Diff problem
Dutchman - 10/9/07 at 10:30 PM

I'm using Lada diff it has 4.3 ratio and the gear box is

1st 3.75
2nd 2.30
3rd 1.49
4th 1

and motor is from fiat coupe 2.0L 16v 155bhp
when i start it full throttle it slip till the mid 3rd gear ... on 17inch 225/45 PZero tires ...

some ideas how to make LSD or some other advice ...

Learn to drift?

Sorry, don't really have a good answer.

don't know if an LSD would really help. I've got one on my tin top, and i'd rather do without sometimes. when it rains all it does is make both back wheels spin and there's no grip at all. any different axles available to you? did Lada have any different axle ratios?

edit: or don't pull away with full throttle?

there is 3.9 diff from Niva but I don;t know will it help

Angle top links to use torque reaction to push axle down.
You can use an esky diff with the lada axles and housing for more ratios, will require a 3mm spacer made up for between the housing and head.
Have the spider gears shimmed up to load the side gears more, creates resistance for the spider gears to turn, el-cheapo LSD but works well on such a light car.

The 3.9 will definfately help a lot.
