So I was reading this article with this excerpt. I know rear wheel bearing failures are somewhat "common" problems..do you think it is mainly due to heat of the solid rotor, or increased load on the wheel bearing from a leading caliper?

However, there is an effect on bearing loads. It might seem counterintuitive that we can change the bearing loads and not change the tire loads, but that is in fact the case. As the questioner appears to have considered, the disc tries to carry the caliper upward if the caliper is trailing, and downward if the caliper is leading. That reduces bearing loads if the caliper is trailing, and increases bearing loads if the caliper is leading. However, these forces are reacted entirely within the hub/bearing/spindle/upright/caliper/disc/hat assembly, and do not change the loads on other parts of the car.



We can think of it like this: Gravity acts downward on the car, with additions and subtractions due to inertia effects and aerodynamic effects. The road surface holds the car up. Or, we may say the road holds the tire up; the tire holds the wheel up; the wheel holds the hub up; the hub holds the bearings up; the bearings hold the spindle up; the spindle holds the upright up; the upright holds the suspension up; the suspension holds the sprung mass up. If the caliper exerts an upward force on the upright and a downward force on the disc, that just means the brake is helping the bearings and spindle hold the upright up. It doesn’t change the total support force, only the load path within some of the unsprung components.

 

Dunno, still have a bunch of stuff to sort out. Right now we are scrambling to get our lemons car ready for a race at the end of March so the S2000 is going to sit for a few weeks.

 

To those looking for a new FF helmet. I picked up the HJC AR-10 II from OG back in December and I am really happy with it. (They will also match discount codes from saferacer)

 

IMO it's due to people running wider tires and more camber than stock.

 

But in that case, wouldn't there be a lot more front wheel bearing failures, since a lot of people switch to a much wider wheel and tire up front, and add camber joints? I usually only hear about rear wheel bearings failing.

 

Ordered.

 

Could we talk tires for a minute? I have no wing, no big-FSB so thinking of staying staggered but going r-comp with Hankook Ventus Z214. (F225/50R16 & R245/45R16) I know the general consensus is to buy 17" wheels and run 255 square or 225/255... but that's not happening right now.

I believe it is a heat soak issue from the solid rear disks. The hubs get freakin' hot from track use and bake out the grease. Improper (low) torque on the axle nut is also an issue with some failures.

I'm not familiar with the Ventus tire but staggered 16 inch r-comps should work fine with the stock sway bars and no wing.

 

Aaron - you getting back on track or is this for autox?

on a different 16" tire question, I have a set of 225/50/16 rs3s square on some 16x7 wheels I used to run on my rsx. I'm driving a 00 so I know I have the biggest front sway from the factory. New wheels/tires are not in the cards until these die at a minimum. Is it going to just be a spin-happy mess at auto-x and when I eventually get it out to the track once I buy my hard dog?
