jst grinded my arches! (now with pics!!)

[Stanley]

jst grinded (ground or wateva) my rear arches to accomodate my et35 16s.

no lip at all = no scrubbage at all!!!

kicks ass.

they are wide as fook!

look great

hopefully pic soon.

[epo]

i was doing that last weekend to a mates car he finished it off and made a good job of it what did you treat the arches with afterwards :?:

[novaadam]

dont the car fail mot for sharp arches if u cut it all off wot do u need to treat it with :roll:

[Stanley]

i used underguard or underseal or some shit like that.

black gloopy stuff!!

lol

nah theres no sharp edges, i used a file and got rid of em all.
not bad considerin ive never used an angle grinder before!!

jst gave it a bit of stick over a hill 5 mins ago and theres a wee bit o f scrubbage on th left side.

al get the grinder out again after it stops rainin!!

cant beat a bit of metal destroying madness!!

[Adam]

No offence for the work you have done, but why didn't you just buy the proper offset wheels in the first place :wink:

[epo]

i think its down to what comes along at the right price i know this was the case for my mate

16" wheels off a renault 19 16v with 205\45\16's ?70 wheels arnt to bad just one of the tyers was worn

[robb]

Remember that the width of the tyre is going to affect what offset you need too, I had exactly that as above et35 205/45/16 and they used to rub with a full load on both sides. I too got rid of all the lip and ran -40mm.

[m.d.]

16s will rub on a nova without grindage, ive had to remove all the lip too, well if the wheels are of a decent width anyway,

[Stanley]

i think its down to what comes along at the right price i know this was the case for my mate

aye thats quite right!

needed a set of alloys and they were the right price and not bad condition.

and boy do they look good.

the offset makes em look a hell of a lot wider

although it looks like a tractor due to ride height!!

-60mm?? me thinks so!!

[novaadam]

can u post some pics mate.

[hendrix]

Cheers epo for lending me ur grinder to finish the job - it certainly stopped most of the scrubbing. I treated mine with waxoyl. Seems to do the job fine! I had to take the 16's off cuz the car was bottoming out when going round corners and puttin dents into the wings :lol:
atleast they werent like the 14's i had that were 185 wide and they used to scrub really bad!!!! :roll: crap offset but for 30 quid they looked good : :lol:

i thought renault wheels are near enough the right offset for vauxhall's :?:
et41-49

[hendrix]

they werent the standard renault wheels, they are some team dynamics wheels but me and epo couldnt see what offset they were

[Stanley]

pikchas!

what yas think of my handywork?

need more pics?

[robb]

Nice,

just gotta lower it a bit,

40 front 60 back

[epo]

older renaults also have a lower offset number its the new ones which are closer to the vaux offset

i cant believe noone has said how much this weakens the back of the car.
The inner and outer arch is spot welded together along that lip,when you gring them back you grind the spots off,in a crash the wings will just ping apart and the back end will squash in alot farther than normal,making the car non repairable.
Folding the arches up flat is the proper way to do it,still retaining the full strength,then sealing it properly.

the reason i never said anything is because i didnt know that

learn summat new everyday :+:

[broody]

Also over time the two skins will come apart.

[burgo]

thats why u weld em if u grind em, surely there aint people driving about with the two flappin in the wind lol

[robb]

How the hell to pro's 'professionally fold' the arches then?

I can't understand how to do it good.

I know you can get a blade and score the paint to prevent it going wrong then hitting it with a plastic hammer and piece of wood.

correct??

you mean like CP has done on his?

he was talking to some rally prep places prior to cuttin his off and they said that the outer skins hold NO strength in them. its all the inner arch and sills that do the structural work.

i dont think cp even welded the arch skins back togehter either, he just bungs sealer and grease down there to preven rust

[robb]

Hey take the fibreglass arches they will hold no strength

[Ojc]

Expect your arches to disapear shortly through rust.

[Stuart]

seam sealer, grease and oil inside the arch. that should stave it off ;)

[robb]

Or you could not grind past the spot welds and file it all down then spray it over, mask off the nice paint and spray, or hammerite, good stuff!

[Stanley]

arches were rusted a bit anyway so i though 'ahh what the hell'

it did cross my mind tho but they still semm very rigid and supportive so all is good so far

[danny-g-]

Hey all

on monday I chopped my arches back with an air saw but only halfway across the spot welds so ive taken 3/4 of the lip of an its
still welded together. I work in a good bodyshop an alot of the lads in work said thats the best way to do it aslong as its not showing any bare metal because the water gathers at that point as a lot of you know,
Ive now got 15" TSW razors and im lowering it 40mm this weekend
hopefully,

hope thats a bit of a tip to you boys,

I will try an get some pics up when its lowered,

Dan

[burgo]

air saws are good tools, but fook me are they noisey. does me head in at work and the DA's, thinking about its all noisey :(

[danny-g-]

In work the boss has banned air chisels because when he is on the phone to the customers he cant hear them. lol

[burgo]

air chisles are banned any way, not spose to use them for health and safety reasons

[Riggy]

a proper body shop has a special tool which rolers the arches under and folds the lip properly

and if im right your car will fail its mot if your wheels stick out further then your arches :cry:

[m.d.]

they will only fail mot on wheels sticking out if its too much. i think its an inch you are allowed, and its only the tread they measure so you can have as much rim past the arch as you want,

i personally and the body shop that i go to will only ever cut arch lips away and smooth them as by rolling them you are creating a place for whater to sit and rust your arches out from.

[burgo]

m.d. thats only the case if u dont seal it, if u roll it then seal it it should be fine

[m.d.]

yeah true but id rather not create another chance for the old oxide to take effect. ive seen rust kill arches that have been professionally reolled sealed and painted, not nice when you have paid for that nice full respray

[burgo]

lol true, not sure what im gonna do with mine yet

[m.d.]

it really is up to you but i have ground and painted all of the novas i have owned (apart from the white gte that was rolled and conciquently rusted right out :cry: )

also if your arch lips are rusting anway they wont be able to roll them, and lets face it how many novas do you see with rust free arches untill we sort them out.

so by cutting the lips out you are helping by cutting away the rust too. :D

[burgo]

well im gonna put two new rear arches on it any way and i was gonna roll them and seal them, now im not so sure

[johnny27]

I know this sounds stupid, but i never caught on to the idea, could someone please tell me exactly what part of the arch it is that needs rolled. I thought it was the inner arch behind the wheel the bit that curves out a bit, but now not to sure as you where saying the arch needs repainted? any pics of the part of the arch to be rolled would be great (websites?) Thanks

[robb]

Its the bit on the outer arch, the lip on the inside, alloy wheels usually are a tight fit into the rear arches so some of the lip has to be rolled/grinded away.

[johnny27]

do you mean the lip that sits in a little on the cutout (outline) or the arch? Anyhow why does the arch rub? Is it because the wheel is to wide or just to big like 16's? Cheers

[robb]

Its width.....and go to your car and stick your hand between the wheel and arch palm facing you then close your hand around the arch and there will be a lip on the inside of the arch, that is what gets butchered to fit wheels in.
