HKS GD Pro Twin Clutch Type K, Does anybody using it??? Options

[Magic]

I`m planning soon to replace my Clutch(Disk,Cover and Flywheel) and i found a very nice kit for my ST-205 from HKS "GD Pro Twin Clutch Type K".
Is somebody using it???ANy comments?

[Lar-]

I've using the GD Pro Twin Plate on my ST205 for 6 months now.
So far so good. A little bit noisy I would say, but I guess it's natural for any twin plate clutch.

The feeling during every gear change is very solid especially when you are slamming down the 3rd into 4th.

Also, I have no problem "licking" the clutch to take the car off on any slop or a bridge.

Lar- Thanks a lot for your reply,I check out your profile your car looks fantastic about the clutch now did you install it with the flywheel???Did you install also Quickshift???how do you feel it at downshift???Also did you notice any loss on lunch???

Thank you

[Lar-]

Yes, I got the light weight flywheel(it comes with a full kit) as well.

I didn't install the quick shift. I wanted to though, but my mechanic said that the quick shift for my ST-205 would be a waste of money as the difference in the stroke is not that greatly noticeable compared to the standard shifter.
I am talking about TRD's short shifter here.

I don't know about C's short shifter, but I heard that it is solid and sharp.

Feeling at downshift??? ==> Very smooth(can be seamsless if you are able to sync the clutch paddle with the gas paddle) and solid.
Very very little RPM "pick up lag" during high RPM gear shifting comparing to the stock clutch kit... Stock Clutch tends to "slip" during high RPM gear shifting.

Any loss on launch?? ==> NO!! and if your car is still running with the stock 16" wheels. A "Road Bullet" I would say.

I am very happy with my GD Pro kit...

Lar- thanks again.
I`m really thinking about it and i make a research between HKS GD Pro,Cusco and TRD Clutch and i think i`ll go with the HKS GD:)
Do you remember how much did cost to you the HKS GD Pro full kit??(including Flywheel) also how much do they charge at your country for installation??Just to compare nothing more.
I`m also thinking to buy the quickshift(TRD) but not now cuz i want to see how much difference i will see with my shifts after the installation of the Clutch.

[Lar-]

I think you can leave the TRD clutch out because it's only single plate and again the performance is only a slight different from the standard clutch.
For me, TRD is always the last choice for any performance parts.

Another 2 brands that you should look at is the OS Giken Twin Plate and the Ogura Twin Plate. These 2 brands provide high performance and reliable clutch kit as well.

I paid $1,875(Aprox.) for the full kit.

[Magic]

Hello Lar-!!!
Thanks again for the information i will make my research about OS GIKEN and Ogura Clutches.
You purchase the HKS from a local dealer or from Online Shop?

[Lar-]

Hello Magic...
You got one very neat looking, especially the engine, GT-4 as well!!!

I bought it from the HKS local dealer as I couldn't find any online.

Many times that I envy those Supra users, they have a lot of nice.. nice.. high performance toys to play with.

Our GT-4s high performance parts are more like specialties... rare&high priced:(

[Magic]

Lar-

I like we are talking about a common issue!!!:)
I make my research so i`m between 3 clutches now!!

First one is ACT Single Clutch with Jun Light Flywheel(Not UltraLight).
Second is OGURA ORC409 Single Plate.
Third OSGIKEN R2CD Twin Plate.

I must said that i`m in love with the HKS GD Pro Twin:) but i`m running with stock internals and stock turbo and for the moment isnt a good choice.

Now about Prices look what i found:

ACT Single Clutch Kit 613.00 USD
JUN Flywheel Light 409.00 USD
OSGIKEN R2CD Twin Plate Kit (Flywheel Included) 1.058 USD
OGURA ORC409 Single Plate Kit (Flywheel Included) 1.064 USD

What I`m really thinking is not to install Flywheel cuz i drove Tufy`s car(check his profile in 6gc.net under GT4) and i was not happy with it in low RPM and i think its a matter of Flywheel cuz its too light that cuz loss of torque,what do you think?

Thanks

lol, danm you gt4 owner's

[Magic]

Whatz Wrong drdos???

Hi Magic,

If you have no future plans for your engine to go over 350hp, I suggest that a Single Plate Clutch kit would suffice your need. You will under utilize the Twin Plate Clutch potential and it's a waste of money as well.

Also, a single plate clutch is easier to "drive" with. You will not have to adjust your clutch paddle releasing habit.

