I thought CR use Commodore hubs? Same as the Harrison.

Cheers

Why is a stepped rim a bad idea apart from aesthetics?

aesthetics would be my main concern, although the structural strength of it might come into question too? Just guessing without thinking about it to much...

Mando

i have just had a go at uploading pictures for the first time so if look at them in my prifile you should be able to see two shots. I hope to put more up now i think I have sucessfully done two.

As for tyres i went with Kumho ecsta XS in 18's as I found very few tyre options in 17inch size and width I wanted so felt like I had to go to 18's.Tyre size as follows with prices paid plus freight on top. 245/40R18 KUMHO ECSTA XS 275/35R18 KUMHO ECSTA XS

SUBTOTAL: $768.00
FREIGHT: $284.59

Depends on the Generation of chassis Geoff,

My 2nd gen chassis uses Jag front components and AU Falcon rear. Ian's new chassis uses hubs from the VE commodore all round I believe. The rear end on the new chassis is a bit narrower but I think the front is about the same.

Cheers

Thanks Mike.

So Modena's chassis has a jag front end if Vintage Wheels do not fit.

Cheers

FYI: The new chassis is VZ front Hubs with Ian's upper and lower arms and VE rear with standard lower and Ian's upper arms. I dont know why Ian didnt use VE front hubs.

Mine is the VZ front hubs and VE rear . To acheive a change in front offset I did even consider a change to the upper and lower front A arms but did not want to go to that effort in re engineering the front end geometry so it would still work properly. Another idea was to cut and shut the flares on the guards to allow for the expantion of the front track due to the extra width Vintage wheels would require , But the body had already been painted at this time too late. FYI - I had originally made Vintage Wheels my first choice of manufacturer and this was after seeing many different wheels and the feed back from Club Cobra was only ever posative I would still prefer Vintage Wheels if they would fit.

My front wheels are 17 x 8.5 with 5.00 backspacing. Am pretty happy with the way they look.





Cheers

Scoob, I love the look of the outer rim used on the 18" rims, they're just great. The centres are the same as used in the 17" rims. A guy I know here in Adelaide has 18" OZ Wheels on his Cobra but with about 3" on the front and about 6" on the rear. They look magnificent. I asked OZ Wheels what sort of cost would be involved to use my centres to make a set of 18" wheels and he came back to me with a whopping $2400. I figured for that sort of money I'd be better off getting 17" knock on's from Vintage wheels and adapting them to my front end as Aussie Mike has. I haven't dealt with OZ Wheels for about 18 months but they were still OK back then.
How about posting some pic's of your car, it's great to see how different people do things!

Ptrefry, can you show us what your new hubs look like as well as your knock on wheels? Thanks.


Regards.

My wheels are OZwheels but I supplied them with Pin drive adapters I got from Superformance and they machined the centers to fit.

I agree with you Mando, the 18" rims on 17" centers look good. The angled step rather than rounded from the center to the rim looks much better.



I probably could have added another 1/2" of dish on the front but I don't like the look where the edge of the tyre is right near the lip of the guard. I like the tyres to tuck in and not rub anywhere.

As for the difference between the Harrison and CR front end, they are probably both built with different suspension pickup locations. The CR runs a wider front with a lot of offset on the wheels to reduce the scuff radius.

Someone here may have a picture of a Harrison front wheel.

Cheers

Good looking car there Leroy. Looks like the Harrison has about another inch of dish on the front wheels over the CR. That would probably explain why vintage can do a fitment for them and not the CR.

Cheers

Mando, the wheels are the 3 piece ozwheel ones.

I changed the outer rim for an extra inch of dish and then machined the inner face (12mm) to bring the wheel in a bit but maintain clearance. In general I wanted to change the busy look of the wheel. I have had the centres powder coated in a satin gunmetal grey, the satin finish is to minimise the shine or reflective surfaces on the centre.

The other thing that I did was replace the mounting bolts. These are now a low head high tensile which sit flush with the centre for a smoother look. The bolts have all been treated as a HOT black oxide (not normal black oxide). When I rebuild the wheels I was happy with the end result.

The rears were rebuilt and machined so I could get maximum dish but still have clearance.... its tight but it works. Rear tyres are 285 40.

However I do agree that the 18s and the rim profile look good.
