I got my clutch fork and pivot in this weekend and it feels amazing. I was having really bad lockout issues with my act clutch with streetlite flywheel. Switched over to a southbend stage 2 with oem flywheel with the velox clutch fork and it is 1000x better. Not sure where the root of my lockout problems was from but this set up feels really good so far. Fingers crossed though :)

We have some exciting news to announce again on this product line.

We have been working for the past 6 months or so on an even stronger unit using a better manufacturing technique, forging. Forging forces hot metal into shape which aligns the grain structure of the material in a better way than machined billet. We then heat treat and cryo treat these units to further improve strength/hardness/overall structure.

Below are images showing, through FEA, the difference from OEM, to billet, to forged. The scales are all set to the material's yield strength to keep viewing simple and easy. Purple/red is bad and blue is good as far as the stress plots are concerned.

The billet/machined units have and continue to work flawlessly in the market. The forged unit will (hopefully) be easier for us to keep in stock which was another reason for this move towards the newer unit.

We will work on having product images shortly.

Thank you,
Eric

Any idea of price range for the forged fork compared to the billet unit ?

Pricing will remain the same.

You did the stress analysis on the machined forks; are the machined forks deficient in some way?
Is there anyway to tell the forged unit apart from the genuine item?

With the numbers we are moving in the first ~year, forging makes sense for the long haul. It will also allow us to keep more in stock without running out which has happened with the machined unit multiple times. Like I stated, the machined units are not *in any way* deficient. While they are not as strong as the forged units, they are more than strong enough to handle the loads necessary to actuate the clutch.

Yes, they will look different. They are both genuine Velox/Verus items though... and we stand behind both.

Thanks,
Eric

I deleted my original post because of a typo and @Eric had already answered. Whoops.

when will the new forged parts be in stock? I need to order a fork and pivot very soon.

Time to install my new Exedy clutch / flywheel setup and I'm looking forward to adding the Velox clutch fork and pivot!

Captain Snooze 09-21-2017 06:31 PM

Admittedly, I'm looking forward to having to have my clutch replaced.

They're in stock and ready to ship.

Mine is getting installed with my new upgrades over the next week or so. Will report back with results. :)

Just passed the break in period on my new clutch setup - Exedy OEM pressure plate, Exedy Stage 1 clutch disc, Exedy lightweight flywheel, and Velox fork and pivot point.

WOW! I'm in love with my car all over again. The smoothness of the OEM pressure plate mixed with the beefy fork make shifting feel like BUTTER! I regularly drive Porsches and the clutch feel is superior now. My previous setup used the same OEM pressure plate - I can tell the fork has made a big difference there. I don't know if it's a placebo effect or a result of moving the transmission around, but even the shifter itself feels better, smoother when going into gear. I have knee issues and this has very much improved my driving experience.

I had my doubts at first about upgrading the fork but can definitely say it was a wise decision to go with Velox - this should be standard with every clutch replacement!

When my clutch or TOB goes out I was thinking about upgrading the fork aswell. You say the clutch feel is better than a Porsche now? Did you remove the clutch spring and do the clutch height adjustment as well or did just upgrading the clutch disc, flywheel, fork and pivot cause the change in feel?

I've been running the MTEC clutch spring - I couldn't deal with the soft, vague feel of the OEM clutch setup. Currently when the clutch disengages it gives out with no tension pushing back - the first time I pressed it in I almost put my foot through the floor. I think it's wonderful given the traffic on the turnpike every morning. I played with the clutch height adjustment and will continue to do so further until I find a sweet spot.

Porsche is known for their quality on all components for sure, the clutches are smooth but less aggressive and precise than I prefer. I'd say my clutch setup currently feels like a freshly honed Wüsthof knife slicing through vegetable matter as it if were air. I chatted with Steve over at Exedy about the ideal clutch setup - the OEM pressure plate spares my knee while the stage 1 friction surface offers slightly improved engagement with a bit more longevity for the inevitable track day. The upgraded flywheel is a must on all my cars - I love the quick response and I'm "that guy" who rev matches on the street. The only "drawbacks" are a slight jerk / bang when shifting hard (diff bushings need to be upgraded) and some reverberation transmitted into the car around 3,000 RPM in third gear when cruising - but that's to be expected with the sporty nature of the components. Next to no gear lash noise and honestly I wish there was more.

Got mine installed; and im running into some issues.

Sometimes, everything feels awesome. However, after I do a hard pull - sometimes the pedal gets really soft and I cannot shift. When this happens, I pump the clutch again and its back to normal.

Fluids are good, no leaks, slave cyl looks good, brand new ACT Stage 2 & flywheel installed by a local tuning shop that specializes in the 86 platform.

Any ideas? Pointers? We initially tried to bleed the system to resolve and that did not help. New idea is some sort of fork spring assist like on most EJs. - Picture attached for reference of what we're thinking.
