Rolled arches

[Mark B]

Hi All,
Has anyone done this to their car? Is there anything to look out for?
I’m wanting to fit wider wheels on the rear.

Done it a couple of times, not as easy as is sounds....
I think the biggest gain is to get wheels with the correct back-spacing.
In reality the rear tubs on a Challenger are very big - bigger than most similar cars.

If you are really going for it, you may need to in-board your rear springs too.

The lip area you are trying to roll is quite thick on these cars, I've never managed to roll the section successfully. You tend to end up breaking out the hammer and it might look ok from the outside but it's messy and you are defiantly creating a water trap. What I do these days is trim the lip back to about 1/2" wide, tack weld the 2 panel halves back together if you have gone beyond the spot welds and use panel sealer to fill any gaps to keep out the water. To the untrained eye it still looks factory.

Thanks for the recommendations. Yes that’s the problem, the inside lip is 40mm deep and yes there are new rear quarters fitted with spot welds around the new and old lip. I guess if I roll them could get messy. I was thinking of using a grinder to cut the lip back to 15mm with a thin disc. Do you recon that the best way?
Thanks for your help.

Yes that’s exactly what I’ve done on both my cars, done with care it doesn’t affect the surrounding paintwork.
