Dear Fbody friends,
I just picked up my racecar from the shop here in Atlanta, they did a GREAT job and put the whole rear end back together for me with the NEW posi unit that I bought here on the board from LS1RAFTRACER.

They suggested that I give the rear end 200 miles to 'break in the new bearings' and seals. So.. My car is NOT street legal, i'm curious HOW DO I DO THAT?

Seriously, I asked these guys at the shop and they said it needed AT A MINIMUM 2 HEAT CYCLES to completely get the break in period.

So, do I run the next 2 events in Atlanta Solo2 at 'street pace'? OR drive around the neighborhood 200 times?

do you have any other ideas? OR do you think they are being silly. I am worried about the gears seating properly so I guess I'm listening to the guys that know. What do you guys in the know think?

Get some jack stands and lift the rear off the ground. Chalk the front tires as best possible. Run the car at speed 60-90 until you build heat in the rear end.

I know its not the safest thing to do, but good stands and good chalks will minimize chances of a problem.

One of my buddies had to do this to track down a vibration he had in the driveline at 200mph. Since you cant get out on the highways and run 200mph until the road is closed for an event it makes it tough to do. He used the above method and one of his crew went UNDER THE CAR (IMG:http://www.frrax.com/rrforum/style_emoticons/default/blink.gif) with everything spinning at 200mph (IMG:http://www.frrax.com/rrforum/style_emoticons/default/blink.gif) (IMG:http://www.frrax.com/rrforum/style_emoticons/default/blink.gif) . They were able to find the problem and fix it. Not the brightest thing in the world but it worked. At 60-90 it wont be bad at all. LG does it quite often in the pits prior to taking it on the track just to check everything out.
