an odd double wishbone/semi trailing arm setup at the rear.

The Tein site lists 14/16 rates for the Super Racing which is still a little front stiff for me. Both options are quite pricey, have you considered any European or US options?

Ya, the dealer i'm inquiring about the zeal's from said i could get whatever rates i wanted. The JUN DC5 is running this suspension with rates of 13/26. But whichever coilover i get i'll be looking to get somewhat the same as the Tein's 14/16. Yes it may be a bit stiff, but its bearable, and will be great for the track.

As for the european and us options, i have to stick with japanese for the sole reason that once i ship this car back home, there are workshops that can rebuild the suspension if needed. That just isn't the case with the european and us brands.

wouldn't you want good quality coilovers that you wouldn't need to rebuild in the first place?

a mate has Tein SRC on his S2000, have to say despite the silly spring rates, the valving seems to match it very well. Personally would go for European offerings at that level, but if you must buy Japanese, these are probably the ones to go for.

Under constant race use any damper will need rebuilding eventually, particularly with high spring rates and correspondingly high damper forces. It seems wise to plan for that eventuality .

The spring rates on the SRC don't seem all that silly to me .

Have you considered the Tein N1? They are double adjustable (not sure if the Super Racing or Super Function are?) and support nice rates for the DC5 off the shelf. I have been extremely happy with the handling of my car with 14/28 but I feel like it could do with a bit more rear swaybar and less camber at both ends. I would urge you to go a bit higher in rear spring rate than 16kg/mm.

Aren't Tein N1's crazy expensive? Coz don't you have to buy each individual suspension +camber tops +springs ++ other stuff?

ZEAL Function X

[SpoonS]

ZEAL Function X

Isn't the function X a step down from super function?

[lukits01]

well the way I see it,
Tein = a company specializing in suspension
Zeal = a brand of suspension made by brakes specialist
why would you want a suspension made by people who's core business is brakes?

jeebus, you're much bigger fan of stiff spring rates than I am, mate.
I wouldn't touch anything with 2 digits let alone 28kg/mm!

eddie which suspension you running atm?

[3r1k]

Give Zeal Super Function R a try if you want a track coilover.

Or Ohlins? Quantum?

I'm using Tein super streets.

The super function r is quite a bit more expensive then the super functions.

No such thing as quality coilovers that will last forever. High end watches need regular servicing too

Question for u (not picking): why European offerings over Japanese offerings ?
is it a price thing liek Honda vs BMW thing?

Wouldnt you take into consideration the experience the particular brand company has with the car and how that influences the overall choice of spring/damper setup?

yes of course experience is a valuable thing. IMO the European brands have more experience in that regards. They'll race just about anything, anywhere and have such a varied road conditions other than silky smooth circuits and this shows in their suspension setups, their EP3/DC5 kits don't usually go far above 5 or 6 kg/mm spring rates. Whilst the Japanese seem to like their rates very high. I don't think specializing in a particular make of car is as valuable as specializing in making suspension itself. It's not like double wishbones or Mcpherson struts is unique to jap cars, hell most times they are copies of inventions in Europe.

not so much about price, Bilsteins and Konis offer great entry level products.
In my books superior to most coil overs of the same price.
(they just don't go very low )

Looking at this price list LINK It looks like the N1 dampers are about 60,000¥ each, and you will need lower brackets at the front and top mounts at the front and rear. A set of Swift springs is about 4-500 dollars at the outside, Mugen lower brackets can be use with Tein N1s and are around $800 I think. You will probably want to change spring rates down the track in any case if you are racing seriously so you should expect to outlay some money on different rates .

This LINK shows the Super Racing are around 400,000¥, that seems comparable to the N1s, they are at least in the same league cost wise.

Rates of 5 or 6kg/mm at the front or rear of a DC5 are barely enough to keep the car off the bump stops at stock height . The stock rear rate is somewhere in the region of 7kg/mm I believe although obviously progressive. I don't think any circuit in the world is bad enough that rates like that would be faster than something a bit stiffer.

I don't like stiff springs that much, but I am a big fan of rates that allow the ride heights that I like with big tyres . For a real race DC5 chassis my (limited ) experience suggests that nothing below 10kg/mm should be considered.
