What is causing my tire to spin the whole way down? Particularly the left rear tire? The tires are BRAND NEW 315/35/17 Nitto 555r DRs. I am launching at 3k in the first vid after burnout, and idle in the 2nd vid no burnout. Car has adj BMR LCAs, SFC, stock suspension otherwise. I am fairly sure my shocks are blown and thus might be the cause of this but I wanted to get some others opinion before I go and replace the shocks.

stock 10 bolt? did you get beat by that mustang?

 

stock 10 bolt

 

I would have to guess its the 10 bolt.

 

differential in the stock 10 bolt is probably letting go. buy a 9". i have a 12 bolt...unless you need a 12 bolt with 4.10's.

 

the rear is fugged up....

 

what do you have the tire pressure set at?

 

Check your tire pressure, ditch the 10 bolt

 

This is your main problem. You waisted approximatly $400 on two tires.

Being stick you should generaly be on a bias unless you are running a class.

And nittos are barely half a step over stock street tires. A few people have good luck with them but in general they are a compleat waist of time.

 

nitto's are a ricers way of having "race tires". they look good but not beneficial.

the stock 10 bolt is a total pile of junk, the clutches and springs in the stock posi unit arent strong enough to hold and thus your single tire fire.

go with the 9 inch, its easier and faster to swap gears in the 9 inch...one of the few good things ford has engineered lol

 

most of time you can find a fabricator/welder at the local strip that could probly help... atleast u can here in concord

 

you sure its not rubbing under wot?

 

I've seen this guy race his old TA with the same mods tires and stock 10 bolt and cut 1.8's without smoking down the entire track. My car also has even older nittos and a stock 10 bolt and does not have this problem.

nah dude its ur 10bolt go spend $2,500 on what could be a really simple problem...

How does the inside sidewall of your rear driverside tire look?

 

I ran at 23 psi or so

This is actually possible, I'll check out the tire

I daily these so that's part why I got em. In my old ta with same mods I cut much better 60s and didn't spin so I know it's not the tire.

 

Never seen this before I would lower tire pressure to 18-19 psi try again and if still does it check your rear shocks might have more pressure leaning to one side causing this.

 

tire or rim is rubbing, bad posi, could even be a small leak of fluid of some kind but i doubt that. Check the inside of the rim and tire and look for marks. See how much clearance there is between every thing and see which is the closest to the tire.

 

Quite a few things worth checking before buying new parts. If it does turn out to be the rearend please shoot Me a pm to get a quote for the special on S
60's CRP is having.

 

If that tire was spinning you would hear the RPM fluctuating all the way down the track. You have something rubbing on your left rear tire. Stick your head in there and see what it is
