Best Rotors for My 2010 LS 460L
#61
I replaced my front rotors a couple of years ago and my rear rotors last year. Much of the warping/shuddering has returned, and since I need new pads anyway, I figured I'd replace the rotors as well rather than machine them. Doing this will also rule out the shimmy being caused by CA bushings and the like.
My pet theory is that Lexus hubs and rotors are sourced from separate suppliers (both parts fully within spec) and then mated only at final assembly. Depending on how the tolerances of the two components stack up in their random mating, you either get overall runout being maximized due to addition (and thus subject to developing shudder) or minimized due to cancellation (with a lifetime of smooth braking ahead). This would account for the random nature of the shuddering/warping experience by Lexus owners under what appear to be normal operating conditions.

FWIW, I've had the Stop Tech slotted only rotors on my FD for 2 years now and have been through 2 sets of pads and 6 track days (for brake mods the car has upgraded master cylinder, steel lines, hawk pads, ABS delete). I've never had an issue with warping and very little fade on track days.
I've been enjoying the rotors on the LS so far, but after reading here I started paying more attention and I can hear the front brakes at times when I am slowing down (mainly if I hit the brakes on the highway like from 70 - 30mph), it isn't really noticeable in the city and hasn't bothered me. BTW, I am loving my staggered ricer look, hahaha.

a lot of times, the initial resurface of the rotor will cause the shake.
a lot od shops like to make more money by reccommending a resurfacing of the rotors when changing the brake pads. This is a big mistake.
this is a big industry scam IMO. they charge u more to resurface them, which causes the rotor to get weaker. Then they charge u again to change out the rotors later.
