HiSpec 283mm Billet 4 Brake upgrade for an early Griff

[will.spiers]

Hi all,

I'm currently in the process of upgrading the brakes on my Griff 400 (Currently running the early 240mm discs). Am I correct in thinking that it has the basic 1.6 Ford Sierra hubs and thats what I need to quote to get the correct caliper mounting brackets?

I've done a search on here and I can see this has been covered before but with conflicting opinion. As i'm a mechanical numpty I want to make sure I order the correct kit!

cheers,

Will

I've got 4 pot alloy Billets fitted to my Griff, stops like a b'stard at the moment.

Will be put to the test when i put in my 4.5BV engine

I have them fitted on my 500 and I am very pleased with them but not tried them on the track yet.

I have them on my Chimaera as well and they are really good imho, much better than the standar and look great too with grooved discs.

They do but I was under the impression that the 4.3/500 used different hubs? Speaking to HiSpec direct they couldn't guarantee the kit would fit the earlier hubs - does anyone know?

The 285mm Billett 4 conversion is for a Sierra hub carrier and will fit under a 15 inch wheel, the only difference to the Ford hub carrier from the standard Ford item is that the bottom ball joint has be nachined for a larger taper to accept the Lada ball joint from the TVR lower wishbone, these were machined by TVR.
The two sizes are 240mm disc on early cars and 260mm disc on later cars, mine was the 240mm type originally, within the kit you get a machine aluminium block which bolts to the Ford hub (original caliper mounting) and the new caliper bolts to the block. I have seen the kit fitted on later cars that would have had a 260mm fitment.

You can reference the hub casting number to Hi-SPec to be sure, i recall they are 3 digit number.

I remember reading an account by a PH'er here last year of some work which ended in him wining a court case against them. It seems to have been deleted though. Yellowgriff I think.

Yes there was but in fairness that was to do with the rears they do - quite a few on here have the fronts with no probs at all.

Yes that was me. Still havent been paid out and 7 times to court so far,,
