Try this one:

The 0° c-hub will provide more steering.

Yes, this is must. I measure the kicks up plus with 10 degree C hub, the total castor angle is about 15 degree, it's too much for on road car.

Also, I found the problem finally. I'm using on road engine, the default gear ratio is to fast and no engine brake. I will try to lower the gear to 15T/18T. Thx guys

I would also revisit your diff fluid weights. They look to be 'backwards' in the sense you have heavier fluid in the rear vs the front. This should cause a very noticeable understeer.

I tried 15000, it's loose enough for tight corner, but the weight of car and lower gear ratio create more forward momentum, I guess.
My friend use the GT engine in 16/19T in same setup, he can keep on throttle
corner by corner.

Not really this reason. F. diff too lose will lost control. I've found its gearing problem.

Hi!The tension is up to you, depending how you want it to feel... If it feels too punchy like On-Off kinda feel, you could check if you have a lot of tension but you might also have no split in tension between the 3 springs.

IF all springs have same tension on top of being set tight, the clutch should engage very suddenly. For a smoother engagement, you could try setting each spring with a different tension. For example you could try 1.5, 2.5, 3.5 turns from your 0 point...

To set your 0 point, try unscrewing/screwing your set screws until the spring just starts touching the flywheel (you have to do this with clutch off so you can see the back of flywheel).

I started with default setting in 1, 1.5 and 2 turns. I will try to adjust more, thanks!

the 9886 pipe with short conical header would be a good choice. Or a 2046 with short header too.
