Default WoA Stage4 Impressions

It's finally in!!

At first I was a bit worried that a 6 puck was going to be a PITA to drive on the street. I almost stalled it pulling out from euroclass, but was got used to it about 5 minutes later.

This clutch does bite alot harder than the stock clutch, and even Rocketships setup(WoA Stage 2) but it can also be easily modulated as much as I want. I just need to be more precise with the uptake. If I get lazy and am not on my toes, this clutch will grab hard and let you know with a big jolt.

I am amazed at how smoothly this clutch can be driven, it can be smoothly slipped with only a very small amount of shudder. It can be driven 'almost' as smooth as stock, and someone in the passenger would not guess that it's not OEM.

Pedal feel is much heavier than the stock clutch and a fair bit heavier than Rocketship's Stage2. But it's not quite as heavy as Lucas' twin plate. Now that I am used to it, I really like it. The thing I like most about this clutch is that it engages really low. Basically right off the floor, the way a clutch should be in my opinion.

The feel of this clutch may change over time as the clutch is broken in, but for now I am very satisfied with it.

Now onto the Flywheel. It is 15lbs compared to the stock 25-26. The car is much more willing to rev and feels alot free-er. It's picks up the rev's really quickly now and just wants to keep climbing. It feels like i've gained an extra 15-20HP. Double Clutching and rev matching is much easier. This is definately a worthwhile upgrade.

The only downside is the chatter. It can only be heard at idle if the A/C is on. Or while cruising slowly in gear close to 1000rpm. It is quite loud with the A/C on .. and does not sound very "refined". But it's really not too bad and is a small price to pay for all the benefits.

I won't find out how this thing launches until it's fully broken in. It will be up for some punishment when the big turbo goes on.

A big thanks to JuanM, Lucas and Louie and the boys @Euroclass.

Default What's wrong .. can't handle a man's clutch?!! ;)

You'll have to try it out again when it's fully broken in.

Default LOL - If I didnt do so much city driving in traffic I would go Stage 4

Will try it out again when its fully broken in as you suggest tho.

having tried Rocketship's WoA Stage 2 and your WoA stage 4 tho I am pretty sure that the Stage 3 will be perfect for me - will easily handle the KO4 motorsport power when I put it on and will still be suitable and tolerable for daily traffic driving.

Do you know what the psi your pressure plate is or what type of setup it is?

Dual Diaphragm 3800psi pressure plate. 6 puck ceramic/kevlar.

UPDATE: it's actually a 4200+ psi pressure plate.

Default Thanks, I was just checking to see what the PSI was. Since you called it a stage 4.

I have a custom WOA clutch which is a dual 4000 lbs setup. Looking to change the disk out to a full kevlar/kevlar setup soon, to hold the hp/tq when I put on the big turbo.
