Default Spring is here Spacers, rotors (New pics)

Was a nice day today, thought I'd snap some quick shots!

All the stuff used or featured in today's pics in case anyone wants some recommendations on stuff to use for detailing:

Rotors: Powerstop
Spacers: Amazon 20mm F/R
Wax: Collinite
Finish spray (sealer): V7
Towels: Chemical Guys













Powerstop rotors. Great value. We'll see how they perform! 500 miles in.


Pardon the LED weirdness...perhaps the PWM of the LEDs doesn't jive with the shutter speeds.

How did you hook up your fog lights? Where did you buy them and how much were they. Do you have any warning lights on the dashboard?

Did the stock studs stick out of the spacers? if so did you cut them down?

Didn't you say these rotors were trash and only OEM were good?

I needed the rotors in a pinch cause I found out my stock ones were very worn down at or past minimum thickness (1mm on both sides) and I had a long trip to do the following weekend. I got mine on a ridiculous sale for the price of one lexus rotor. Free shipping too. the lexus rotors required $90 shipping. I scored a steal. Also people usually combine their drilled/slotted rotors with low friction low dust pads. I've retained the high friction pads. The effective reduction in rotor mass is fine given my application (commuting) but for full out performance, the blanks are still preferred.

My posts are verified though as 500 miles in, the rotors are making groaning noises despite complete bed in. I'll be replacing them at next pad change which is coming soon. Do as I say, not as I do.

As for fog lights, they are completely custom made from factory Corolla LED units. Very powerful at night.

As for spacers, no modification required.

Thanks it definitely gives the car a bit more presence without going too crazy. It has just the right amount of fender overhang where it's not super obvious the car is modified. Appears factory.

No, I mean the sides of the rotor were reduced by 1mm on each side. Meaning I'm at minimum thickness. I think stock thickness is what 30mm and min. thickness is 28mm. So that means if you have a 1mm lip on each side, you're at about minimum thickness. I did not want to take any chances

Not too soon I think (18k), that's just what happens when you have high friction pads on summer rubber and drive a lot of street. I drive on the aggressive (I like to call it efficient) side. But no track/DEs or anything.

Yep there is a distinction between choosing drilled/slotted rotors as an upgrade for replacement (in that they will experience degradation in performance when comparing to stock) and using it for commuting. It's similar to driving an IS250 non F sport. You won't start crashing into things, the brakes are still great, but the level of friction and heat management won't be up to par of the IS350.

If you are choosing drilled/slotted for performance as a replacement for a car that did not come with them, then there is no benefit, and actually a downgrade as you've essentially reduced your friction surface area by a considerable amount.

Rotors still groaning btw. They stop fine and no wheel shake, just make noise as I come to a stop. Pretty annoying. I figure it could be the edges of the holes/slots rubbing against the pads.

I still stand by what I have been saying for years. Drilled/slotted on a car that was not designed for them is not an upgrade.

It's not a performance upgrade, but it's definitely a visual one.

The spacers are used to change wheel bolt patterns and/or to widen the offset of the wheel.
