Rear quarter wheelwell rolling question
I recently switched up from 245/45/16s on 16x7 phonedials to 16x8s(same tire size), and the rears are a bit too far out with the hubcentric spacers i'm running. I'd like to 'roll' the fender with a bat, but figured it would be a really good idea to get some input first, since i've never done this before.
Suggestions, concerns, opinions, etc. are appreciated.
Thanx.

Anyone have any luck with a "fender roller" to do more than just roll the inner lips? I have one, haven't tried it yet, though. ANyone with experience who reshaped (flaired) the fenders with a fender rolling tool?

Ideally yeah, i'd go with thinner spacers, but the hubcentric style ones are really expensive(as far as spacers go), and to be honest, i've spent so much money on the car in the last 30 days that i'd like to take a little break from pulling money out of my wallet- if at all possible. 
Of course thinner spacers would have the benefit of reducing my unsprung weight too.
Hmmm....maybe i do want to spend more money.
Oh, PS: My spacers are pretty big, i can't remember the exact size though. Definitely over the 1" porsche approves for 928s...but in over a year running them they've caused me no problems at all- until now.

You could always ebay the old spacers to defray the cost... or possibly just have a machinist slice 'em on down... It pays to have machinist friends/family sometimes... this job would probably cost somewhere between a sixer and a twelver...

Sadly i don't know any machinists well(i wish i did, it's really the one hole in my local car people network).
Hehehe, i could always try a brake lathe though...i can run one of those myself.
At any rate, i still want to get the scoop on the fender rolling procedure, just to know how it's done if nothing else, but you're right...i should definitely be looking at more narrow spacers, so i guess i will.
PS: LOVE your Petty quote.

I am not a fan of using a baseball bat but Mark Kibbort is quite skilled in the art of taking a baseball bat to a car and having it come out looking OK.
We do have a real fender lip roller and it works great for slight flare's also. It will apply about as much pressure as you would ever want to put on your quarter panels. I am running 11" rear wheels with a 45mm offset and 295/35/18 with nothing more than a flare on a couple of 928's.
The main trick you will need to remember is to heat the paint with a good heat gun to prevent it from splitting or popping off while reshaping the fender lip.

You can buy some smaller spacers at most ANY of the big auto parts stores.
I removed my big spacers when I put on my new wheels. It will also help save you $$ in future wheel bearing replacement!

I can't outright remove them, it will move the wheels in too far.
Right now i'd like to gain a minimum of 1/4"(which i understand can be accomplished by rolling?) to a max of 1/2".
The spacers are well over 1"(probably closer to 2), so yanking them entirely would set the wheels in much too deep for my tastes from an aesthetic POV.
As far as hubcentric spacers being available at local auto parts stores, not that i've ever seen, and definitely not for a Porsche bolt pattern(which is almost entirely unique beyond some old Mercedes van or something like that).

If you look at the pictures of my car https://rennlist.com/forums/928-forum/223007-new-wheels.html
you'll see what rolled fenders look like. On my GT the fender lips are already rolled, but Porsche allows a 10mm side to side tolerance in how the car sits on the rear suspension. My passenger side tire rubbed, so JimM took the equivalent of a baseball bat and put it between the tire and fender at about a 45 degree angle to the ground. I backed up and ended up with rolled fenders, not just lips.
You'll may also find that if you just grab the fender with your hands and pull you'll get the 1/4" you need. It worked for me but wasn't enough.

I have 16x8 S4 rears, with 21mm bolt on spacers, and 245/45 Kumho 712's. This combo fills the opening entirely, with approximately 10mm to spare.
