View Full Version : Next step up over 4.10's with stock rear???

07-02-2002, 02:08 PM
I see 4.10's for sale and I know a little grinding is required with the $99 Torsen dealie from SLP... but whats the next step up?

Will they work with the torsen unit? What is required to make them work?

I wouldn't mind a cheap spool or locker of some sort. My car is no where near stock anyway so I'm not worried about driveability.

Don't waste money "upgrading" the stock rear. As you go up in gear ratios, the gear sets get weaker and will break easier. This is because the pinion gets smaller and smaller.

4.30s would be the next step. I'd rather put that money into a 12-bolt though.

I have a V6 so I don't have to worry as much about breaking the gears. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I'm shooting for 12's NA. Gear will definately help.

How much work is required to fit the 4.30's on the torsen LSD?

Would 4.30's be capable of handling a 1.6 60'? My car doesn't hit THAT hard but it does hit.

Perhaps there is a cheaper carrier method to fit 4.10's and 4.30's? I don't mind a spool/locker setup... ???

I haven't seen 4.30s for the 7.5 rear. Only 4.56s <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Ok.. Since I only plan to spin the motor to 6500 or so I'm gonna stick with 4.10's..

Thanks for the help once again!
