I searched and couldn't find a thread for it. I've notice my car only spins on the right wheel when i burn out. is there any type of gears or something i can get to make it spin both of them? JW cuz its kind of annoying.

 

limited slip or posi gears would be a start.

 

easiest way is to get a whole rear end that has it already and replace it, faster, cheaper and less frustrating. or a powertrax. both equal installation IMHO.

 

The Limited Slip carrier is correct, but no such thing as "posi gears".

 

I was thinking posi rear ends, nvm that, limited slip is the best bet if your going to use your original rear end.

 

err, Positraction is a type of limited slip differential. You can't have a posi or LSD as posi is an LSD.

I agree that swapping out the whole rear axle for an LSD rear would be easiest.

 

by swapping out my rear end with lets say a dana 44 wil it benefit my how fast my car goes or will it just enable both tires to turn?

 

a dana 44 is not any stronger than the one you have now.

as said before a different rearend would be best.
and try to get one from a newer third gen, they were stronger.

the gear ratio will make you faster and slower. lower gear 3.42, 3.77 you will get a stronger feeling from a standstill and get to cruising speed faster. But your rpms go up and mpg suck. also top speed is lowered greatly. the reverse happens with a higher gear (lower number)

i would suggest not going above 3.42 if you want some economy still.

 

I swapped my 2.73 open rear end (open is the kind of differential that you have now just in case you were wondering) for a 3.27 limited slip rear end (both wheels spin). Cost $200 off of the boards here. Favorite thing ive done to my car so far. Picked up over a half second in the quarter. Also upgraded to 1LE rear discs from drums at the time. If you change your gear ratio you will have to change the speedo gears in your tranny for your speedometer to work correctly. IIRC most if not all 89's were mechanical speedo's not, electronic. If you swap from drums to discs at the same time it will cost significantly more than just swapping the rear, but its a good upgrade.

 

If you dont care about tires buy a mini spool for the 10bolt axel out of summit or jegs ther like $75 and it will make it spin both tires all the time.. its also pritty easy to put in if you have a good idea of what you are doing.
then ur car will be burnin both off..

 

FYI....the Limited Slip rear was to improve traction in poor weather condition so both wheels would get traction. It wa not ment to have both tires burning rubber like some young uniformed people think. One sign of this lack of knowledge is when they use the term "POSI".

 

so, lets say, you change you rear end from a 3.42 to 2.73, how do you change/ ajust your speedo gears

 

"IIRC most if not all 89's were mechanical speedo's not, electronic." - I am no F-Body pro but, I know that my T-5 89 Formula has an electronic unit. I believe that I have read even some earlier years (maybe 87+ ?? I dunno) had electronic VSS setups. Whereas, I have heard the inverse for the Camaro, having a mechanical setup in those years. To tell you the truth, I would prefer the mechanical, it would be more flexible (for me).

My opinion on the mini/full spool setup would be that it is not a Street-worthy option as it is somewhat unsafe. (Losing rear traction in corners) Although, for a straight-line, it is much to be desired.

As for the concern of only spinning one tire, are you concerned that you are losing traction, or do you wish to lose traction to the whole rear of the vehicle?? hehe Because, there maybe be cheaper alternatives to get more traction. I have the factory LSD and with a worn stock suspension, and it isn't exactly traction I am getting out of it.

Well I'd like more traction but i just find it kinda annoying that only one tire is propelling the car and at mainly just a preference but i would be a plus if i can make my car faster with it

 

my 89 camaro 700r4 had mechanical. not sure if pontiacs were different, or if manuals were different, but seeing as you have a manual pontiac and pv9685's manual pontiac was electronic, i'd say your's probally is too. I'm not sure how you fix the speedo on an electronically controlled car. I know on the new ones its all in the computer, but third gens didnt have computer controlled trannys, so not sure on the difference.

To make the car faster put in a lower (numerically higher) rear end ratio. 3.42 or 3.23 seem to be very popular route to keep RPM's down on the highway while providing a quicker get up and go then you're probally used to.

 

you can get a kit that allows you to adjust the pulses from the VSS so it can adjust for the different gears.

My '89 TPI car is not mechanical.

 

every1 else has the idea... ur diff is an open differntial and posi-trak (lsd) will give u a better launch and more traction. and go easy on the burnouts! our 10 bolts are pretty weak and thats really hard on the entire diff as well as brakes and tires!
