I'm really bored at work today , so I am starting a new poll to try and create some discussion. Thhis is kind of a follow-on to one of my other topics. Is a wider track (by using lower offsets) beneficial? All other factors being equal with the same driver, would an experienced driver using 17 x 9 with +35 offset be faster around most tracks than when using 60 offset? Is a 17 x 8 +50 nonstaggered setup better than a 17 x 9 +60 setup?

 

Dang these forums are slow. This is not helping to ease my boredom at work.

 

I'm not an expert but from what I understand the widest wheel that fits under your fenders is going to be the best one.

Something poking out is obviously going to hurt you by causing a drag penalty at speeds on track.

That being said I believe my vote is obvious.

 

It is pretty dead here. There are too many variables to determine "the best" but I prefer 17x9 +55 to 60 as it gives you good fender clearance for up to 255 tires, but not so extreme as to to mess with steering geometry (personal preference).

 

Well, I see what you are saying, but what I guess I am asking, is running a 17 x 9 +35 with wide fenders and overfenders going to be better than the higher offsets that fit stock fenders? I am not concerned about the cost of bodywork, but moreso whether this setup would be better.

As far as wider is better, I would think that to a point...255s are a little stretched on a 10" but one member I remember said the feeling of the 255 on a 10 was better than the 255 on a 9.5 or 9" wheel to him. But wouldn't there be a point where adding too much width to tires need to be countered with extra power because of the rolling resistance and or/weight? Like 275s all around for example.

 

i'd like to know this too.

i know in theory it should give more grip, and change your roll center (from what i've read). and would also apply more force to your shocks/springs, and thus might require a stiffer setup to compensate. beyond that, dunno.

in events where there are no budget constraints, or even any design contraints, cars still never have wheels pushed ridiculously outward, so i assume at some point advatages outweight disadvantages. wish i knew what the tradeoffs are.

 

Yes, I am sure track width and tire sizes are just a couple of the variables...I am sure modifying suspension might be advantageous if there are major changes.

But a lot of the major "racecars" seem to be running widebodied vehicles, so it seems like there has to be an advantage:







All the major Japanese tuners have a widebody: ASM, Js, Amuse, Top Fuel, Tracy Sports.

Is the only "disadvantage" that you add points if you are trying to stay in stock class or like the TTC for time trials?
