5 Stud Convertion

[Dod]

Right, I'm breaking a Super Touring Vectra this weekend, I assume the Rear Discs, 5std, will fit with the same modifications as any other Rear Disc Set up, but what about the fronts. Whats required?

[burgo]

whats required is either getting the vectra hub machined down to fit a nova bearing or getting the carrer machined to take the vectra bearing

[Dod]

So a lot of hassle. So an engineering firm is needed. I take it the Vectra Hub is too big to fit into the Nova carrier and needs lathed down, or how is the process completed?

[burgo]

no the vectra hub is to big for the nova bearing. as for to much hassle, not really. it only cost me ?15 to get my hubs machined down and then its just pressing them in as normal

[Dod]

Should the engineering firm be able to seperate the Nova Hub as well?

[burgo]

if they cant go to a different engineering place lol

For the fronts, either turn the 5 stud flange down to fit the Nova bearing, or have the steering knuckle machined to accept the larger Group A bearing (The Vectra bearing is way to big to use) then the 5 stud flange will fit the new larger bearing (still a small amount to machine off the 5 stud flange tho, to clear the steering knuckle).
Theres been a thread on MIG just this last week about using the whole hub set up (steering knuckle, bearing and flange) from a Vectra B, supposedly will fit straight on to a Nova, only thing that needs sorting is the bottom ball joint (the Nova one is to small to fit the Vectra hub).
I'm using Vectra V6 discs on the rear of mine, same as a usual disc conversion, bit more hassel tho as the Vectra stub axles use studs and nuts instead of bolts (Astra ect ...), also gotta run the hubs upside down as the handbrake is on the bottom on Vectras.

/\ does that mean you are running 5 stud on the rear or
is it posable/reliable using v6 items and having the discs re-drilled for 4 stud
and have you any pics of how it looks running the setup upside down?
is it still the nova astra ect cables used?

[R1CH]

Yeah running 5 stud, that was the whole point in doing it !
You'll better off with just using Cav / Astra bits if its still 4 stud, the Vectra brakes are a bit to big really, 286mm !!
Use the same cables as you would on a normal disc conversion, Nova long cable, Cav MK2 short cable.
Only difference with having them upside down is that the calipers hang at a different angle.

thanks rich, it's just that im skint at the mo and have no brakes on my xe and have a cav v6 sitting outside doing nowt, pics look like a neet job done

Think that must have been me :D

I took the plunge and I now have a pair of vectra front hubs -hoping they will fit nova struts :confused: - so on saturday I'll have a better idea as to whats required to make them fit

Ah good man Dave, keep us, (well me, **** the rest of them) Posted mate as its something I'd been ken on doing!

[burgo]

(well me, **** the rest of them)

charming

[Dod]

Well, you know what I mean.

[Ste L]

i say tell the rest and **** you off :p

as your not a club member lol

[Dod]

Lol

[RSTChris]

**** hot!!

Im doing this shortly also, just been and bought some machined down 5 stud hubs, won some cav turbo alloys on ebay for ?50 for it, just need the rears and the discs/calipers

Thanks for the INFO

V Nice nova you're building there!!

[burgo]

rstchris are you coming to the rolling road day?? as i have a complete 5 stud rear beam taking up space

[Stuart]

rear calipers on upsidedown..... that must make bleeding them totally pointless, then again the extra air in the calipers might help stop the brakes from locking up lol.

[Dod]

Right, I'm trying to visualise this but to no avail. Has anyone got any pics of whats to be done to what part? Sorry for being annoying, but i'm more mechanicially minded.

[The Simps]

Thats great Rich.

I bought some vectra rears a while back and are gonna run them on my nova. Was gonna be starting on it soon actually. I was just gonna run the cable underneath, but I'm sure it doesn't matter either way?

How do you find running them so big on a stripped nova (mine will be the same)? You using a bias valve?

the caliper's aint upside down. just the hub's..

[R1CH]

I built that beam about 5 year ago now, i wanted to run 5 stud, could find any Cav V6 bits at the time so had to settle for the Vectra bits.
They are a bit on the big side tbh (286mm) the Cav V6 stuff is 270mm (i think).
It was a ball ache due to the stub axles being held on with studs and nuts, that why i had to chop bits of the beam to give clearance to get a socket on them. Might be able to mod the stub axles (tap a thread in them ?) to accept bolts, i'd rather mod the beam so i could just bolt another std Vectra stub axle on if i ever needed to.
For what ever reasons my handbrake is a bit crap, shoes are all ok so could be down to cable routing ? It holds the car still (just) so that does me.
The back end used to lock up if you jumped on the brakes, i'm using a Calibra MC with a Tilton bias adjuster in the rear line, even with it wound right in it still locked, i ended up removing 2 3rds of the material off the brake pads, been spot on ever since. (probly not the best way to go about it, but the pads are wearing evenly so cant see it causing any probs).
Not sure what you'd have to do if using a std Nova MC, change the valve things that are connected to the MC ??

Few pics with some more info ...

Nice one Rich, cheers.

[andrew1988]

That little guide has really helped. Something im looking at doing soon. Anything similar possible for the front using vectra parts?

[R1CH]

Before you follow that 'guide' i'd have a look at Simps build, think his way of doing it is better / easier tbh.

At least you know yours works! lmao Mines untested!
