Thinking about purchasing a diff for the Fiesta ST, as when your going round a roundabout you get severe inside wheelspin and it loses you so much grip, hoping this will help...

My question is, how hard is it to fit a diff to a gearbox that doesnt have a limited slip? ie

How much would someone charge to fit a diff to a gearbox? is it really expensive?

 

I reckon a quaife ATB diff would help if you were doing track days, but TBH with 150bhp it cant spin the wheels up that much in a corner.

My ST170 doesnt suffer from spinning the inside wheel when applying power in a corner (with traction control off)

it does suffer from excessive understeer but not caused by power delivery, just caused from reaching max corner speed from the grip of the front tyres. Are you sure you not mixing the 2 up

 

Im positive im not mixing the two up...

Plus you didnt answer the question fucker


Trust me the wee bastard thing needs a diff... badly.

you mustnt drive it hard enuf then

 

Trust me, after a 30+ laps pf Brands Hatch i was driving it hard enough Maybe the Fiesta is shit around corners

I dunno how hard to fit, im not a fucking a mechanic! i pay someone to do, what i know i cant
