New Vauxhall Offset and 5 stud conversion...

[ade]

couple of questions...

Have had my ear bent re my project and a bigger set of wheels.

These have been suggested -

however -

1 what offset are they and what rim size (eg 16's).
2 how difficult is a 5 stud conversion and whats needed?
3 is it worth it?


Ta muchly

[ade]

wheels are apparantly 17's

[ade]

alternatively what about these -

I'm sure you can get something similar to that one in 4 stud, I saw a Nova posted in another thread with some on. Might have been 15" though...

Was it orange Jack?

[Jack]

Red iirc. I'll go see if I can find it.

[edit] Nope, it was white lol

Ahhh not what i was thinking of! hahaha

[ade]

mmm - not quite the same - I'm looking for big surface area...not bad though.

What about 5 stud conversion. Anyone dont this?

[Adam]

Try R1CH

Think his is 5stud

The wheels on that white nova are 16" Corsa C/Astra alloys iirc

[novacabrio]

Those corsa VXR rims are 18s, unsure on offset or width

[mikey14sr]

provided they haven't changed the pcd of the studs, it should only need the same as any other 5-stud conversion.
Cav/Cally/Vectra front hub centres with either wheel bearings that match both the the hub and steering knuckle, or machined knuckles and larger bearings at the front. At the back Cav/Cally/Vectra rear hubs in place of the nova stub axles, basicly a rear disc conversion with 5-stud hubs.

[ade]

cool. cheers matey!

[Dod]

Werent all the newest Vauxhalls et39?

For the 5Stud Conversion, for the rear anyway, Get a scrapped Vectra, Pull the rear Hubs off it. If you have Discs already on the back of your Nova, you're away. These should bolt straight on providing the centre of your adaptor plate is wide enough to clear the sensor in the centre, rear of the Uhb. All late spec Cavs and GSi Astras had these.
As for the front, iirc you have to get the 5 Stud hub, get it lathed slightly and pressed in with the bearing. I cant confirm this though, I'm going with what I've been told on this one.

[Ben]

Try to use cav rear hubs as the backplates on the vectras are wrong, the cavs are better as they come off a beam wheras the vectras are irs.

[Dod]

As above.

[Ben]

Infact thinking about it i have a set of V6 front hubs machined down to nova bearing size and a set of cav v6 rear hu bs all ready to go if you need them ade, there from when i was going to do the corsa but gave up.

[The Simps]

As said above, going 5 stud is easy. See where Nova Coupe thread for converting a rear beam for vectra 5 stud. Another benefit of using cav stuff over vectra is cav discs are smaller, the vectra ones are HUGE!!!

Just need to find out what the offset is mate and if they're the same.

Chris Astley sells brand new machined down 5 stud hubs & bearings at a good price. Its where I got mine from.

They fill 15's very nicely though!

[Ste L]

what you gonna do about drive shafts & cv's though..

do most 5 stud hubs use big block type cv's or am i wrong?

[Ben]

Yeah they do, the Corsa C SRI CDTi is a five stud, unsure what gearbox and shafts that uses.

[ck]

use cavy v6 stuff for the rear 5stud. the vectra stuff is wrong and needs modifying to fit. only problem is the only way to do fron 5stud is you need to have a big block gearbox and big block shafts. im pretty certain there are no hubs or cvs ever made that allow you to use small block shafts and 5stud hubs...

ive done the stud before so if u need any info just ask..

more suited to big block engine i guess...

unless you get cutom shafts, or some cut and shut's etc?

[The Simps]

what engine will he be running?

[Ste L]

what engine will he be running?

it's a 1.6 gsi iirc

[The Simps]

all that work going into it he needs to upgrade that ;) lol

[Stuart]

personally I dislike the machined 5 stud fnage route.... do the unmachined versions fit into the Corrado wheel bearing that only needs a little machining of the knuckle which is less likely to fail (unlike the machined flanges I've seen a few die on)

Ade, those big ass wheels you linked in the 2nd/3rd post are likely to be from an omega which is very low ET30's

This looks awsome :thumb:

[tom_beverley]

Or, if you're still keen, if you're going to be using a LSD, make sure you get one with the large side gears to enable use of big block shafts ;)

I didn't realise this until after aI bought one with standard side gears :( But, I have an excuse to stick to small block shafts and 4 stud lol

Aye but you need to get the steering knuckles machined to accept the larger bearing, there 4mm larger (O.D) from memory.

he mentioned that in the message you quoted ;)

saying you have to machine it alittle :thumb:

[R1CH]

Thought he meant that there was still a little machining to do on the actual hub (which there is), even if your using the larger bearing.

A thousand apoligies !!

[Stuart]

lol.

does the larger bearing still need the flange modding?

hmmmmm I wonder if the MK4 front struts (complete) etc would fit with minimal modding...

[R1CH]

Ever so slighty, needs a bit machined off the backside of the hub to clear the circlip in the knuckle, and a bit off the width where the bearing sits on as the bearing is narrower than the Cav one. Nothing thats gonna weaken it tho.
Heard a few folk mention thats possible to use Vectra knuckles / hubs, supposedly the only difference to the Nova knuckle is that it uses a larger diameter bottom ball joint.

[The Simps]

its all about the quality of the machining to the hubs.

[Ben]

The VW bearing route is much better, the complete machined hubs with gm bearings do fail sooner or later. your removing nearly half the thickness.

[phazer]

From what I can find the Corsa 18's have an offset of 45

The rim is 7.5x18, Tyre size is 215/40/18
