Just got the Cusco 1.5 rs at 80% lock installed with a set of hotchkis sway bars.

What a world of difference. I feel these two mods a lone are worth around 2 to 3 seconds for me on a 60 sec course. Always had a bad problem with putting power down at corner exit but the Cusco has remedied that pretty well

Not quite on par with awd cars of course. Figure once I get some decent tires next year I should be competitive for ftd at my local autox

Highly recommend these two mods.

Any of you guys have to change your driving style when you got the lsd installed? More point and shoot vs momentum? I find the lsd wants to straighten the car out.

 

LSD, of yes, been saying this for a while. Swaybars help, but really not that much.

 

Before with my old worn out vlsd every time I gave it anything over a quarter throttle coming out of turns would kick the tail out. Just from the limited testing I have done I can almost flat foot it at the last 3rd of a turn and let the lsd straighten the car out. Granted I'm stock power wise. I think people really do underestimate what a good lsd can do.

The sways helped make the car change direction quicker. My local autox tends to be slalom heavy so this will help. Before the body roll just really unsettled the car.

If I had to pick one or the other, lsd hands down

 

I can totally agree with this. I went from the open diff to the OEM VLSD with Whiteline inserts and IP diff brace, and installed Nismo sways with new tires and the car is in another world!

The car used to be so prone to understeer, than the rear snapping out. Now it just hunches down as I power through turns. Even when it oversteers I feel like it is so controllable now.

 

OEM to VLSD feels like a 20% improvement compared to a real diff like an OS unit. I've driven my cars back to back on all 3 , the VLSD improvement is nothing like a real diff

 

With the Cusco (or any good diff) the locking and unlocking effects on-and-off throttle will be much more pronounced.

When on-throttle while turning (diff locked) the understeer effect will be very noticeable, as you are experiencing...the car will want to veer away from the apex. Conversely when you feather off the throttle and let the diff unlock the nose will tend to veer into the turn.

This throttle steer effect combined with the added grip afforded by the Cusco will definitely lend to a slight modification in driving style.

 

Yea, it'll take some getting used to but I like it.

 

This is true. The Cusco is night and day compared to the stock vlsd.
