Will these alloys fit?

[wagits]

Hi there, found some alloy wheels. So far I know that they are 16inch 4 x 100, ET40, off a Corolla. The guy will hopefully come back with width. Tyres on them are 205 by 50. To go on a 96 Mk3 GL Classic 2 litre.
cheers

Should be right.
Golf needs 38 offset so 40 is probably ok.
Check the centrebore.
Try a wheel on the front and turn the steering.

205/50 are usually mounted on a 7", and with the offset at ET40, it would have have the wheels sit inside the guards, though they might rub with such large tyres. Suspension clearance should also be OK. A 195/45R16 tyre would be a better fit for a similar rolling diameter for the Mk3 GL.

Edit: Yes, and like Matt said, check centrebore!

So I understand, with an ofset of 40 will the wheels sit closer to the guard than an offset of 38?

Anyway I think the centre bore of the corolla is 54, I think the Golf is 57 or 67. I have seen conflictng measurements

[rayray086]

Wheel offsets aren't as simple as it seems. It measures how far the mounting face is from the centre. The more positive the number, the further in the wheel sits. It is a measurement relative to the width of the wheel, i.e. an 8" wide ET40 wheel will sit much differently to a 6" ET40 wheel. Muck around with a wheel offset calculator.

Seeing that you've got a GL, you must've had similar stock wheels to mine, which were 14x6, ET38. Using the calculator above, if the Corolla wheels are 7" wide ET40, then the Corolla wheels will be closer to the guard by 11mm more than stock, and will sit further in towards the suspension by 15mm. Note that these values DO NOT account for a tyre mounted. You may have noticed that the overall "difference" is about 26mm, which is equivalent to the extra inch in width. FYI, both values are small enough to not worry about any rubbing, provided you choose the appropriate tyres (very similar rolling diameter, and not fat and bulgy).

So yeah, in a sentence, those wheels will fit in respect to width and offset (if they're 7" ET40) haha.

However, if the Corolla wheels DO have a 54mm centrebore, there is no chance of the wheel fitting on the Golf at all without some major modifications. 3mm may seem very tiny, but in this case it's a huge difference. You can fit large centrebore wheels on small centrebore cars, but not vice versa. If you can, have the diameter of the centrebore measured properly before buying.

Can someone give this brotha a job with BBS or Enkei or something!?? Ray do you have a PHD in Rims and Tyres? Is your thesis on rimology??
Bravo..

[Mrk_Mickey]

Haha yeah +2 for that! Ray's the wheel man, hands down

[wagits]

rayray thanks so much you have answered my question perfectly.

[evorobin]

Ray is correct however I disagree with the centre bore comment. While it isn't something you can do in your shed a wheel specialist will make light work of it for a few bucks.

The chrome steelies on alex's jetta I made came from a toyota and had 3mm shaved out of the centre. Use google/google maps to see if you have any specialists that are local mate.

So I just got on the wheel and tyre calculator. Obvioulsy I should look at something else. No use buying this set as the tyre circumference is too large. So to my next question. On my stock standard setup car, can I get a 17 inch setup on without having to roll the fenders. And then maybe handle a 1 inch drop in the future. Or should I spend the money on the drop first, then get tyres/wheels. I found a Monroe set up with lowering springs on US Ebay for $239 USD. I do need rear shocks as one has decided to let its oil out, and the other seems stuffed. makes the car jump around. Though I may do the front as well, and then get some lowered springs as well. However ringing around Adelaide the cheapest set of rear shocks I can find is $260 for rear and $330 for front Bilsteins. Another place wanted $335 rear and $320 front for Monroe GT gas reflex. Somehow I am thinking Bilsteins should be better than Monroes. But I am an old scholar. If anyone knows where I can get some shockers at a cheaper price I will be grateful for the info.
