Default 275s vs 315s

pretty well finished off another set of drs last night
at the track, I have been running 275-40-17s, really
like the look of y'alls cars with 315-35-17s :cool: ,
wondering other than looks is it worth buying wider
wheels? anybody seen much 60ft improvment?
thanks guys,
Wayne

Drags would be better than size for a 60ft. Course they make the 315 in a drag as well. The 315 is a handling monster. Great for turns and as you said, looks :cool:

Is your car spinning the 275 DRs right now? If not I wouldn't bother.

Do not forget that you are adding a LOT more unsprung weight to the car, without any upgrades in power. Don't be surprised if you actually lose some time.

So if you're not spinning a 275 DR, I don't think a 315 would be worth it.

yeh spinning enough I'am beating up the 275s pretty bad, I can get 1.78s-1.82s most any time, but spinning enough I THINK could do a little better

I went to 15" all around.. in front I have 3.5x15 with 165 skinny tires, in the rear pro Star 15x10" with 325/50/15 tires...

You will need spacers both front & rear, & have to grind the rear break calipers if is a newer car..

I love the way I launch..& hook up... however on the street you gotta take it easy in the corners.
Like they say you cant have it ALL if you want to fast in the 1/4 your gonna have to give up some cornering ability, if you are looking for the 1g in cornering with BIG tires all around etc.. you can expect slower 1/4 times.

Or the 3rd choice is to compromise, and NOT be GREAT in either, but "fair" in both...

As for me.. I like going from point "a" to "b" as fast as possible, so its big Drag radials, & slow in the corners..

my sway bar in in the garage.. :)

ditto on the swaybar and the only corner I like is onto the return road, but not sure if I want to go 3.5s on the front, I have run 6in with something like a 205/60, on other cars, kinda skinny but very driveable, any chance that would work-look right?
