S13 Drag wheels

[Jimefam]

I'm building a drag S13 and wanted to find out what size drag wheels I need to buy to run the largest slicks possible. I'd prefer people with actual experience and not what you think might fit. I plan on running 15" rims unless you know 14" will clear the stock brakes.

in order to fit the largest tire possible, you must buy the largest rim possible. post hoc ergo propter hoc.

and you're running a drag 240sx with stock brakes? yeah i hope you run out of track.

oh and getting the largest tire possible under your car won't get you the fastest times. there is a ton more you have to consider than just size... brakes should come first though. seriously.

You have a 1/4 to slow down at the drag strip.... stock brakes do the job all day.

AS far as drag wheels.... when I was looking into it I was gonna do a 15x10 with a 6 or 6.5 backspace and run a 275-50-15 DR or 26'' x 11.5'' - 15''LT

If you doing a drag only car, are you doing a solid axle? if not tub it out and run a 15wx30H tire

[Jimefam]

Yeah he's correct stock brakes will be plenty for drag specially with the parachute helping out. And the largest tire possible still won't be big enough.

Thanks for the replies so far.

If they can lock the disk that as 'strong' of break as you will ever need. Stocks can lock them up, so stocks are as 'strong' as you would ever need in any motorsport application.

BUT, bigger breaks dissipate heat faster and better so they will fade less and last longer.

Brebos or any other BBK only cool better, they do no stop you faster. The only thing that can stop you faster is tires. (or the parachute mentioned above)

I will eventually go solid axle but for most of the classes I want to run the chassis has to be unaltered. Also I already have z32 aluminum brakes up front, not that I would need them for drag. Thanks

I used to drag a ton, I never had to really use my brakes over 50 MPH. I would always just let off the gas and decel in gear for about 1/8th of that mile down shift and then brake coming in usually around 25mph. And this was in my old drag car which ran low 10's consistently.

More so if your running a parachute, how fast do you plan on going? Because the IRS is not ideal and you will be breaking axles, especially after continuous launches. How much power we talking, how fast, NA or boost?

[Jimefam]

That's why I attached my build thread above. I will be making well over 1000whp through a TH400 and a carbon fiber DS and they're 1200HP axles.

are we talking calipers or rotors here...?

Good luck with the build man, it looks awesome so far

[Fenris]

Yes

Once the wheel is locked, which stock brakes can do, how does having a bigger brake matter?

The only thing that slows you down, is the friction of the tire on road. (or air brakes or parachutes)

The maximum way to induce friction in theory is to lock them. Granted control wouldn't be that great in that situation.

So, granted, bigger, more pot brakes could lock them faster, but stocks will do the same just as easily.

The big difference is that bbk rotors can vent heat better, and bigger rotors need bigger calipers. Less heat is less fade.

Not entirely true. Locking the brakes locks the tire, and a locked tire will not slow down a car nearly as fast as using maximum tire adhesion.

Bigger brakes allow more control over the braking force, allowing you to better modulate brake torque.

Also, with the right tires, locking up stock S13 brakes can be nearly impossible.


Its really a moot point thought. If you are dragging legally, then there is plenty of run down room, and huge brakes are not necessary. Its only if you are a retard street racer that you worry about something like that.

In truth, drum brakes are actually better for drag racing. If you are power braking with disc brakes, the force placed on the pad can actually hang it up, seriously hurting 60 ft times. Drum brakes release in a different way, negating this issue.

And remember, when you dont need them, every ounce counts, big a** brake rotors are heavy.
