focus ST 225 upgrade

[BogST3]

Evening all,

Currently I Have a mk2 st and the clutch has gone on it, it is a 55 plate car. I have priced up a new ST clutch and a new RS clutch, but i was told the RS clutch won't fit, is there any truth in this matter?

I'm hoping to get the car to dream science and have an inter cooler fitted and get the mod x remap put on the car too.

basically i'm just looking for a bit of advice as I dont want to gamble buying the clutch kit if it won't fit my car>

Thanks,

Dan

Go RS. Fits straight in. ST clutches in earlier cars are hit and miss. My St 2007 MY has an RS clutch. Bit more of a switch on off than the ST clutch was, mainly because of the stiffer clutch plate.

Thanks for the quick reply? does the RS one come with the torsion diff included or is that an additional fitment?

Diffs in the gearbox, nothing to do with the clutch. You can fit a LSD while the box is out, which would save labour in taking it out again, but to fit the diff the gearbox needs splitting and stripping, so is quite expensive in diff and labour time. I'm running 300 bhp on an open diff and its not 'that' bad. Would make it better to fit, but its not uncontrollable.

what will the standard ST clutch hold upto bhp wise? if it's not a strong clutch it makes sense to change it while it's knackered

Pass....... its a lottery. Mate had a car running over 300 bhp on the standard clutch at 100k miles (06 plate). I had , to begin with, 260 bhp ( mountune MP260) at 40k miles and couldn't cope (07 plate). Best to just fit the RS , its the same price or thereabouts and the recommended upgrade.

Wifes old mk2 ST hated going stage2 and the clutch soon died.

RS item slotted in and no worries.

My mk2 Focus RS runs 400lb/ft on the standard clutch. So it will cope.

My old ST (2007 '07') just had a Dreamscience remap on the standard clutch & it was fine, no issues.
