Wheel PCDs for 'other' cars
« on: January 02, 2011, 12:03:00 AM »
Does anyone have a ready list of cars (Aussie would be better) with a 5 stud PCD that is the same as my 1970 C3 (my searches indicate it's 120.7).  I have found a number of places that have stud patterns and general offset guides for each series of car, however you have to click through them individually to see if any match the vettes.

Hoping someone has a ready list of cars and their wheel stud patterns, offsets, hub diameter, etc.
Cheers

HQ Holden.
Don't let anyone tell you that commodore rims will fit (120mm PCD) That 0.7mm does matter.

mate, i've been looking at buying wheels for my 68 for the last 3 weeks. i measured my wheels, and got a negative offset of 12 to 14 mm. the first issue is stud pattern, 120.65mm, the other is that most wheels have a positive offset between 25 and 45 mm. the best i can find so far has an offset of +15, these wheels are not factory drilled, and still i have to work out what exact adaptor plates size  i need to get made ( ~ 30mm). so if the stud patern is same, good luck with the offset.

'New' cars all have an offset of 35-45mm.
Older cars range from 0-15mm.  They are hard to fond second hand, but there are a few options new.  I think the main problem you'll encounter is the calipers protrude past the hub face. If the rims haven't got the clearance for this, they won't fit.

Don't use spacers/adaptors.

I've never found a rim over here that'll fit.

Are you looking for wheels the same size  or are you looking to go up to say 17's or18's.

Not sure what local ones would be ok though but heaps available in the US.

If you dont want to do any mods to your trailing arms (e-Brake brackets) then you can go with -

15, 16, 17 or 18 x 8" with a 4" backspace and 5 x 4.75".

Standard a C3 corvettes tyre height is about 27". so use  a site like below to get the tyres the correct overall rolling diameter.

 I have 18" x 8" coy C5's all round with 245/45/18 front and 255/45/18 rear on my 71.

I was a bit concerned re going from 15 to 18 it would get more harsh but it rides great, very smooth.

The previous set was Michelen 215/70/15's white stripe tyres (almost new) but the 18's almost seem to give a smoother ride, possibly because they are wider and spreading the impact of any road undulations.

No rubbing on lock at all.

Am considering lowering the car 1 more inch front and rear so it may get a bit closer then.
