Title: Brain teaser for you.
Post by: Rudemouthsky on February 13, 2014, 02:43:54 PM
I could blame it on my malady of mental issues, or just admit I suck with numbers...or admit I'm stoopid. Whatever. But I posted this on my political forum and now here, so we'll see who's smarter: Ducati Monster riders or Libertarian Socialists. :P

I have to buy pads and rotors for my wifes car. I need:

2 front rotors @ $43.99 each
2 rear rotors @ $42.99 each
Set of rear pads @ $35.99 each
Set of front pads @ $41.99

I have the following coupon codes;

35% off any order over $50 with a max savings of $50
$40 off any order over $100

Obviously I'll need to split up the orders to maximize my savings. What is the best way to divide the orders without leaving a single penny on the table?

Correction - Submitted when I didn't intend to:

I did it to get as close to the $50 max for the 35% coupon.  Here's what I got:
Fronts added up = $129.97. 
Using the 35% coupon your 2 front rotors & Front pads = $45.48 off that total (that's almost the max)
Final total for the fronts:  $84.49 plus whatever tax and shipping.

Your rear rotors and pads total $121.97.
With the $40 off $100 you get $40 off
Final total for the rears:  $81.97 plus whatever tax and shipping.

That doesn't compute. I'd get no discount on the rear pads.

You've got a total of $251.94 with no discount.

First, the smallest total over $100, to get you the closest to a 40% discount ($40 off of the over $100)

That's both sets of pads and one rear rotor, $120.97, getting $40 off.

Then the rest, which is $130.97, with a 35% discount, $45.84 off.

Leaving a total cost of $166.10.

Thanks guys, but everyone was wrong.

Getting closer to $100 would have been beneficial, but the closest combination still fell short of a 35% savings by over $2. Once the total gets over $110, the $40 off coupon becomes a worse deal than 35% off.

By buying the front and rear pads with one order, and both sets of rotors with the other, my grand total was $163.77.

Funny, when I do it that way, my calculator says you spent $184.65.

Pads, 35.99 + 41.99 = 77.98
77.98 x 0.65 = 50.69

Rotors 2 x 43.99 + 2 x 42.99 = 173.96
173.96 - 40 = 133.96

133.96 + 50.69 = 184.65

My post says you spend $166.46.  Not a bad price from front and rear discs and pads.

Post by: Rudemouthsky on February 13, 2014, 06:14:03 PM
None of this matters, because now I have to research every facet of brake pad and rotor technology. Drilled and slotted rotors will cool faster meaning less brake fade at the expense of slower stopping distance. I also have to consider whether or not the extra corrosion points in a slotted rotor is a bad idea in crummy OH weather. Then there's metallic vs ceramic pads. It's simple she says, just find me new brakes and install them she says. BS, I'm gonna be up all night researching this shit then she'll wonder why I haven't come to bed.  [bang]

It's a flat 35% off the way I'm doing it. $77.98 + 173.96 = $251.94 X .35 = $88, $251.94 - $88 = $163.94

~~~SNIP~~~

You said max savings of $50 when you use the 35% off, so *not* splitting the order will have you paying 251.94 - 50 = $201.94.

I remember being at a convenience store in Westland, MI (or Wasteland, if you prefer) years ago having a hard time deciding which beer or soda to purchase.

One of the locals asked me if I couldn't make up my mind.

I told him I was in a conundrum.

He said, "what?"

I then told him I couldn't make up my mind.

Set of front rotors and a set of front pads in one order. Set of rear rotors and rear pads in the other. It's an online coupon code, I didn't realize I was giving the impression it could only be used once.

Turn off the treadmill and the car will slow come to a stop, no new brake pads needed.

Well I can't speak for Toyota but I've noticed a huuuuuge difference in quality between parts store stuff and what Honda sells.

I probably went through two sets of pads and rotors vs one Honda set in the same mileage. Not 2x the price either.

Just a thought.

This.

Always consider OEM in my parts options.  I've seen some pretty shoddy parts store junk out there.

Post by: Rudemouthsky on February 15, 2014, 02:08:47 PM
I never get the cheapest parts store option, and for pads I always get something with a lifetime warranty. And use it...repeatedly lol.

Still haven't pulled the trigger, I'm talking to a company called Brakemotive that is very well regarded on the Ls1tech forum about slotted rotors and pads right now.

No, but the price is right and the feedback is good. She's going to be a test dummy for these too as I may get a nickel plated set with black hats for my souped up Pontiac GT. I wouldn't put them on her car if I thought safety was going to be an issue either.

I was thinking the same thing.  

Using slotted/drilled rotors of the same size as stock reduces the amount of friction available due to less surface area in contact with the pads.  You would need to upsize the rotor at a minimum to see any benefit over stock.

Go with a high quality stock type rotor and some premium pads.

Or maybe you're married to Danica Patrick...                 [thumbsup]

The manufacturer touted various studies published in SAE technical papers, and being a reasonable person I of course looked for objective criticism of those studies. She'll be fine. My wife and son ride in that car, ya know... :)

The only 2 drawbacks are the increased areas for corrosion to set in bc of this shit OH weather, and the slight sacrifice in initial bite because she tail gates, lol.
