Welded Diff. VS. LSD Pros and Cons??

If you have the money get a 1.5 way or if you dont get a Vlsd. The 1.5 is probably the best road race diff(even better than helical) and the Vlsd is like the bullshit compromise you have to make if you dont want a locked diff and you dont have money foir a 1.5 clutch type. The clutch diff also requires maintenance and will need rebuilding over time, and if you want it to work perfectly you might want to re-arrange the clutches for a different lock percentage which is a lot of work if the LSD is already installed, but probably unnecessary unless you're anal about everything.

Additionally, would higher-grip rear tires on a welded diff increase off-throttle understeer?

thanks for the help.

Yes .

Depends on the car setup. In a really stiff, well setup, high grip car i would take a welded diff and drive it F1 style. Slow in and accelerate all the way through, but you'd also need horsepower to make it work correctly. Otherwise I would take an open diff.



Another random thought for road racing

The ratio you choose(2-way, 1.5 way or 1 way) for your lsd should match the car in question. Driving the car with an open diff is the best way to figure it out.

For example let's say i have an S13 and it's set up for road racing. I've already set up the suspension and tire stagger perfectly so it doesn't understeer on turn-in and I can make it oversteer just by steering. Then the diff for me is the 1.5 way. It will probably help stop the extra oversteer on turn-in unless i'm trail-braking and i want to oversteer a little and it will lock strong and pull me out of the the apex when i get on the throttle.

If my car/driving style is hopeless understeer on turn-in, then i would stay far away from anything that has locking on decel, cause it will make it worse.

If I was setting up a car for auto-x, it would get a 1-way diff for easy rotation at lower speeds.

A car for drift, i'd use a 2way for straightening out the rear end mid drift by getting off the throttle.
