Title: Rolling arches....
Post by: tomlang89 on 28 July 2010, 15:04
I've just got some new wheels using adapter plates, tyres are 195/40/16.
The tyres rub on the rear arches so I am going to roll the arches unless anyone has a better idea? Also how do I do this? I'd like to try it myself, already taken off both plastic arches so ready to go! Or is it better to get them done by my local bodyworks?
Cheers
Tom

you will need an arch roller to do it yourself, properly. i borrowed on off a friend and did mine. beware that the paint can crack!

best off getting quotes from bodyshops, as they most likely need some filler and a respray after.

et23 I believe, they are these wheels http://www.porscheclubgbforum.com/tm.asp?m=523020

I'm going to get the car resprayed at some point in the next year and the car will be off the road in 2 months so not bothered about paint cracking etc, is this the best option? I am currently running standard suspension and saving for coilovers, just hoping the front arches will be ok after it's lowered!

How thick are the adapter plates? Must be about 20mm and there lies your problem!

So et23 less 20mm means et3, going to need more than the arches rolled to be honest.

Even 15mm adaptor plates will leave you et8.

Major work needed.

Serious work needed to sort these puppys out especially if you CAN rub on standard suspension!
Bodyshop ftw!

it rubs on the rear when the car has 4 people in accelerating and going over speed bumps. I'll take it to the local bodywork shop I think as I want it done before I get coilovers...anyone in cornwall with an arch roller i could borrow please?! :D

If it is rubbing now what hope have you got when you lower it.

Is it rubbing on the arch lip or on the arch itself?

If its rubbing on the lip you will see where it has worn away part of the plastic arch trim and taken some paint off.

If its rubbing on the arch you will see scuff marks inside the arch / wing.

Depends on where its rubbing as to how drastic your modifications will be. Rolling and flattening the lip is fairly easy for a body shop or to do yourself but moving the arch out is a harder job and probably best left for the pro's.

OK then you'll need to remove and trim the plastic arch trim.

Then you will need to roll the lip on the arches. You can do this by heating up the area gently with a paint stripper gun and then you can carefully roll the lip flat with a baseball bat or broom handle levered against the lip and the wheel. Go carefull do it a little bit at a time and keep the paint warm to stop it cracking.

Or you can buy a proper arch rolling tool for over £100, or take it to a bodyshop, or I seem to remember there is a firm in Exeter who hire out the tool, I can look out their details if its close enough for you to collect it.

Also worth looking on ebay I think there was a few firms hiring them out on there.

There was an interesting vid on youtube about arch rolling - some suicidal Jap did it with a thick metel pipe trapped between the wheel and arch and then drove his car forward - nutter.

That id like to see,

What i did for mine is to remove the arches and trims, block of metal on the outside and hammer on the inside (proper hammer-tapping kit thing) and that got rid of the lips.
