And no, unfortunately no ownership interest. As you know in the past I have joked about a job at GMR....but if that where to ever happen I guess I would have to heavily work on my people skills as I am not very popular with some (never my intention). I think I will turn a new leaf today (thanks Ron and all the small people that made it possible ) and play better with others. So come on and give me another chance

I think you misread my post about experience rather than opinions.... Read it again with a little less bias on your part and see if you don't come away with a different 'opinion'.

You'll find LAT G quite different than Pro Touring - discussions are civil - informed - and usually come from experience rather than just "my opinion 'cause I read somewhere in the internet". This is no place for flamers - they get run out of here in one day - or one post. I've read 1000's of posts on here and 99.9% are just great general discussions without "tones" or "flames" or anything like that.

It's a fixed sealed bearing hub that is bolted to the axle housing. The axle is affixed with a nut. It's not really a floating axle like a conventional floater.

We are a great group of guys, we just don't take any crap. You shoudl come out to the pro touring events. They are a blast.

Todd you are correct in your statement about the ZR1 hub, the axle IS bolted to the hub cap,it is not the same set up as a factory Corvette which uses the large 32mm nut. It is simply a socket head cap screw to help more with the install of the axle. a normal floater uses a cap to retain the axle basically the same principal. The Speedtech/Chicane set up also uses in inner axle seal so the tubes are Dry, no gear oil in the axle tubes. makes things alot cleaner when servicing. also the Hub is a sealed unit as you would know so no maintaince required there either.
So it really is Technically not a floating avle BUT due to the fact that the Wheel Mounting Surface does not move with the axle and is fixed there is no caliper knock back issues.

Blake,

Be very cautious with the axle tube seals. We lost a 3rd member in the race car using these. We tried several brands of seal and even a couple different types of axles. All sized properly, but in the end all they ended up doing was trapping the lube in the tube once it got past the seal and didn't allow it to get back into the sump. I had multiple conversations with people and found a lot of similar feed back. Obviously since my application was circle track the right axle tube was the culprit. I'm not sure you will see this in the Pro-Touring/Track Day venue, but it is worth looking into. I would hate to see you deal with come backs over burned up gear sets! In the end we just ran a slightly higher oil level in the rear and made sure we had good o-rings on the hub seals. Never had an issue after that. (Obviously this was a standard design floater) All in all it was about a $2K lesson between broken parts and test pieces trying to solve the problem. Hope this helps some.

good feed back. this is not something i had heard of. but i have to now check with Speedway Engineering on this. i would think that Kenny know if the NASCAR guys are having problems or not. he told me yesterday they had something like 40 rear ends to build for Daytona

i will call and post up the response. it is an easy thing to delete if it may cause a problem.

stay tuned

Sounds good, and I will be the first to respect that since I am the same way. I will be out and about soon, thanks for the kind invite and look forward to meeting you personally as we may be more alike then we would probably admit currently. Oh, and sorry about the banana seat comment!

They should certainly be able to help. We tried seals from Allstar (Motorstate), Afco, and Speedway. We also tried standard floater axles as well as GN axles. We also tried GN Seals with standard axles thinking they would be tighter, but couldn't put it together. Obviously gun drilled won't work . I'll be anxious to hear your feedback. It would definitely be the way to go if you can be successful!

Spoke to Speedway they Normally do run a inner axle seal including snap rings on both sides of the seal on all the NASCAR housings. That being said he has not seen any failures since 1993 when they changed to a different type of diaphram seal. BUT did say that is would be possible if the housing was bent or "rubbed" as the seal is quite delicate and also can be damaged during assembly if the axles being used do not have a large enough taper on them. that is the official answer.
Also the housing has axle seals at the housing ends. so the inner would not be required.
