C4 Bolt In Solid Rear - Reviews?
There's been several threads lately about rear end reliability. I was wondering how those with the bolt-in solid rear ends were doing. It's been a couple of years since there was a lot of talk about them. I believe the price was around 3.5-5k. If I remember correctly there were two options at the time Ski_dwn_it and Racecraft.
Can anyone thats been running one of these give us a review or update. How are they holding up? What 60' times are you getting? Regrets? How do they handle on the street or road course compared to the IRS? etc..

I was one of the first ones Leo (now Carroll's Rod & Racecraft) did. No problems, over 100 runs, always hooks, 1.35 60'

I dont know about others but I recall something about the Ruby leaving puddles of gear oil in the driveway. The owner was really ticked. A search would probably find it.

Be even better if you show off your 5" inch exhaust with a bigger wheelstand on the back bumper.....
9310 Nickel Gearsets last longer against Gear tooth breakage in a 8-7/8" inch Chevy 12-bolt and a full Billet steel race spool used.
I set racing rears to a tolerance of + or - .0002" or 2/10,000 of an inch.
Helps with gearset longevity.
Have other tricks I use too.
For what ever reason , Ford 8.8 inch rears do not need 9310 Nickel Gearsets.
Have built several for 8 second cars and One 8.8" for a 7-second 1/4 mile drag car.
Housings are super stiff and don't deflect easily under high torque loads like a Dana 60 housings have extreme torsional rigidity likewise.
No one has ever broke one of my racing rearends.
I build them according to racing needs.
Some have several thousand full power passes on them and going strong yet 10 years later.
One guy ran 60 foot times of 1.2 - 1.1.
He pulled a 1.0 one day on my the 12-bolt rear I built for him.

Aaron, look at this link, post 21, and you will see pictures of the car. http://forums.corvetteforum.com/drag...le-guys-2.html
BTW, it was my understanding, the builder actually did the install as well.

what did he actually have to re-engineer?
I think some specific information on what was not right is needed.
This job is not a plug and play and I would expect some issues if I were doing it.
If your not racing a lot I would stick with the irs set-up,this is not for a street car IMHO.

I have read many of the old threads in the past.
Spent my 1st year here on C4 reading quietly.
Straight axle still works best for drag racing.
C4 independent rear has amazing Anti- Squat capabilities engineered into the suspension stock.
With some tweaking you can achieve over 100 % Anti- Squat pretty easily.
But you will break parts no matter what with the Aluminum C4 Dana 44 rear if you hook hard enough or have enough torque and Horsepower that modern engine builds and bolt on Power adders can deliver.
Tremendous Anti- Squat for an independent rear is why our C4's do not wheel hop where C5's & C6's do stock.
Different engineering teams in different eras with unique set goals is my theory why.
The father of our C4 cars was an Avid Porsche fan and part time racer likewise.
C4's are not done.
Just slow stock compared to modern cars because lack of available Torque & HP from the old tech engine.

If you ever get your 84 Vette on the rear bumper Willie,
Next time hang a Large American Flag on the undercarriage.
then have someone snap photos a short distance from the starting line.
I have a midwest published paper flier magazine called GEARHEAD NEWS that has a cover shot photo of a 3rd generation Camaro doing a back bumper wheelstand.
That guy hung a Huge American Flag on the bottom of his Camaro.
Made for an Awesome Cover Photo.
That was right after 9/11.
