Experience from who, using theirs or ours. I don't take any disrespect from what you said, but I know what goes into ours and I would put them up against any bodies. There is nobody that has built these that has not had one blow up, but neither one of us also know exactly what is being done with them either. I have had all kinds of stories given to me that end up only being about 10% of what really happened. We have allot of diffs in Professional race cars that they buy from us. I have no doubt that nobody goes through what we do in prepping these diffs.

 

Speaking of which, have you guys or anyone else considered a redesign of the case? Maybe another material? From the failure I had and the others I have heard about they like to Crack on the back and the stress Crack propagates through the shell and sometimes takes out other components with it. I am sure that hard launches over time slowly plastically deform the stress concentrations and eventually it catastrophically fails.

 

My experience with Zip has always been very good.

I would hate to see how much a case would cost if a new one was designed by a vendor.
A case requires a great deal of tooling. Finspeed quit making an improved Z06 cooler becasue they could not sell enough of them. If you want a stronger case, take a new one to a good shop and they could make you a billet one. The only problem is that it will cost more than the car.

 

Hence why I asked Zip. I can design and build a one off billet case I have the background and the access to a prototype machinist however if they create a production run it would be cheaper and easier than a one run part.

 

Sounds like you have a solution! Enjoy.

 

My experience is with RPM and I guess most with C6 knowledge know their equipment is in the fastest C6 Corvette on the planet. I'm sure your stuff is good no matter what.

 

need a like button!

 

I've been a Plumbing/HVAC business owner for 36 years and seen a lot of companies but RPM is one like few others....run like fine clockwork!

 

That's understandable, but there is always someone better and someone faster. I don't claim us to be the best, I would rather Humble ourselves but I know what we put into them which is the only reason I asked. As far as fastest drag car, Yes I believe they built the diff for that very fast Orange C6. Our diff won was in the car that won the national title in SCCA T1. I do not doubt they build a good diff though, we have a twin turbo ZO6 with one of their automatics in it.

 

The problem always comes back to money. To do that housing you are probably talking $300k if it is made here in the states and I don't make anything overseas so that would not be an option. How many could you possibly sell? You would have to sell 300 @ $1000 to pay for the tooling not including what it would cost for me to actually purchase the housing. I just don't think it would be feasible which is why nobody else has done it either. We looked into making the ZO6 Ring and Pinion and it was 250k with agreement if we didn't sell enough in the first year we would lose the tooling and the manufacture could sell them to anyone. Well Richmond is not in business anymore but that was from them so we dropped it. At the end of the day you can't lose money doing it. We spend everyday fighting internet companies who are selling products that they are not licensed for but they advertise at almost cost. There is not enough profit margin anymore to develop new parts like what you are asking. I would love to, but it's just not there. I hate to sound like a broken record, but when everyone buys on price which I can't blame you. If a company has prices on parts that are really cheap and they don't stock any of it, that is a good indication that is one of the companies I am talking about. They don't develop anything, instead they use the advertising that companies like ourselves put out and then the cut the price sometimes below cost because it drives you to their website. It cost allot of money to put items on the shelf and then not actually design and R&D parts, if I am not making money on the items I am selling then I can't develop new parts. It is something that all the bigger companies are dealing with right now. The problem is that while is seems like we are charging too much we barely make much money on the item, but when a company advertised something for almost cost that they don't stock, we have a price matching policy and we end up matching for customer service, but we ultimately lose money. That doesn't pay for things like stronger diff parts to be developed. I didn't mean to turn this into something big, but that's the truth of it and why those parts are not being developed. So next time anyone that see's this is buying based on the lowest price, check the website and see what there terms are. If they don't refund, or stock or even have an address, then buy from someone who does and all this in time will fix itself.
