5 stud conversion

[Bernard]

I am currently stock piling parts to convert from 4 stud to 5 stud hubs.....can anyone tell me if the standard Lancia Beta drive shafts will fit straight on or will I require Lancia delta Integrale drive shafts.............sorry if this has been covered before

Also has anyone had any success finding 285/40 x 15 or 345/35 x 15 tyres cos I've not !!

(back on line Dave......thanks !):D

My understanding -which resulted in my stockpile- is that you use the Beta shaft with an Integrale outer CV joint. I haven't got as far as assembling them yet. From memory, there was some isue about ABS / non ABS; I'm sure it's in the archive .

[mogul_x]

You can use either a Beta or Delta outer CV joint, but there are caveats, as I understand it:

If you use the Beta CV joint with the Delta 5-stud hub, you will need to machine a few mm off the splines on the inboard end of the hub. The splined section on the beta CV is shorter, and as a result, the splines on the Delta hub will bottom out against the non-splined portion of the Beta CV joint.

If you are using Delta CV joints, but your car is an older Hawk (with the threaded rings from a Beta to hold the bearings in the uprights), you will need a set of early (non-ABS) Delta hubs. If you use later hubs, the ABS ring will interfere with the bearing retainer, and lock the halfshaft.

Later Hawks, with a circlip for retaining the bearings, can use either the ABS or non-ABS outer CV joint.

If I have my facts wrong, somebody please correct me!

Also on this thread .....what about brakes....Alfa 164 or some highly sexual looking direct replacements !!!!...........I have seen various companies advertising ....eg

Hi Spec Brakes.....Tarox.....Willwood.....etc .....what are your experiences ??

Bernard...............

PS.... I do apologise if this has been covered before but then again someone may have a more recent experience.:D

[Andrew Way]

Scott is correct in all he says (well in this post anyway!):D

I just machined my hubs on Saturday to allow me to use my beta CV joints. At the same time its worth opening out the pocket for the nut from Ø47 to Ø50 to allow any 36mm a/f socket to fit (saves grinding the socket down).

I used Hi-spec for my front brakes.

Their Monster 4 Pot is a very low profile caliper and allows the fitting of larger discs than can be fitted with other calipers. They are very well designed, and take the same pad as the AP calipers.

I use EBC Green Stuff Pads and this combination works excellently.

I already had a set of Wilwood Superlite calipers, and Hi-Spec made some brackets to fit these to the rear for me.


When I eventually get started on building the other car, I intend to use Hi-Spec front and rear.




A friend of mine races an Alfa 75 in the AROC series, and he has just been through the process of evaluating varying manfacturers products for his race car, AP, Brembo, Tarox, Red Spot, Hi-Spec, etc. He has decided to use Hi-Spec calipers.

Dave,
What do you do for the handbrake?

It's hydraulic on the current car.

Hopefully, by the time I need them for the new car, Geoff at Hi-Spec will have the 4pots with handbrake facility into production. I've seen the pre-production version, and it should be an excellent solution.

But, we're drifting away from Bernard's original subject of 5stud hubs.

I knew this rang a bell! I posted a photo of the two CV joints in my photo collection. It was definately covered at some length in a previous thread. Try the search function.;)

It's something that does concern me regarding Gerrys proposed production of the cofffin spoke replica Campagnolos! The last 285s I heard of were from Chris Smith but I know he's got none left. The 345s will need a 12 inch width rim but that's not on Gerrys hitlist, only the 8 and 10 inch ones but he seemed confident that someone would make the tyres again soon. Perhaps he knows something we don't. May be worth asking him now before he embarks on an expensive project! The last time i bought 345s (Only Pirellis available) was a year ago from Jim Jeffries Tyres in Warrington (01925261193/266050) and they had a few sets in stock! I actually met a guy coming in with a set of Pantera wheels and US spec Yokohama 345s to fit to his newly refurbed wheels. He wasn't at all happy about not being able to get 285s for the front or that I pointed out that the USA 345s don't have an E marking and aren't SVA compliant and MIGHT invalidate his insurance...
Anyway, give Jim Jeffries a try, if the number is wrong (they have moved recently) come back to me and I'll dig it out. Ask them about 285s as well, you never know!

Tyres don't need to have an E mark to be legal in the UK.

There is a get out clause in the "Motor Vehicles (Approval) Regulations 2000"

It quotes "1. Every tyre (not being a retreaded tyre) fitted to the vehicle shall bear an approval mark in accordance with the requiremets of Directive 92/23/EEC or ECE Regulation 30" - which means a tyre must be "E marked"

But, it then states "Paragraph 1 shall not apply to a tyre fitted to a vehicle, if the tyre provides a level of safety equivalent to a tyre that meets the requirements of that paragraph."

I stand corrected!
Thanks Dave, it's good to know someone spends time reading the smallprint! Does that come from reading rally rule regs?
Guy

[Stratos]

I had to do some investigation into this particular area recently.



You should also be aware that, according to the MOT Test Handbook, a car cannot be failed at an MOT test for not having "E marked" tyres.


Getting even further away from the 5Stud topic now, aren't we.

BUT Bernie asked about tyres as well !

Oh, alright then ..... :rolleyes: :rolleyes: :rolleyes: :D

[Bernard]

NOW NOW boys and girls put your Handbags away !!!!!.....Ive never witnessed an internet scrap before....does it hurt ?

to be fair I did ask about tyres as well because when i change to 5 stud i will need new wheels and TYRES...so the availability of tyres is somewhat crucial....

Hi Spec look a good bet so far particularly if they are doing or hope to do a rear caliper with handbrake facility

Thanks for everyones comments so far !

Bernard:D

[Stratos]

Internet scrap???

No, just friendly banter.



Last time I spoke to Geoff at Hi-Spec, he said the 4 pot with handbrake was about 2 months away, but I've been told that before. Trouble is they are a smallish company, and production obviously takes priority over development, and their sales volumes have been growing every month, so all their effort is naturally directed at getting existing discs and calipers out the door.

[ANDYG]

Morning Dave,
How about a link to Hi-Spec in the "Suppliers Category". (for those who havent a clue where they are!!) :rolleyes:
Cheers.:)

[Stratos]

Will do.

I remember seeing these calipers at Autosport International last year - or was it the year before.

When I asked about them this year, he did explain the same issues about production of current items taking precedence. Well, that's what gets their revenue, so who can blame them.

I like the idea of fitting these calipers too.

[AndyH]

Has anyone looked at /thought of going up to a 16" rim and lowering the profile of the tyre further... does this give any more scope for tyre size..??

I guess it would also allow larger brakes, but don't really know if this is a big problem or not.

Andrew

[David May]

I went for 16" but was disappointed to find a poorer chioce of tyres (especially racers) for no obvious performance advantage. The Image wheels have a deep well and give little or no more room for brakes either. I also think my 40 profile rears look a bit too modern for the car's style.

It would seem that there might be a number of us looking to buy a set of Hi spec calipers around the same time frame. Any chance a (bulk purchase) might reduce the individual cost?

I thought that Hi-Spec calipers were already really good value, but it wouldn't hurt to talk about bulk purchases at some time.

The thing with the handbrake+4-pot calipers is that they have not yet got them 'production ready', as there normal calipers keep them more than busy enough.

Another point is the mounting brackets that will be needed, but unfortunately there is a fair variety of kit types out there which will want them - just among the Stratos crowd, that is.

[guy mayers]

Did you have any luck sourcing 345s Bernard?
