Our sequential conversion to the Graziano will work with the GM ECU and won’t have any fitment issues. Delivering the first couple conversions to customers in the next couple weeks - hope they will be up and running shortly afterward! https://hcfautoparts.com/paddle-shift-conversion Best, John

Video of the final product, tested and programmed, below! My hope is we'll see customer installs sometime in Q1 and the kit in widespread use soon thereafter. Anticipating varied end uses, we paired the base tune for the kit to 4 different clutches: - HCF Kevlar clutch/flywheel - for street...

Hi Mark, Thanks for the kind words! To clarify, the pricing on this particular 6-speed is driven largely by the need to make several parts one-off to complete it. CIMA will still support the gearbox as needed, but isn't maintaining an inventory of parts or actively selling the unit. Best, John

I agree with Ken - likely the shifter. Drop gear has no impact on what you’re describing; nor would synchros - if the fluid were the issue you’d have problems with shifting into other gears.

Dan - the shop advised you wrong. Not being able to get back into first until the car stops is NOT a characteristic of this gearbox. I speak both from personal experience, having more than one in my own car, and from feedback from numerous customers. Best, John

Mark, We are working with Wanni, and CIMAs distributor for the North American market. Please feel free to reach out to us if we can help - [email protected] Best, John www.hcfautosport.com

John - a lot of nice options out there for front engine, rear drive cars out there. How does this new option help those with a mid-engine layout? Best, John

Last one we shipped was 124.7kg. Dry, but included the pallet.

DCT would probably save 10-20 pounds vs the clutch/flywheel setup in a traditional gearbox. From the DL800, but the clutch size and weight in the Corvette DCT's should be basically the same. There won't be 8 gear pairs, by the way - the layout in the DCT is different. In a 7 speed DCT, for...

Mine was 2825 with a half tank of fuel.

100% - that's exactly the way to do it. It would be a nightmare to get into a project like that, and find that you were missing a dozen sensors you couldn't source anywhere but a dealer. Recalling some research into DFI Cayman swaps, you wind up needing unexpected parts to make these work. In...

They did, but judging by the age of the gearbox platform used, this will be many years down the road. I also suspect the Corvette DCT will have more sophistication and be more involved to transplant. Specific to the LS-PDK conversion - love the idea, but it’s hugely expensive, and uses a est...

We've taken deposits from several owners and are proceeding with the conversion kit. There's a window left to add to the initial order for anyone interested. Please reach out to us at [email protected] if that's the case. The cost of the kit will increase to $12,000 for individual orders...

That’s exactly right. With everything that’s tied into the can-bus, you’d find yourself with unexpected items like a second instrument cluster and door handles in a box in your trunk (as the conventional-to-DFI Cayman conversions found) to get it to all function correctly if you tried to...

Thanks Cam! Since there are so many different steering wheels owners use, I expect we’ll see some variation in how the paddles attach. Assuming there’s a quick release hub, an ideal spot would be to mount with a bracket making use of one of the existing bolts running through the wheel.

For those of you who have inquired, these are the wheel-mounted paddles we anticipate supplying with the kit. They are an OE production unit of high quality. For those preferring a strain gauge / bump stick configuration, that can be accommodated on a one-off basis as well.

By the way, we offer transfer gear sets in a 1.04, 0.90 and .76 ratio depending on your intended use. The ideal match for a street/road course car is the 1.04 combined with an overdrive 6th gear (which we are waiting on a part from Graziano to finalize). For those willing to sacrifice some...

Many thanks for the review, Frank! I'm glad you're happy with the gears and they've proven to be a good match for your use. That type of road course driving is exactly what the 1.04's were designed for!

Thanks Mario - sent you a PM back. Hi Joel - it's actually the GM products (in particular the GM ECU and electronic throttle) the factory has the most experience with. That's what all the testing was based upon. I expect it to work quite well!

Ken, Similar in that they are both hydraulically-actuated systems that automate the gearbox. The Magnetti avenue is internal to the gearbox and was the first one I explored. Unfortunately Magnetti is prohibited by their contact with VAG from selling those components to 3rd parties. The OEM...
