Wilwood clarification

[Imperial_16v]

Hi all

Just wasting some time looking at the Wilwood setup that some people run on the Williams. Seems there was a group buy a few years back also.

The caliper used, I believe, is the Forged Dynalite Caliper (120-6805). Product details here:-

When I was doing my searching I came across this thread:-

http://www.williamsclio.co.uk/forum/...wood+group+buy

Tony mentions that "you use standard size discs, so either use your original ones, or buy new 259mm size ones..." yet if you look at the caliper details it suggests a thicker disc is needed; minimum of 24mm. The standard Williams disc is only 21mm thick (and that's new, as it will wear down further over time) and same for the larger 285mm disc (which K-Tec offer on the big break conversion from the R21 2.0 TXi).

What problems will there be if you run too thin a disc?


Anyway, I've had a trawl around to try and find a disc that fits within the caliper spec's and came across the front discs for the Vauxhaul Combo 1.3 TD (2004).

It is a vented 4 stud disc, 280mm in diameter (so slightly smaller than the R21 disc but means it will still fit) and is 25mm thick when new. In addition, the height of the disc is 43mm. Only 2mm more than the standard Williams disc, which is 41mm. Seems to me it would be nearly perfect. It just beats the minimum disc depth for the caliper, and, falls nicely between the minimum and maximum disc diameter for the caliper.

What do people think? Would it be a suitable disc if purchased?

My next lot of questions are:-

1. Where do you get brackets from for the caliper? Do you have to find a local metal fabricator?

2. What brake hoses do you need? Do standard Williams hoses fit, or do you need some funky banjo setup?

3. Do the standard bolts work? Again, if not, do people know what size is needed?

Cheers.

for ease of fitting I would look at 172 disks. Cheap too

3mm off thickness wont make a lot of difference in reality. I ran 28mm thick were 32mm were specified on a 200sx, and it wasn't noticable at all

You do need longer brake hoses and some longer bolts

Also interested in where to get appropriate bracketry!

Thanks, yeah I saw that the Clio 172 discs were possibly also an option:-

Thanks for the reply. You don't happen to have anymore info do you, on the specific lengths?

Yeah that's always the thing that stumps me (or puts me off). If it were a case of shop A sells the calipers and hoses, shop B sells the brackets and bolts... excellent! I hate not knowing where to get stuff.

yozzasport used to sell a complete kit for this iirc including brackets... might be worth a try?

Worth a shot, thanks.

Sorry no info on the lengths, just took my bolts to a local nut & bolt shop & said I want some a bit longer & ended up trimming them down a bit

hasn't existed for years. He ****ed off to Australia IIRC

OK, that's not a big deal I guess. Any idea on the fitments for brake hoses?

Thanks again.

Ahhh nevermind. :(
