j333evo, been told you can help - Alloy's, can someone please check this?

Hi everyone

I've just bought some new ally's for my sei, and i've done some calcs to find the spacers that i'll need to make them fit as they should.

Was hoping someone could say "Yes, thats right" or "no, your a muppet, this is what it should be"

I've gone from the std 5.5JX13 ET29 rims to a 6JX14 ET35 rim. The inside of the new rim rubs ever so slightly on the end of the steering arm at the moment - so i cant fit them yet.

Soooo this is what i thought

If it were a straight swap to a 5.5JX14 rim, i think i'd just need a 6mm spacer to return ET from 35 to 29mm as standard. Is this correct?

However, as i've gone to a 6J, that is .5" wider - 12.7mm to be exact, i will need another 12.7 / 2 = 6.3 mm added to the spacer to take into account the wider rim

So basically what im saying is i think i need either a 12mm spacer - is that right? From looking at it when fitted, and where its rubbing, i reckon i could easily use a 10mm, but i'll see what you guys say

Also, anyone on here fitted a 195/45 tyre to a 6J rim? Coz thats what i want

TIA

Dale

I currently run a 195/45/14 tyre but i am not sure how wide it is.

I have 10mm spacers on those.

The best people who are knowledgeable are mase (the apprentice) and j333evo (the god) they will be along in the morning and offer the best advice

let me first say that unfortunately u got the wrong standard offset, the standard offset for the cento is 30.5mm, and they have 3mm spacers on the front making that a 27.5, NOT 29!!!!!!

and to be honest mate... it isnt that exact, u could get away with a 6mm spacer for those wheels and never have a problem.

i have 6x14's on mine, with 185/50 tyres, they are 36mm offset, and i am only running 5mm spacers on the front, and they only catch when reversing on full lock, apart from that they are fine.

however, 31mm offset on a 6" wide wheel is the highest offset u can get as there is maybe 1mm or even less between steering arm and the actual rim.

now usually i would say that for a 6" wheel u should be lookin at running an offset of 28-29, but i am running a 31mm, to keep the wheels in the arches as much as possible cause the car is so low the wheel wall catches on the arch liner.

any help?

Thanks for the replies lads

K, well, i got the 29mm figure from a cinqs/sei's website - cant remember the addy, as i'm at work, but will post when i get home.

Yeah, looking at it saturday night, with the amount it was rubbing the steering arm, i thought that might be the case, but i wanted to be sure.

Yeah, i think so My car is only lowered 40mm, so shouldnt have quite as big a problem with arch rubbing as yours.

It looks like my initial thoughts on saturday were right, and i would just need a 6mm spacer - that was just from looking at what was happening behind the wheel, lol - but then i thought about the width of the wheel and started reading things, - we know where reading stuff leads, lol.

Hopefully j333evo will pop along and enlighten us with his god-like knowledge

yes mate... it is popular belief that it is 29mm, it was actually J333EVO (aaron) who told me that it was 30.5, not 29.

and to be honest he will prob say the same thing as me, the general rule of thumb for wheels on a cento is:

5.5" wide, 30-31mm offset.
6" wide... 28-29 to make sure they dont stick out too from the arches.
7" wide, 18-20, but they WILL stick out from the arches makin them not totall road legal.

aaron does know his stuff in all fairness to the guy, but im younger an better lookin...

What Mase has said is true (see he does learn as his quarterly report card will say) the standard off-set is 30.5 as its actually stamped on the wheels, you can't really argue that one, tho Sei Abarth wheels are stamped with 36mm off-set but those cars are supplied with a stud and spacer kit to allow fitment.

Again I agree with Mase (only cos I told him before) for a 6" wide wheel I would recommend an off-set of 29-28 as being the best to go for as you made a small error in working out how to add on off-set.

Yes it is 0.5" wider, but that is overall, the off-set is worked out to the mounting face plate, so you don't just add on 6mm to your 35off-set to get same off-set its not as wheel I wider, you have to take into account that there is more rim either side of face plate, and balance up where you want the extra width to be, you don’t want it sticking out to much, but you also do not want it fouling things.

There is a very good link in the FAQ section on off-sets that’s shows you how to measure.

There was one discrepancy with what Mase said, i am infinitely better looking, taller, and with my advanced years over him, comes way more experience

that means i win, cos I get a decent accent unlike your made up one, and as demonstrated by my bro's trip to New York a few weeks back, q-jump entry to one of the worlds best bars http://www.worldsbestbars.com/city/new-york/hiro-new-york.htm in NY is assured with a kilt on and the endless amount of girls wanting a pic with you is a consequence, plus overnight stay in Brooklyn with half Japanese/Canada PA chick is an assured probability, lol! :worship:

Hi guys, thanks for the reply's

[/HIJACK]

I tried to look on the inside of my wheels for the offset, but i couldnt for the life of me see it, lol. Wasnt arguing, just saying where i'd got my info from, coz everything you see on the internet is true

I saw the FAQ on how to calc offsets - but surely as the offset is taken from the center-line of the wheel, an offset of, for example, 30mm will be the same on a 6 or a 5.5 inch rim, its just that the backspace and the value from the mounting plate to the front of the rim will be greater?

Thats why i thought i'd need a 6mm spacer to cancel the difference in offset, then a bit more to take into account the fact that the backspace will be greater on the 6 inch rim?

Please bear with me, if im asking stoopid questions or have misunderstood the FAQ, im trying to understand how it works

I think you're saying i need a 6 or 7mm spacer to correct the offset, back to 28 - 29mm, and that will suffice?

Dale

I think Dale would have found this info on the Cinqs/Seis Yahoo group.