I have to adjust mine for quite sometime to get the right timing. I stalled my car a few times at the beginning as well... haa.. haaa.. but after a while when I got used to and "learned" the clutch, it's a "whow!!" experience. It's like I'm driving a different car.

I don't feel any "loss of torque" during the low rpm with the GD pro. Most "come with the kit" flywheels are not as light as those flywheels that are being sold seperately, so don't worry. This would be one of the reasons why I want recommend you to get the clutch kit that includes the flywheel.

Something about flywheel: Flywheel is like an enery storing(eating) wheel. A heavier flywheel would store more energy(created by the engine), thus releasing or flowing less energy(created by the engine) to the drivetrains. Less energy to the drivetrains means less hp to the wheels.

A lighter flywheel would be vice versa.
=> storing less energy.
=> therefore, releasing or passing more energy to the drivetrains...
=> more hp goes to the wheels.


As for your new 3 choices;
I would choose the Ogura Single Plate.

However, if you still insist on getting a Twin Plate then I would suggest you take a look at 2 more choices.
1. The Cusco Twin Disks Clutch.
2. The ATS Twin Disks Clutch.

I noticed that you you want a high performance and a "solid" clutch gripping feeling, but yet you still want to maintain that easy ease driving pleasure.

I suggested those 1. and 2. because the friction disks are both carbon faced(mixed) instead of copper(mixed).
Carbon mixed disks will allow a much easier "slipping" or "licking" the clutch during stop-go traffic or on slop launching.

Please do not rush to spend $1,000 away. Take your time to select what's best suited your need.

Hello Lar-

I dont plan for the moment to run above 350HP so the single on its the correct move.
A friend of me who has MR-2 3SGTE he is running with 500HP.He is using internals(Jun camshafts,pistons,rods,Greddy TD06 etc) he is just running with ACT single clutch!!!!!!
I asked him and he said that he is really happy with it and his clutch is running more than 35000kms!!!!!
I`m thinking to go for it.
I think your idea for a clutch kit that includes flywheel its correct cuz i dont think that its a good idea using a brand of clutch with different brand of flywheel.
I'm wondering about Cusco Clutches,many people told me that they are not reliable what did you hear about them?
Also Cusco Clutches are very cheap here....hmmmm...tell me what you think.


Thanks

Hi Magic...

Please consider.. we are running on all 4 not just 2 wheels....

Sorry my man... I have to leave right now...
I will get back to you soon ok...

Cheers...

[Magic]

Hey Lar-

This is right we are running on all 4!!!
I will not install the flywheel:( so i`m really thinkin of ordering the ACT (organic) Single Clutch with TRD QuickShift:) cuz i really wnat to improve some things about gears shifting!!!!!
Hey do you got a hotmail account on MSN messenger?

Something out of subject i`m planning to get Endless Break pads for my car,what do you think about them?

[Lar-]

Hi Magic....

If you have chosen what suits your need then... go for it!!!

I don't use the msn messenger, sorry my man...

About Endless Brake Pads... Go for it!!! It won't dissapoint you.
You can just use the NA-S grade, it's more than enough for street use.

The CCM grade is superb, but it will "eat" up your disk brake rotor surface pretty harsh. Also you have to WARM the brake pads up before you can do any hard braking, this will pose quite a problem(slipping or fading) during in the morning, on a cold night, and driving in the rain. CCM is more suitable for circuit racing and not street use.
Hope this helps....

Cheers...

Hey Lar-!!!

Where you been m8?
Well i have decide about my clutch,it will be ACT!!!!I`m not going to install Flywheel.I also order the trd quickshift!!

Yes its very expensive!!!!My engineer said that he will do it for me for 160USD which i think its a very good price but i also asked other guys and the price they are charging its 300USD!!!!!F**!! The clutch will cost less at the end of the story!!!

[Lar-]

Hi Magic....

I was called up to a metting in a sudden...

Yes... yes... please let me know how you feel about the new clutch...
But.. hey.. please don't forget to run-in your new clutch for the first 100km(to be safe). Be patient, don't go "slam&bang" your new clutch when you take your car freshly out of the garage. This is to let the new clutch disk to make a full surface contact with the flywheel.

This goes as well for your new brake pads.
If you had changed your brake pads previously, you would had noticed that the surface of the newly changed brake pads and the disk brake rotor would not be in full surface contact for the first few days.

A little run-in would help you get the highest performance.

Cheers....
