Welding and re-drilling a wheel hub - what to look out for?

and lol, I just realized I missed something -- the word "HUB" in the original post heh.

I was assuming you wanted to weld up WHEELS and drill a bolt circle in them to work with your existing 4x100 wheel hubs, not convert a 5x100 setup back to 4x100... that makes a lot more sense now given what you are discussing here heh

Bailiff! Whack his PP.

You know you oughtter get me some rear drums so when i go carve up some as an interim thing we know we van make work I can do several at the same time. Tom is supposed to be getting me some drums so I can start.
Sounds stupid top do the mod the drum thing as an interim deal but we KNOW that we can do that fersure, we're not 2100% positive we can do the MkIV stuff YET.



With a little planning whatever we do to make the "disc over former drum" work can be switched over to the "MkIV into 4 bolt setup"

I've got a set of already "convered" rear disks into hubs if anyone wants them (4x100). Tom?

I was origionally going to use them to go 11" front rotor in the rear, but now that I'm doing the front subframe in the rear it got really easy

Hey, yourz a VeeWee guy. Do you know what the various front SOLID rotor diameters are?
See mosts uz youze guys already have dose 5" or 5.1" diameter solid rears sos youze have the calipers for solid rotors.
Realistically even fast F2 cars used solid in rear so youze guys oughtter be able to survive if we upped the diameter to some around the size of oh, say a 1969 Saab or about 267mm.

Especially if its just a rotor and a caliper bracket plasma cut
And of course a sacrificial drum.

Local victim needed, call now, operators are standing by.

Mk II stuff front solid rotors are 239x12 mm. Same diameter as the smallest vented ones (239x20). In fact they use the same caliper (the one that mounts to the weird antler-stuff on the knuckle - it's just thinner pads for, say a GTI (that has the ventilated 239's).

The rears are 226x10 mm. - so thinner than solid fronts.

Mk I stuff is the same.

So it'll most likely be a problem to mount the solid fronts with the original rear calibers. I don't think there is room.

John,

If you're doing work back there why stay with solid? Get a pair of used rear disks, put them on the lathe and turn them into hubs (or buy mine), a quick as you say trip to a plasma cutter with some dimensions to position the caliper and you're done. (I've got one adapter to fit the vr6 aluminum rear calipers on an 11" rotor, but I can't find the other one....)

If you don't want to go too big you can use the 10.1 MKIII disks or MKII 9.4" vented rotors (4x100 only)

5x100 smallest is 11" off the corrado

Personally to reduce the number of spares, just match the front rotors

PS. I've got the rear beam out of the car if you want a mock up piece to play with for the other boys

OK, boys, fawk the solid former front in the back idea---or----wait wait.
I thought I looked up the piston diameter for the rear calipers and "gave it my blessing" meaning it had to be at leasy 36-38mm diameter

Yeah, Roberto "Nazi de Servicio" and I were talking about how you guys all love to play with 'pooter programs to arrive at conclusions that dis dat and de udder is what you need and how I work nearly always from "what did__________Motorsport actually use on gravel" which seems easier and we looked it up..


SO, come on do you guys WANT to buy vented rotors and calipers?

I'm saying the kick ass mid 90s 240-260 bhp F2 cars all used solid and a AP or Brembo twin pot with 48mm or 2" pistons.

Know I believe there are one or two obscure other brands out there with 4 or 5 on 100mm and I have a feeling we can come up with a cheap reasonable sized rotor with just a little effort.

But if you guys are all clamoring for vented---and I certainly thought of the spares detail, and I think it is pretty legit--- I just want you to know that you probably don't need to.

I'll invent something here but the question is:
Do you want to run out and buy calipers?
(Piston 38mm would be real nice, more and you will have to limit them down).

Yeah Roberto and I were just talking about trying to find a beam to start mocking up stuff, get hold of me or just plain bring it down.

Yeah John I'll be in touch once I get the car rolling so I can get the truck back to where I stashed the rear beam.

Who said anything about buying fancy new calipers or putting front calipers in the rear? Get the MKIV rear calipers and space them out to fit.

I dropped off two mk2 4-lug drums and a stub axle with a caliper bracket on it for John this weekend so he can start playing around with fancy rear brake setups for you 4-lug guys.

I've got a couple of old 5-lug rotors I'll take him later so I can play too
