Mardave V12 Diff
 

Quick questions.

Are they worthwhile for circuit racing?

What benefits if any do they give?

yep up the corner speed:)

Thats the same question i was going to ask, then heard that they make no difference...but still might try one anyway

Well I've ordered one for my circuit racer along with some other bits. Will see how it runs on tuesday!! :thumbsup:

from what i have heard, they are only abit better on tighter corners

Having tried both in my circuit car, save your money makes no difference what so ever.

I think the diff makes a big difference. With the solid axle the car is always prone to waving the back end about when you put the power on coming out of a corner. The diff calms this down a lot. I find it tends to make the car understeer, I'm guessing it gives the rear more grip so a change in tyre setup and driving style is required.

Takes a bit of time to get the diff set right and not binding.

i find it a big advantage-
tends to make it turn in sharper
less wear on rear tyres due to them not fighting each other for grip

only downside is more likely to wheel spin when accelerating hard so i just run a softer tyre
