Hi folks,I've got a corsa b,1400 i,1994,it has 14" mags on it.I was thinking of putting 15's on it off a later model,anybody tried it?
The reason for doing it is better petrol economy,and more top speed for the same revs,plus more between the gears,E.g.-instead of 0-20mph in first,maybe 0-25 and so on thro'the gears.
Every inch on the diameter of the wheel gives 3.14" on the circumference,which is of course 3.14 inches more per wheel revolution.
The speedo would be out of course,but can be marked on the glass with a marker pen,with the help of a mate pacing you in another car.
Changing the subject,will a 1600 astra head fit on my corsa,and are the valves bigger? and,how many thou' will the head stand machined off. Also,will an astra 1600 engine fit in it?
I worked in the experimental toolroom at general motors Holden Melbourne in the early 60's,anybody still around from then?We used to use the airstrip on Salmon st for testing hot rods and bikes,and watch the Drag racing at weekends.
Looking forward to your replies guys.

Late model 15s will be fine.
Engine I'm not so sure about.

Thanks for the replies gentlemen,
I bet I'm not the oldest boy racer in town,tell you what,I'll race you for a Dollar[25p]Haha
Boy racers become old boy racers sooner or later,so beware me olde china.
Are we supposed to throttle back as we get older,I think it wouldn't be long before we became extinct.
I intend to carry on wearing my lead boot,and to go out firing on all cylinders.
Here's one for the limit pushers,get rid of your 'cat'between mot's,get a big bore,and test your bottle,[if your brakes and suspension are up to it]
Enjoying the chat guys,off to get s=== shaved showered and shampoo'd,it's Friday night,and the ladies are waiting.[Good old mr pfizer] the alchemist who invented Viagra.

If you have the correct tyre size then the rolling radius will be the same which won't make your car any faster etc. In fact it will most likely make it slower because the wheels will weigh more.

Hi,
I put astra van wheels on a nova,it went round corners like it was on rails,plus the extra diameter increased the cruising and top end speed for the same revs.The extra weight seemed to hold it down better,especially in the wet.I suppose expensive boy racer wheels do conform to the original circumference,and keep the speedo configeration the same.Thanks for the reply
