Thanks in advance,
What are the smallest wheels that can fit over the standard sierra disk braked rear, ie the standard cast bearing with integral brake mounting
I know westfield and catherham can get down to 13 but they use a smaller dics arrangement
Cheers
David
I'm using Mk3 escort discs with sierra calipers in Revolution 13" wheels with no bother. I had to take about 0.5 mm off the disc diameter, but that was to get inside the caliper dictated by the carrier bracket geometry, not because the clearance to the wheel was low. HTH
Thanks for the reply
So your not using the standard sierra brake fitment as cast into the bearing holder?
Any piccies
Cheers
David
I'm using stock Sierra rear calipers and disks inside 13" Minators.

if your planning your build why not use lobro flanges on your diff unit and bolt the discs on inboard at the rear which will give you the option of
10" or 12" wheels .
ive gone for 10" wheels on my bec kitten and have mocked up a rear bike disc and front bike caliper which will just sneak inside a 10" wheel
for the front brakes and have mounted my rear disc direct onto the diff unit i built as it has no actual diff.

my shafts are vw lobro inner and drum braked sierra outer using the ford bearing carrier and re drilling the hub for mini wheels as z-cars do , if you
turn down the hub 1275 discs will fit giving you plenty of clearance for calipers, i have a drill jig to place over the ford hub to change it to
4" pcd if you need it
i imagine all the z-cars run 13" wheels but i think the ride would be better on 12,s with a slighly taller sidewall as it seems generally
accepted that sevens handle better with a slightly taller sidewall ie 60 series rather than 175/50 13

looks like you have gone for a de-dion beam too then

About the width of a chocolate mouse's cock. (© Barry Sheene)
I had to bend the handbrake arms slightly to get clearance, but the main problem was the long bolt through the lower wishbone and upright - I had to
shave 1/4" off the height of the bolt head in the lathe.

ive made my car 6" wider track front and rear to give it a bit more stability as im sure the kitten is longer wheelbase than the mini but
49" track

bloody hell, bit sharp there!!!
we all try our best, I usually refrain from answering stuff that I can't answer fully but most are only trying to help!
I was going to say nice to see some good welding on here, but with that last post.............................
i fitted capri 2.8i 13x7" alloys over standard sierra rear disks/calipers. i had to bend the handbrake lever slightly to get clearance, pics are
somewhere in my archive.

no spacers involved, standard wheels as were, though i think these particular wheels (or capri ones in general) have a very low offset (et5 rings a
bell) hence they stuck out of the arches so much.
The thickness of the alloy used and the design of the wheel makes a difference to the clearance of the handbrake mechanism. I plan to get some
compomotive cxr's which marc @mnr says clear the handbrake (with the same mod as i've already done) and are available in more suitable
offsets and are nice and light.

Bear in mind though that front and rear tracks being vastly different is none too clever an idea and you don't want huhe offsets (i.e. very small
et numbers) on the front as you will get bad steering kickback..........
worth bearing in mind before you go buying wheels.
(ps. not trying to be obstructive, but I have built a number of cars from scratch over the years and have come up against all of these sort of
problems myself and know how bloody annoying they can be!!! )
if the alloy clears the handbrake bit then the et is irrelevant for that reason, a low et or deep dish type rim could be a way round but it'd
have to eb a negative et to avoide getting close to the caliper and not really workable for this type of car imho.
find a wheel that fits and get the offset to suit the track width/suspension rather than to suit fitting over the discs/calipers.
