With my 283mm discs I believe I only needed a washer as a spacer
I may try a set of 283mm discs then... When you get them fitted the difference is unbelievable ,when i upgraded the rears from 252 solids it totaly transformed the braking .

You dont need to machine 283mm discs down, all you need to do is to file some metal off the caliper bracket that holds the caliper to the hub. The Escort Cossie calipers take a 278mm disc and you need to shave off enough metal to allow it to take a 283mm disc. However we are only talking about taking off 5mm total, which is 2.5mm to each side of the caliper carrier.
Dont buy 278mm Escort cossie discs either as the offset is all wrong. You need front discs from a RWD Sierra Cosworth discs and pads.
Ive done this conversion twice - once going from a 240mm disc (Cobra Kit Car) and the other time going from a 260mm disc (Griff 500 brakes). In both cases all Ive needed to do to centralise the caliper bracket was to put a 1mm washer between the hub and the bracket.
Hope this helps.

Hi, planning on doing this conversion have the calipers. Disks i can get but what pads are people using the mondeo st200 ones or do the sierra cosworth fit. The reason i ask there is a cosworth 500 kit containing both pads and disks which seem good value
I have THE EBC Yellow stuff part numbers you could cross reference ..These fit my 887 887 calipers
DP4956R
The later rear setup DP4617R with 272 vented.
Yellow stuff pads are great for fast road use and the odd trackday.
So can someone confirm from what car the rear later calipers and discs come from ..
If anyone upgades from the resr solid 252`s the S TVR owners will buy the hubs ,calipers and discs because it an easy upgrade for them to go from drums to discs.

Hello from far !
I remember 3-4 months ago here was one topic with the same target that someone made a conversion by one chimi with a 4 piston caliper and 283mm disc of the Sierra Cosworth RS500. Somebody remember over this topic it was with pictures?!
It is a nice project.

I just had the 5 stud hub conversion done on my Chim and i'm very pleased with my Spiders.
The problem is one of my front discs is warped (juddering under breaking) and I wasn't going to do the Tuscan/ AP upgrade until winter.
Does anyone know of any replacement front discs (240mm @ 5x114.3) preferably drilled and grooved?
I've found a link that shows other cars with the Tuscan PCD (Honda Accord, Civic, Mazda 3, 200SX, etc) and there are 240mm discs listed for those cars on eBay, though i'm assuming there are other dimensions to consider, such as profile and bore diameter etc?
thx

I may try a set of 283mm discs then... Still havnt fitted the ones you sent a year or 2 ago! oops!
Whats the part number for the discs?
This is a old post but bump it up..=)
i have a Ac cobra replica with Ford sierra uprights.
i have sierra brakes with solid 240mm in front and drumbrakes in rear, now i want to fit the 283mm disc in front and later upgrade the rear to disc also.
my question is, can i use the existing sierra calibers and only buy diffrent carriers to suit the 283mm?.
any tip to solve this would be great.
i live in Sweden so my english is so so..=)
