Help me choose a C5 rotor (warning- actual corvette topic)
 

to recap- cheap chinese steel plus ceramic pads operating beyond their heat range:

I will most likely get Hawk HPS pads because they are already on the rear of the car. They work pretty well, gonna stick with that. The problem is the ZR-1 is heavy and I can't go cheap on the front rotors.

I'm looking at the Powerslot & Powerslot cryo, EBC rotors etc. No two piece- I'm on a budget because I have to do the front bearings at the same time and this job is gonna exceed 6 bills. I just want solid metallurgy for hard street driving.

Any experience with C5 rotors- let me know.

Mike, is money an issue?

Wilwood sells OEM size rotors. They have drilled/slotted and slotted.

The ones I had on The Ghost were from IRotors on eBay and they held good.

I would recommend NAPA premium rotors. They are around 50 bucks.
Also, if you are really cheap, call companies like LG/LPE/Callaway and ask if they have take off rotors for guys that do big break conversions. Sometimes they will just give them away. Of course, shipping..

Yeah, I'm not looking to upgrade, just a quality replacement rotor is all I want. I'm starting to get C6 perfmance upgrade thoughts plus I still have a car payment on the mustang, so yes, I'm on a budget. I figure I would not sell the car with loose bearing and cooked rotors so I will at least take care of it this summer to meet my minimum standards. I'll look @ the irotor option. I saw yours b4 and they seemed to be holding up.

Mike, it doesn't look like you want to go stock but if you change your mind being on a budget you might want to look at Corvette Recycling. They can have some really good deals on new old stock.

:iagree:

Oh...no way I'm going back to J55 brakes- have you priced those? (C5 brakes are half the cost)..plus my orig calipers need to be rebuilt. I actually have very cool two piece C4 J55 slotted rotors, but the pad is small and I'm gonna stick with the C5 conversion.

If I could get genuine Canadian made Raybestos foundry rotors, that would be cool, but I'm willing to spend $110 a pop for some kind of aftermarket premium stock (C5) replacement, just not a $600 set of two piece C5 rotors or anything real exotic. Consider this more of a repair and not an upgrade. I'm also gonna give the Timken bearings for the F-body a shot (courtesy of RedLS1GTO's thread) since one side finally went out of spec.

ZR-1's are heavy, but with the dual diaphragm booster, the brakes actually work. I should have done it right the first time since the weight of this model is so hard on them, but between the missing parts for the brake conversion, the ZF rebuild, $1000 set of tires, the FX3 rebuild, $700 for 16 stainless injectors, and hundreds of dollars in misc knick-knack repairs, I had to compromise. Lasted a year and a half so it wasn't too bad.

Mike, he meant stock C5 brakes.

well, I'll check for oem C5 stuff from those guys and maybe those Irotors.

Decided to get some slotted EBC black zinc coated C5 pieces from Summit (free shipping and no sales tax):

got the Hawk HPS pads too, but still waiting for the hub bearings. I think the rotors are cast in the UK, but no indication one way or the other. The do say they are made out of a premium SAE steel of some grade that sounds promising.

SKF branded 4th gen F-body hub bearings #BR930186.
These are made in Korea, but have been reported to be of very good quality according to tech tips on CF and this post here on VB: https://www.thevettebarn.com/forums/c...-bearings.html

I was able to mount the abs wire bracket even though you have to run the bolts thru backwards. Some people drill out the threaded holes in the hub and use the nuts like the oem C4 uses, but you really don't have to bother. The bracket just acts like a washer- the knuckle facing is flat enough across the back and you don't have to modify anything. Notice I installed the nuts on the bolts even though the hub is threaded...I just didn't want to lose them and just put them back on the car just in case somebody gets oem vette hubs and needs them again.

bad picture showing the abs bracket behind the bolts- originally sits on the threaded studs coming thru the other way-

the only thing I did was bend the ABS wire bracket out 1/4" to keep the same slack in the line as it did previously when it was mounted inboard a little closer.

done...

and there does not seem to be any ABS issues with different pulse counts per revolution. I haven't tried to lock the wheels up yet, but I'm sure everything is the same or the light would have set in normal driving if the pulse count wasn't right.

Mike, What was the price difference? F-Body Vs. Corvette

I have SKF on the rear of The Ghost and I trust them with my life. Also recommended by our motivated moderator.

BTW, the SKF #BR930186 is more expensive now. When i first started looking into buying these, the were $130 ea. I bought them for $142 last week, and I must have triggered a minimum stock reorder when my two got shipped out because they are $157 ea as of this posting.

ON EDIT- this p/n is only for the 91-96 cars.

MaM lists them as not available with the last price in the $300's per each hub bearing. Parts stores list some other imported units for like $170 ea, maybe somebody has a cheaper one somewhere, but these Korean made SKF ones were both cheap enough and known to be good so I went with them. I did not look into buying oem ones too hard. I figure if people figured out to use the F-Body unit, it was to save $$$.

169 at Rock Auto..Still a good price for a SKF. I did the rears with SKF a while back. I have OEM fronts with Mobil synthetic bearing grease I got from someone who used to race Corvette Challenge. 100 for two.
Forgot his name, but he is in the roadracing section of
Rear SKFs at Rock AUto are BR930024 157....

^^^ How do you grease them?

special made from the factory, right?

Reher Morrison had them made for the Corvette Challenge series. These were still new in box. He has suspension pieces in a good sized shed.
I can pm anyone that wants his name/email

I remember in 1997 you could find an aftermarket greaseable bearing for our C4s. It used to be for sale on Corvette Fever Magazine.

Didnt Brian Cunningham get RJM replaceable bearings for his 95

Don't know, did a search nothing came out. What does RJM stands for?
