Wide fenders?

I'm sure this has been asked before...sort of, but I can't find any threads with what I'm looking for. I'm looking for wide front fenders or bolt on flares ig enough to cover a 315. A complete front nose would be okay too, but was really looking for the easiest bolt on as I don't want to do side skirts and matching rear flares. I'm using the Pettit rear flares. Thanks in advance for any help.

Before I answer why I need 315's up front, may I ask why you think it's too much? Too much for what?

In all honesty i'm not the guy to be asking about this stuff b/c i don't have the technical knowledge about whether or not it's a good idea or not. Just really curious that all. The most i've ever heard of are 285's up front, and that was pushing it IMO. Really a noob when it comes to that stuff.

I guess thinking about it, cars in the JGTC run that kind of stuff with their extreme wide-bodies.

AMRX7 runs a special CF front clip from 7Parts.com. He has 315 F and 335 R. (http://www.7parts.com/andymckee.html)

I think Jack Madrigan (XS Engineering - http://www.xs-engineering.com/teamxs.asp?filter=1&id=36) also runs the fatty up front.

There is almost no conceivable condition in which 315s would be required up front....

1. in 99.99% of conditions they won't heat up enough
2. they will be damn near undrivable on public streets (tramlining anyone?)
3. there are no appropriate ratios to result in a tire of the proper diameter, a 315 is quite a bit taller than stock, which is bad up front, no matter how wide your fenders are
4. unnecessary drag, rolling resistance, and weight

How's that for starters?

One shouldn't talk out of their *** when empirically we have a multi-time SCCA National Champion proving otherwise.

Clearly Rynberg wasn't talking about autocross. If you would attempt a little bit more reading comprehension I think you might see that point.

I agree - 315s are really, really wide and would make for a horrible street driver. Autocrossing might be the only application where so much tire would be an advantage.

Thank you for that link. I have one of those nose pieces hanging in my shop right now, and fitment is sketchy as far as the 315. I'll have to contact him for some more info.

1. As far as getting a tire to heat up due to contact patch etc., that only comes down to choice of compound and driver capability.

2. This is not for a street car.

3. I get my race slicks directly from Yokohama. When it comes to a 315 and 335 slick I'm sure I will find something close in diameter. I have a set of 320's here that are 24 7/8" tall. How does that measure up to a stock tire?(not that it matters)

4. When comparing lightweight race wheels and slicks(also light) mounted on a 2150 LB race car, I'm sure i'll be ok with the weight/grip ratio I end up with.

Any other ideas on fenders not having to do with how to build my racecar? I do appreciate the contributors who sent me links so far. Thanks.

Moving to the Race sub-forum now that we know you are serious and not just a dumb kid (no offense, there's a lot of them out there).

Like I said, in 99.99% of situations, it would not be desirable. If the OP had declared his serious race only parameters in the first place, I wouldn't even have posted that.

I guess my reason for not posting about the purpose and build of the car was so I could get anyone to read it. There are fenders out there that may work that only a total ricer would buy. At this point, I'm looking at any options, so I left it generic. Didn't mean to cause any confusion even though I knew I'd get the usual "your tires are too big" answers and I's have to explain anyway. I would have started this in the race forum, but figured I'd get more response here.......and I'm a forum newb.

Dave before u insult u should do some more research and not act like all the other dicks that slam everyone. Synaptic3 posted his work in progress...it looks like a tube frame chassis FD. So stop assuming. **** i hate the forum nowadays..."everyone but stock sux" "you're all drift punks"

Not everyone is a young twit who asks for info just cuz it's cool. Mardikian's car is a Time Attack car so it's not autocross. I guess reading comprehension and blindness runs amok here.

You're reading waaay too deeply. The 3rd gen forum is almost exclusively about street cars; most race car builds are discussed in the race car forum. Context does count.

Not everyone is a young twit who asks for info just cuz it's cool. Mardikian's car is a Time Attack car so it's not autocross. I guess reading comprehension and blindness runs amok here.
1) Did someone call you a twit? Is there a reason you can't disagree without disrespect?

2) I apologize for not knowing what had not been disclosed. But nobody here owes any apology to you. The fact is, fitting tires of that size on an FD is hardly a common thing. Knowing the 'why' is useful in addressing the 'how', and it wasn't disclosed until later. I wish I could provide more info to the OP on this subject, but I don't. So I'm done.

Aaron, good luck, that looks to be a wicked project car.

Well, um, thanks guys. I think. Didn't mean to start a thread for arguments......but it would have been nice if a certain mod could have left the thread where it was. I DID post why I started the thread in the general forum and I think it was a good reason. Hopefully I still get some interest in the post and some more helpful answers.

Gravytraindg, thanks. I do know all the tracks up here. I'll be travelling most of the east coast with this car as it will be run in SCCA and NASA. I'm sure I'll be doing some autocrosses here and there for fun too. Vermont huh? I was just in a big TSD rally up there in the Barre/St. Johnsbury area. Huge snow storm, 10 hours straight of driving at night on back roads, and ended up on the roof halfway through. Loved every minute of it. Luckily I was just a NAV and it wasn't my car.

Fiberglas fenders

I run the IMSA Mk-1 bodywork that was designed in 1980 by Dave Kent. It will clear the 305mm wide Goodyear slicks I run on the front just fine. This body work has been copied by many companies, including ISC racing who sells it now:

http://www.iscracing.net/Fiberglass.htm

By 1984 there was a slightly more aerodynamic front nose used in IMSA racing, and that nose and front fenders are offered by Japco:

http://www.piner.com/japco/r3.jpg

Here is a picture of my SA chassis 13B PP powered road racer at VIR in 2004. I was playing with this corner; I found that if I yanked the steering wheel slightly after turn in, I could lift the inside front wheel enough to clear the curbs on the inside and drift over the curb without even feeling it. When the photographer made this shot, I was a little too far out of the apex to carry the wheel over the curb. Anyways, that is what the IMSA Mk-1 body work looks like.

Hi Aaron,

You have one of the 7parts front ends? I have my 315's on 17x11's, and they are about 25.5" tall. The 7part front end clears them easily, though I did trim off the lip. I think I can actually get 11.5's in there, but it will be tight. The bigger issue for me is with a 25.5" tire you have more clearance issues with turning the wheel. I needed to do a little banging on the back of the headlight assembly and frame seam in the rear of the fenderwell.

Not sure about availability, but I know Jeff Kiesel (7parts) had another front end piece made even wider that looks better.

Also-if your asking if you can fit 315's up front with XXX fender, or if your aking hot to fit 315's up front at all- you dont need to be running 315's.

Dave

Yes, by your statment about "my reading comprehension". Perhaps, you should not instigate things and then tell me that I'm disrespecting. You must be a lovely person to meet.


On-topic: Synaptic3, not sure if you are just looking for the front fender but if you're going all out, MazdaMotorsports has the Jim Downing complete GT-2 CF bodykit. Pricey, not super bling, but I guess it works and is allowed by sanctioning bodies.

It was more of a question about what body work I can use, as having to use 315's is already a given.
