Title: Lowering and Mag Wheels
Post by: grey58fc on December 16, 2009, 10:01:56 PM
G'Day guys n Girls,
i was just wondering, if i lowering the effie 2" on lowering blocks bought off ebay, what would be the biggest wheels i could fit under the rear arches withouttubbing? i just wanna give my car a bit more of an aggressive stance so i was thinking maybe 15's or 16x8(??) on the rear and 15x5's on the front.. what offset and stuff like that isrequired? and what is the exact stud pattern of a FC 5x114 ive heard but i dont think this is true.

Generally 7's on the rear and 6's on the front. You will have to roll the guard lips to help with clearance. You need an offset similar to stock FC rims, without a huge dish in them, ie the fronts want to be as close to the tie rod as you can go and the rears want to be spaced evenly between the inner & outer guards. The FC stud pattern is 5 x 4.25 inches (107.95 mm)

There is not much choice around in larger diameter wheels with early Holden stud pattern

Ford is 5 x 4.5 inches (114.3 mm)
HQ / Chev is 5 x 4.75 inches (120.65 mm)
Commodore is 120 mm

thanks heaps mate!
really handy!
i really wanna set of those old skool looking "dragway wheels" i think theyre called, theyre five spoked and the spokes are like rounded and not 100% sure what theyre actually called, but ill know when i find them and then all the info/advice youve sent me will really come in handy!

mate they sound like dragways .maybe you could get them in 15 inch ,not so sure though.
i'm running 14  x 7 inch steelies on a  4 3/4 backspace with 225 65 tyres on back,and lipped guards .
you can just run ya fingers between tyre and guards,doesn t scrub unless under lots of load

yeah i had steelies off my hk premmy on it with big wide whitewalls, but only problem was.. the car didnt move because they scrubbed so hard on the suspension components, are back spacers legal? cos id love to get those wheels back on it! only need to space out the frontend like 5 mil

Spacers are a NO NO  you can get the centers moved in the rims to change the back space so they fit ......FC427.......

My XU1 has factory fitted spacers.....................

really?? so i could get away from the po-po by saying there a factory item???

I think the concern isn't so much the police but the extra loads that pushing the wheels out further will create. Wheel studs and wheels bearings especially. If you only need a couple of mm I can't see how it would be a problem however if you need more than that then FC427 is spot on. His idea is the best answer.

FYI the factory XU1 spacers are 2mm each, not much in theory and the last LJ XU1's had two on the front and two on the back. Mines in the first 100 LC XU1's built so only has one on the front.

You can buy these as repro's from here ($2)

thanks heaps man, so if i put two on each side at the front it would be a go-er for my premier wheels?
 :P
hahahah there not much biggr wheels just that there square edged radials look a lil tougher and aggresive, which in the art of female chasing and "lapping" the main drag of ballarat, the skinny cheese cutters probably wont do it!

Think metal spacers are OK if welded to the rim , would be a lot cheaper than moving the centers if money it tight ......FC427.....

OK, I get it now.

You'll also need a bag of cement on each inner guard to lower the front. Shut the bonnet and everyone will think its been professionally lowered  :P

Two other things you'll need - the choke pulled slightly out (simulates bigger cam) and a screwdriver through the muffler (fat exhaust noise).

Oh, and a packet of condoms.

See, you clearly ain't gunna get that sort of advice from your Commondoor mates. ;D ;D

Good on you for being a young bloke into old Holdens.

hahahahaha i didnt think bout that!
hahahahahah or i could just ghetto it and crack out the hack saw and cut the springs in the front hahahaha
nuh my dad is paying for a good sounding exhaust system, but ill lower the arse with some 2.5 inch lowering blocks!
when its all done, ill post some photos, at the moment im getting all the rust off the floor with a wire wheel!!! FILTHY job hahahahah 
thanks for the advice mate!

A cheaper alternative is to head down the local primary school with 4 sacks and raid the sandpit  :P

as ed said,GO GHETTO!
just to add a spanner in the works,i have been reading a chassis engineering book by herb adams and there is a page dedicated to lowering your car with an oxy!
being a metal fabricator myself i have thought this the biggest no no.
in the book he cut the top spring then heated the top 1/4 or so of the coil then smashes it on the ground to flatten it.
of my knowledge the grain structure will change in the heated zones but your spring load shouldn't change as the bit youv'e flattened is only to seat it,so the change in grain structure would affect your spring load so minimally it would not be noticed.
still i am very sceptical .
mate if ya broke,
chop it with a 4 inch grinder with a 1 mm cutting blade(i didn't say that did i) ::)
