Rays Nismo Lm Gt3, Guard Rolling Rah Rah

[oweban]

Hi there;

I've had a set of LM GT3's since I got my car; they're all 18x9 and +26 offset (just had them all checked while they're being fixed; some of the stickers have come off while washing).

I've got an S1 R33 GTS-T, and with 255's on the rear they pop out slightly from the guards. No big deal, D2 coilovers with zero spring movement, but I'm looking at softening the suspension soon; I'd like to be able to go on a drive more than half an hour without my back hurting from constant bumping EVERYWHERE. A few questions about this though:

1) Is this an ok offset for the GTS-T? I had 275's front and rear when I got these, but on 235's on front now... Just trying to get that sorted out.

2) Had a look at topstage.com.au and it seems they do the kind of thing I'd be after; actually pumping the guards out a bit so they'll fit smoothly under. The guards are already rolled (I think that's what it's called? Basically the metal inside that's at the 90 degree to the body is pushed back up inside the body against the metal. So assuming the left of this post is the inside of the car:

\| (well really even more pushed against it than that)

instead of _|

To do this, would they need to respray the entire rear quarter? Or is that kind of thing paint-crack-less? Has anyone had this done and around how much does it cost?
