i bought lakewood upper and lower control arms and put them in last night... is it possible that i over tighten them. the car in the rear feels way to tight and is stiff as hell. i also put 50/50 lakewood shocks and the car don't move.. should i try loosen the bolt or this is normal?

[nasty92LX]

i have southside upper and lowers with lakewood 50/50 shocks and mine is stiff as shit. Thats how it is.

[88stangGT]

i thought since u put the 50/50 in it would like drop down when you launch the car.isn't that what you want the back to drop down and the front to come up to hook better?????

[ujslost]

did you tighten all the hardware before you loaded the suspension? if so jack it up and loosen everything again and let the car down and tighten again with weight of car on suspension

[nasty92LX]

my car dead hooks. It might not fee like the bac will go down any but when your car leaves it will squat.

My dads car is the same way and he goes 7.80s on drag radials. With a 1.21 60ft.

Stock shocks are a 50/50 ratio. No you don't want the rear to squat. When a Mustang squats it is unloading the rear tires and wasting horsepower.

Rebuild the stock rear end and call it a day. Or upgrade it using the Cobra carbon fiber clutch packs. Ryan did a detailed write up on rebuilding the stock traction lock. Trac-Lok rebuild how to.

Maybe Ryan will chime in. I don't know a lot about the Cobra rear ends.

[ryans88gt]

yes, you can use the 31 spline cobra diff. For drag racing, you're not putting nearly as much stress on the diff as you do taking corners under power.

My stock unit with 4 normal clutches is holding up to 500 hp at the wheels. The carbon fiber clutches are designed to hold upto 500 hp, so if you pack 4 of them, I would say you are more likely to break an axle than burn up the diff...maybe 750 hp. More than that and you might want to start thinking about a spool and 33s anyway.

Detroit True Track.....Hey Ryan how about you get your 750 ponies and test the theory of the clutches for us all....I just want to see your car have that power then I am buying a plane ticket to get a ride in your car...lol

[91cobra5.0]

how much did the control arms cost you?

It just a quick nitrous jet change away, but I like my engine in uno piece.

[88stangGT]

bought them for 200 of my friend he went a diffrent route.... ok so i should be fine with the 31 splines and the cobra rear i have a stock motor for now but im puting a turbo on it over the winter...

[97SnakeBite]

your upper arms might be sticking...this is a known problem when changing these..if i was you i would put my stock uppers back on cause they dont bind...thats the only part of the susp ford did right...
