Wider front fenders

TBOX · 06-30-2011, 11:59 AM

I've seen advertising for several brands of replacement carbon fiber front fenders. Particularly seibon I saw was 10mm wider.

Can anyone confirm where this width is located? Is it a rolled lip? Could I use this to attain extra wheel space for wider tires?

Are the other brands wider as well?

How wide do you want to go? I run a 315 race tire up front without any issue. The trick is just finding the correct offset and running enough camber.

I understand my alternatives for additional clearance. I am weighing additional options.

I clear now, I want to gain additional clearance without altering camber or decreasing tire size. I run a 265 up front with a 22 offset.
I was considering cf fenders anyhow so I'm just trying to find out where the 10mm comes into play.

But I am interested in info on your 315 setup if you care to share. I think you mentioned before you run a 3.something degree negative. What's your offset, wheel size, brand of tire?

The stock fenders have the lip for strength, I would imagine that CF fenders are rolled by design. The wheels are Forgestar 18x10 ET+37 with 5mm spacer. The 5mm spacer was necessary to prevent inside rub under tire flex, so the ideal fitment (for maximum tire size) would be a +30 offset. I'm confident that a 18x10.5 or 18x11 would also work at that offset and I may try that at some point. Camber is -3.5 degrees.

We have a new fender coming out this year that will be 25mm wider than stock. We already started on the prototype a week ago

So are they going to be wider or just a wider fender opening, ie rolled lip

bullitt5897 · 06-30-2011, 07:21 PM

they will be a true wide fender which will come with our adapter plate for the front bumper. The fender is being modeled after the J's Racing s2000 wide fender concept.

That'll be interesting on a z. I'm curious what it'll look like
