Hy,
anyone can say me how much i must change rear end pinion to come to the correct streetable operation angle.

Found a few sites on web where explain everything about pinion drive angles but i´m not sure if understand everything correct because...my lack of English.I´m a little confused and maybe it´s a stupid question but i wanted to be 100% sure, so please take a look at the pic and let me know.(but speak slowly for euro guys )


Current Set up= Rear 3°up and Trans 3,5°down = +0,5° correct?

I would need -2to3° negative drive working angles correct?

So how much and in which direction (up-down) must i change the rear.

Must i subtract the rear measurements from the trans measurements or contrariwise?



Thanks for help.

 

forgot the pic...

 

What are you doing to need to change anything? Have you raised or lowered the car a bunch? What you are showing is drive line angle. Unless you are drag racing you don't need to be messing with the pinion angle either. Explain a little more of what you are trying to do.

 

I don´t want to race or change height for now,only want to set the pinion angle correct to prevent vibration noise.

Can i stay with this angles?
