Wheel Hop Vs. Rear Differential
 

Went to the drag strip last night and the diff. decided to go. With street tires, diff. brace and solid mounts it must have become the weakest link. If anyone has a complete rear differential (MT) I am in the market. I plan to go back stock and give up on the hard launches. All this and after I just rebuilt the motor, boy you have got to love these cars. Makes me want to go back to my first vehicle, '74 Rotary Pickup with side housing bridge port.

if you're drag racing you need an upgraded LSD, upgraded gears and a differential brace, once you get out of the 13s. You're lucky if you made more than 2 passes on the stock setup.

/\ lol

ok.....
what you realy need is to not wheel hop the car

With the amount of miles (177k) on your chassis/diff, how can you be surprised?

Look into getting an S4 TII diff, much stouter than the oem torsen. The pumpkin installs right into the housing. I have been running one for a number of months now and love it. No clanking, clunking like with the cusco, kaaz, etc.

I have a stock 4:10 rear (100k miles on it) Don't know what they sell for.
I'm in eastern Pa. and can drive half way to where you are in Md.
PM me.

That is a..... very broken diff.

Your drag racing a car that wasnt designed for hard, repeated launching.

Your problem is the exact reason I refuse to launch my car on the rare trip to the strip. Just accept the 3 sec 60ft times or upgrade :)

Eh I've made a ton of passes with a stock diff, just had a diff brace really aside from a ppf and suspension.

Capitol I assume? I got there and my friends told me an FD had gotten taken off maybe 20 minutes before I got there... What RPM were you launching at? It was cold as piss I'm surprised you could get enough traction to really break the rear end.

My advice is do the same thing Rich suggested - TII diff.

I have never seen seen a diff explode like that. WoW!

It also kind hard to practice launching tracktion on the street is quite different from the strip. I broken to many cars to ever go back unless I win the lotto.

If you refuse to launch, then what is the point of going to the strip to begin with?? The 60ft is going to make that low ET.

Wheel hop is what destroys things. Ray wilson was running mid-high 10's with a STOCK diff, STOCK axles, STOCK gears in his street FD.

Slip the clutch off the line, dropping the clutch on anything less than wrinklewalls will probably get wheelhop. My stock 4.10 and axels have many mid 11 sec passes and 120k+ of abuse. I just put my t2/3.90 diff back in the car in preperation for some 10's.

This is one of the reasons I never launch my car. I bet the people after you weren't happy about the differential oil that spilled. ;)
