Concentric Hub and Wheel Adapters

I upgraded the brakes on my 1986 Corvette, which requires a larger wheel. using the concentric hub and wheel adapters will allow me to use a later year corvette wheels. If I go with the concentric hub and wheel adapters how will it affect the Tie Rods, wheel bearings and other suspension components?
My end goal is to run the Texas Mile. Here is a link to the place that makes them http://www.motorsport-tech.com/wheel_adapters.html
Thanks for your assistance.

Welcome to the forum Steve!

I can't help you with the your question, but I would like to know more about your goals for the Texas Mile. Is that in the near future or out there a several years? I've always wanted to to Bonneville and the Texas Mile would be a logical first step.

Grumpy will most like be able to help you with the wheel adapters, so check back in a few hours. Hopefully the holiday won't get in the way of getting your answer.

I had to use those adapters on my 1985 corvette when I adapted the wheels from a 1995 corvette to 17" rims ,I purchased ,and upgraded my brakes so I have some experience. you should not see any problems, your effectively making the wheel base a bit wider and in theory that puts a bit more stress on the suspension, but Ive been running about 470hp/510 ft lbs thru my 1985 with occasional use of a 200 hp shot of nitrous and while transmissions , differentials,and u-joints and half shafts have failed the wheel adapters , bigger brakes and slightly offset larger rims with bigger 17" tires have had zero problems.
why not call the manufacturer of those spacer adapters and talk to the tech guys for their input, theres bound to be both carefully machined adapters and cheap zinc castings available so you obviously need to select adapters made from top quality materials, you obviously don,t want to trust your butt to cheap zinc cast spacers but I,m fairly sure durable parts are available

Spoke to Steve earlier on the phone Grumpy.
200- 240 MPH speed at Maxton.
The custom 1 off Aeromotive Stealth 340 X2 ZR-1 Fuel pump I built for Steve's Racecar

Concerned with Stress failure limit of Hub a Centric Wheel adapters.
Lost front or rear wheel at 200 + a disaster.

Steve is venturing to New C4 Corvette Racing Territory
 
750-800 HP 434 Ci SBC with 15 degree heads.
2 inch primary 3-1/2 " collector. Custom 1 off Dawson headers.
His Vette going Twin turbo. 2000+ HP.
Think Wheel adapters hold up ????

If fail.......

Yes I thought the same Grumpy....
I told Steve that We need a real Mechanical Engineers input.
The best I know....Grumpy.
How this thread started.
Steve is Capable of Handling 220-240.
Custom Hubs must be machined from scratch.
At least A11 Tool steel .
Have to draw prints again.
Run idea by Mopar Bob......Thought It was impossible last Race project made rogether....

First step is to run the Texas Mile sometime next year naturally aspirated just to get a feel for wide out driving. Hoping to break 180 MPH, Then start to change over to building the turbo motor, I have all the engine parts for the motor except the valve train and cam, been planning / dreaming about this for several years.

Thanks Grumpy, that's good news to hear, I always like to get an outside opinion‎s from persons that has /had experience. Another question Should I change the OEM lugs before I attach the adapter? The rear have never been changed, the fronts were changed about 15 years ago, car has not been driven in about 7 years.
