Arch modification required

  1. #1
    Hey guys.

    Can anyone recommend a company where I can take my car to, to have the rear arches modified? I fitted some 205/50/15 Toyo R888s today, and the rear tyres are catching the rear area of the arches. I think I'm going to need a professional arch modification.

    i had the same problem with a 90mm drop and 195/50/15's.
    i took out the rear liner thingy and took a grinder to the supporting brackets.

    then just painted them up and diverted the air vent (well blocked it up).

    cheap bodge lol

    Mine's not catching on the inner liner though, it's the actual arch.

    It doesn't bend, it would just snap. Otherwise I would!

    which part of the "arch" is it rubbing on ??

    inner/ outer ?? or plastics behind the wheel ?

    The area circled in the picture below.

    Don't think you'll be able to do it without it looking daft.

    In hindsight could you have bought 195/50s?

    Yes, but I wanted to make use of the extra width available with 7" wide rims... I hope something can be done. Surely there's some bodyshops out there somewhere that could do this in a jiffy? If all else fails, I'm turning into Hacksaw McDougan for a day!

    Solid rear struts?

    How about raising the rear by 5mm at a time to see if you can avoid catching that way?

    No, because it's catching even before I go over any bumps. I would have to raise it like 40mm! Which I'm not going to do. lol

    It's not catching it THAT much, otherwise the tyre would have burst almost instantaneously, so I think I'll work something out. HACKSAW! Arggg!!!!

    its only the rear bumper bracket !!

    if you remove your rear buymper and rear arch liners, just cut the steel brackets off and the plastic bit off your bumper. then just replace bumper and arch liners although it may still rub on the arch lines but it wont burst the tyres as theres no sharp steel

    max power haynes shows how

    iv got a pdf version of the max power i can send you if its any help mate, not exacly the best of copies lol blatent scan but might be of some use

    Nick Tynan has this issue with 205 width tyres too.

    Get the rear raised a tad mate
  20. #20
    speak to dannygti he runs 205s think hes higher than you though
  21. #21
    I'm going to have a hack at it tomorrow. I ran out of light and it was freezing, so I gave up. I'm sure I can file enough off...

    As far as i know Danny didnt need any arch modification just raised it, he may have done some though.

    I know mine are fine, all the 210 are is wider so i dont see how it couldnt be sorted by simply raising the rear like Danny did.

    They are wider but they will have a slightly taller sidewall as the 50 profile is an aspect ratio of the width.

    set about it with a grinder.

    gayness mate.

    sorry to hear hope that get it sorted out ok n all

    Surely if its catching on the inner part you could file that away so the arch is alot thinner

    Please see my progress thread for an in-depth update. I think i've cracked it! Damn I'm tired...

    Absolutely right. The sidewall will be 50% of 205mm, which equals 102.5mm, which is quite a lot. 195/50/15 would give me a sidewall of 97.5mm.

    It's still there as an option, but fingers crossed I won't have to.

    shame in my head i cant type for shit lol

    Bastard! Explain how.
  36. #36
    its all to do with the virtual mind toad
    you basically have a human computer in your head
    all you need to do is think in binary code and the net will translate it for you
  37. #37
    Not helping!
  38. #38
    lol well witout going into massive detail and reveling my secret to the noobs (who will use this system for evil asking about ebay chargers and can i get 200bhp from my 1.1 staying n/a) i cant explain it fully
    the previose post is about as detailed as it gets lol

    My pal with a vw camper went for wider tyres and couldn't cut the arch back or he would have had to undo hours of fabrication, what he did was to get the back face of the wheel where it bolts to the hub machined down by a few mm. obviously if you go too far the inner edge of the wheel will touch the inner arch/boot.
  40. #40
    Fair shout mate. But like you pointed out at the end I'm afraid. There's virtually no room between the inside of the wheel / tyre and the chassis.

    Toad, when i had my mr2 turbo with the same probs i used a company (cant think of name) a few years back who specialized in arch modifications, they are a mobile company all over the uk so they will come to you! very good jod and i highly recommend them! like i said it was a few years back but im sure i still have the card somewhere so i will dig out the number for you.
  42. #42
    angle grinder hammer i had to do it
  43. #43
    there is plenty of metal to cut off under the plastic arch trim, and it's usually the rear bumper bracket that hits the tyre first also...

    Did alter the appearance of the arch / body from the outside?

    Seriously!
    I'm going to fit 205 widths to the XSi, and that has much skinnier arches and smaller trims so much harder to fettle! Where there's a will there's a way :lol:
  48. #48
    Great pic! LOL!

    Well, I don't know if what I've done is any help to anyone, but hopefully...

    I still get a bit of rub when I go over a speedbump fast, so there's work to be done still. I'm not sure what else I can file off. Also, I'm not 100% that I've got even ride height at the rear! : I need to take the car to a perfectly flat piece of tarmac to get a proper check. I might have a go at raising the rear a few mm, but I don't want to really.
  49. #49
    mate if you continue to have problems with shit make sure you are cool with car before sorting wheels n stuff.
  50. #50
    OK dude, appreciate it. I'm going to have a good look on Saturday, when I'm next free. Oh how I WISH I had a garage... with lights... and heating... Wowsers...
  51. #51
    lol i know what its like, fags house gravel drive, not much light and cold winter middle of nowhere air.

    dude no probs, like I say more important you have a car that works and is safe init, im not in a push push i need rimmage yo
  52. #52
    To do the rear arches properly you need to take the arch trims off, and the torsion bars out! Then when you drop the car down it will sit on the bumpstops, or wherever the tyre is rubbing, trim the arch etc so that there's a bit of clearance for when the bumpstop compresses, refit trims, job done.
  53. #53
    If I'm on a perfectly flat bit of ground... Should the rear wheel to arch clearance (height in other words) be the same on both sides?

    Tis a good point, lot of hassle though. I'm hoping that a good gander up inside the arch should reveal where it's rubbing... Fingers crossed.

    BTW alex, as you said you're thinking of going 205... They are heavy man! My r888s weigh 9kg each. Was gutted about that... Also, remember those bolts you sold me a while back? The ones for the engine, cam covers and that? They rusted to fuck! Got any rust-proof ones in the same size?
  56. #56
    yes as above. i am getting the 888's in 195 however my bars are huge and do not flex!

    i removed the mount and then moved it further down the arch
  57. #57
    We had no problems whatsoever with 22mm bars even doing over 120 through foxhole @ the ring That was with 195s though.

    Just take the bars out, it's a few hours work for piece of mind, if you go over a really big compression or something and it punctures the tyre you'll be screwed!

    Toad did you buy the black bolts? They don't seem to fare very well in damp conditions, if your car spends prolonged periods unused they will go rusty with the condensation that builts up in the engine bay! The stainless ones are great, i left some in a cup of water for a few months and they weren't rusty, just had some white stuff on them that brushed off :lol:
  58. #58
    Yeah, they were the black ones. At the time of fitting them, I drove the car nearly every day, and they still rusted to buggery!

    Can you sort me out some rust-proof ones?
