For those of you that have 28" tall tires on the front of your duster, what mod's did you have to do to make it happen?

What wheel offset? How wide of a tire?

Did you trim the fender at all?

Mine is getting closer to paint, and I'd just rather do this now then later if I have to...

Thanks!

My car with the 73 and up disc brakes, 3.5" Pro Stars with 1.75" BS, 28" M/T Sportsmans hit the front, lower edge of the fender. It fits in the wheel well fine, but hits the fender when you turn. I found out the hard way when backing out of the garage

Same here. I have 28" Hoosier race front tires on standard offset (1 7/8"?) Holeshot Wheels. I had to bend in the front lower lip of the wheel openings to clear and it sometimes scuffs the sidewall a bit up top. A lot depends on how high the front suspension is set as well as how the wheel is turned when hitting a bump.

ditto...
watch out also if youve got the wheel turned alot and you pull in or out of an elevation like a driveway/bump..
it can hit the wheel well lip at around 11oclock
youll notice a small indentation on the factory portion of the inner lip..its folded in a little extra bit..it hits right there..
i took a body hammer and dolly and massaged it up a little bit more..
that and the aformention'd front edge..
put a nice sipe in the outer edge of the tire first time i backed up with the wheel turned just right...fwiw.

2.25 backspace will help.

So is it just the lip, or does the outside fender itself need to get trimmed/rolled?

Anyone got pictures?

Thanks for all of the replies!

I run a 2.25 backspace wheel and trim the lower front edge of the wheel opening and then make a new strut/brace a little bit longer to push the fender out more. Just take 1/2" aluminum drink machine tubing straighten and smash the ends flat and drill.

On this car I actually made my wheel opening bigger and profiled the bottom edge since my car had to be painted as well.

The main lip of the wheel opening does not need to be rolled. I have never done that.

Maybe to get the proper rake when using cal tracs. So they can get the desired 5" front suspension travel?

At the track, to syncronize vehicle reaction times to a comfortable spot on the tree for the driver!

A couple of reasons.

1- Reaction time tuning.
2- To get the headers/oil pan off the ground a little further without making the front end look "jacked up".
3- At ride height, it allows the suspension more upward travel because it starts in a more compressed state.

Thanks for passing on the pics'... that helps a bunch!

In my case it is for the extra roll out to help lower the ET.
